Brief

It is used in an AC power system with rated voltage less than 1.2kV to increase power factor to reduce reative loss and to improve voltage quality.


Main Features

a. Novel in structure,light in weight
It is produced with Zinc-and-aluminum metallized polypropylene film as the medium so the dimension and the weight is respectively only the 1/4 and 1/5 of the old.
b. Low loss
Because the actual value is less then 0.12%,energy loss of the capacitor itself is few,the raised temperature is low,operation life is long and it has outstanding saving energy result.
c. Good self-healing performance
Medium partial impulse caused by the over voltage can healed by itself to operate as before.
d. Safety
It is very reliable because the discharge and insurance devies are installed in it.
e. No omitted oil
Its main immersed agent is the micro-crystal wax,which is solid at normal temperature,its drop-pot and dissoluble-pot are both above 70℃ and it won'omit operating,so it won't pollute the surroundings.

The installation and size of shape


Q:i have replaced this fuse 10x in one day. keeps blowing. it controls the pw mirrors,pw,pwr locks,heated seats, and i think the dashboard lights and radio illumination. they are also not working. does anyone out there know what the prob could be. im hopoing its something simple and i can avoid going to an auto electirc shop and get taken for diagnostics and labor. your help is greatly needed and appreciated. thanks
I'm gonna say you have a heating pad shorted out in the seat.try shutting off some of the accessories and see what happens, might be able to track it down yourself, might cost ya a few fuses.
Q:I have a 1988 Jeep Comanche Sportruck and all of the gas, speed, etc gauges are not working. The lights that lit up the gauges used to work before I recharged my battery, since the jeep was left sitting for a couple months. But ever since I had the truck none of the speed, gas, and all the rest of the gauges have been reading/ working anything at all. What could the problem be and how could I fix this myself before having to go to a repair shop? Thank you for your help I've had this problem for so long and it's just time for me to fix this.
Check fuses, if not a fuse, replace the dashboard gauge circuit board. DISCUSSION: Check the simplest and cheapest things first (fuses). If it is not a fuse problem, the easiest (and possibly the cheapest) step is to replace the dashboard gauges with parts from a junk yard. You might have blown the voltage regulator on the dash board (not the voltage regulator associated with the alternator). The difficulty of getting out the old dashboard gauges, and replacing a single component is slightly more than the difficulty of getting out the old dashboard gauges and replacing the who dashboard gauge circuit board, gauges and all. You might have also blown some gauges, so even if you fix one component, you might have to go back in to fix more. It is better to recharge the battery when it is disconnected from the car (to avoid the possibility of blowing out sensitive electronics such as dash boards).
Q:I am trying to install a additional parts to my car. when i remove the bare PCB with lcd from the head unit. i accidentally grounded the circuit board to the Metal plate, it create a little spark. now the LCD doesn't work. my question are1. is the circuit board fried?2. could it be just a blown fuse?3. after ground the board, could it be just burn resistor?
concorde develop into only grounded till the subject develop into fastened. in certainty the accident only exceeded off because of the fact a bite of metallic had fallen from yet another airplane. The burst tire hit the gasoline tank, yet that's no longer what brought about the crash. the burst brought about a marvel-wave, and located a weak spot, which develop into yet another place in the gasoline bit. yet yet that wasn't the subject. flames have been considered in the back of the concorde, what set this off? it develop into in certainty slightly the tire excellent the cable of the landing kit. this explains why the landing kit would desire to no longer be raised. the only clarification is the the loose cable striked the gasoline with the sparks, and brought about a hearth. The NTSB cautioned some transformations, and till then all concorde flights have been grounded. the advancements have been thicker rubber on the tires, strengthened landing kit cables, and a bulletproof furl tank. those style of have been easily fastened, yet concorde desperate to stop their corporation, as they have been given much less salary than for it to run. that's a very distinctive count to the 777, in certainty there is not any particular issue with the actually airplane, its hassle-free errors made by utilising the floor team and the flight engineers. i say they might desire to acquire greater coaching.
Q:I have already checked the fuse and it is fine. If I bought some freon would that maybe get my air back on? If not, any ideas on what else could be be the problem?
Fan motor could be effected by a fruse/relay. If you have this working but still no cold air then you need to recharge your system.
Q:I am going to run one wire off my battery terminal to an auxillary fuse block under my dash. The fuse block has 8 places for 30amp max fuses and the block is rated for 120amp total. The wire I will be running is about 8'-10' long. What is the formula used to figure what gauge wire I need?
There really isnt a formula for such a short run. You need to determine how much current your device will utilize (radio maybe 10 amps, or a light maybe 5, etc) Once you determine how much current your device will draw, you then determine the proper gauge wire.
Q:I was able to find out what the source of amperage draw was coming from, and it is the IOD. It is drawing 0.426 amps. The meter reads 0.923 and the Vehicle reads 0.497 without it installed. Generally, vehicles should have this amount to begin with correct? What could possibly be the issue with the IOD? Why is there an excess in amperage draw?
Because many of the modern electronics that run the engine, the radio, the car alarm, and a lot of accessories all need a small amount of current to keep settings stored in their chips. All your radio stations, engine errors record and some other settings you've made or the car has made would disappear without these current draws. I do suspect that your car alarm is the main culprit, probably drawing nearly a half an Amp when it's on for the sensing circuits and monitor circuit. I wouldn't worry about an amp to an amp and a half. Most modern lead acid batteries carry a cold cranking amp rating of hundreds of amps. If you are having trouble starting in cold weather or after the vehicle sets for a few days, better to investigate the condition of the battery, cables, terminals and alternator than worry about less than an amp draw. It's just a sign of the times, everything needs juice. I hope this helps you understand what's happening a bit better.
Q:i have 2 12 mtx tr75s and a 1000w alpine amp and a 4 gauge boss wiring kit i blew the 60a fuse that came with it within 2 days and blew the 80a today after just buying it should i go with the 100a or 125a agu fuse
the fuse is there to protect the amp.if you keep raising the amperage of the fuse you could risk damaging the amp. If you are blowing fuses too easy one of the first things I would check is make sure that all connections are tight and secure, meaning not touching any metal or any other wires this goes for the amp wires and the speaker wires.also the amp is designed to operate at a certain ohm level, ex. (1 ohm, 2 ohm, 4 ohm or 8 ohm) 1 and 2 ohms are usually used for spl contest, 4 ohms is the average with cheaper amps and subs. Since you said you have 2 12's you may have it wired up in a 2 ohm configuration while the amp can only take 4 ohms. The way you wire the speakers vary based on how many voice coils each speaker has and the ohms of those voice coilsI'd say figure out what ohms the subs are and then figure out what ohm your amp is stable at and search multiple speaker configurations. example, lets say the subs are 4 ohms and and the amp is stable at 4 ohms, your search would be wiring configuration for 2 sub woofers on a 4 ohm amp once you get that figured out put the fuse that was rated fir the amp back in and try again, if problem persist i would start taking to the place you bought it.
Q:I have a 2000 Chevy Tahoe 5.3L. The front AC works fine, it blows nice cold air. The rear AC does not work. When I turn either of the overhead ac control swicth on, I can hear a click in the rear passenger pannel but no air comes out at all. I checked the fuse box under the hood and the HVAC fuse was blown (30A). I replaced that and turned the rear ac back on. Again, I hear a click in the rear panel. I can hear that everytime I turn either switch on each controller on and off. Went to check the fuse and was blown again, but I can still hear the clicking sound in the rear even with the fuse blown. I believe there are 3 components in the rear ac system. 1) Hot/Cold Actuator 2) Floor/Ceiling Actuator and 3) Control Module. Now, is one of these bad? Where is my problem? I don't want to start replacing parts without knowing what is really bad on my vehicle.Please help. Thanks
Should be in the blower itself, not the actuators. What you can do is get a short finder so you dont have to keep replacing 30A fuses, but unplug the relay in the back for the blower motor see if the short is before the rear HVac or inside the rear HVAC. If it doesnt blow then insert the relay unplug the blower itself see if it is the problem. Maybe it or a short in the wiring somewhere
Q:Getting a fuel pump to work in a 1992 Saab
Check fuses and relays, you need the wiring diagram and component locator. The wiring diagram will help you trace the circuit. The ECM usually provides the relay ground circuit and the relay provides the power to the pump.
Q:I have a rotel RB-850 that won't turn on after working fine forever. Power light does not come on. Someone suggested it might be a blown fuse.
I repair these - it is never just the fuse! I urge you to not attempt to just replace the fuse. Fuses do not go out due to age, they blow to protect other components from further damage and/or fire (no, I am not kidding). The amplifier requires service by a qualified technician. There are no user replaceable parts inside. Those Rotels were good units and worth the repair. Your best bet will be a stereo/home theater store that does repairs, although you may find a TV repair shop that has an tech that knows vintage audio. Now put that screw-driver away before you hurt yourself.
