Product Description:

PTC thermistor alloy wires for Temperature Sensitive Resistance

PTC Alloy wire has medium resistivity and high positive temperature coefficient of resistance. It is widely used in various heaters. It can automatically control temperature and adjust power by keeping constant current and limiting current.

Temp. Coeff. Of Resistance: TCR:0-100℃    ≥(3000-5000)X10-6/℃

Resistivity: 0-100℃    0.20-0.38μΩ.m

Q:How to use the capacitor to test whether the wire is broken
A DVD drive, all system disks, most common drive disks and CDs. Probably about 2000 or so
Q:Apple 6splus charging may not support this accessories how to do
You can use the yellow wax tube, a single proposal as little as possible, generally in the concrete can not slotted the use of yellow wax tube Advantages: shallow slot location, convenient concrete wall construction Disadvantages: late maintenance of the yellow tube can not drag the line Moving, not easy to repair
Q:What does the cable factory need for technical change?
(U.L1) is yellow, B phase (V.L2) is green, C phase (W.L3) zero line (N) blue, ground wire (PE) according to international practice. ) For the two-color line.
Q:1 threading tube to wear two cable, easy to wear not? How long does the cable line take?
Oxidation, and the main reason for this situation is the long-term overload of the wire lead to accelerated oxidation and wire storage for a long time
Q:3 * 185 + 1 * 95 What is the price of copper cable? Thank you friends help
The video line follows the cable with the elevator. Car roof camera power in the car to take 220V DC power. The phone is connected directly to the pit.
Q:What is the meaning of the power line of the computer?
---------------------- extended reading ------------ ------ Select the industrial communication cable, first meet the impedance (Z0 = 120Ω) match, and then according to the specific communication rate, transmission distance, wiring environment, laying mode configuration different model specifications
Q:Will the leaking water cause a short wire in the wall?
The specific need to see how many of your home wiring drawings. But with the line to pay attention to, lighting needs more than 1.5 copper wire, socket 2.5 or more, air conditioning need at least 4 square above the line. 1.5 square feet of 50m, 2.5 square meters of 100 meters, 4 square meters of 50 meters. The specific depends on the line layout, it is best to let the electrician to see you, the material can buy their own. Let the electrician look at the actual needs. Water pipes, 40 to 50 meters is enough, pipe fittings need to calculate the appropriate parts, it is recommended to see the water utility.
Q:What is the difference between a fireproof bridge and a galvanized bridge?
4 port belongs to the IDE hard disk interface called the parallel port power interface SATA is a serial port called the serial power interface Some serial hard drive two power interfaces are to buy is the serial power cable
Q:It is not necessary to draw a set of video lines from the monitor interface
Do parts, like car accessories ah, but the requirements of physical mathematics is better. Do not worry about employment
Q:Cable model ZB and ZR What is the difference
Cable tray, cable tray, usually made of steel or aluminum alloy, which is the bottom of the ladder called the ladder bridge, the bottom of the plate called the trough bridge, trough bridge is also called the cable tray Width is generally more than 100mm, and occasionally 75-80mm The maximum width is generally no more than 12m Suitable for factories and other cable more and lay the path of the local concentration of choice Cable trench in the ground production of the channel, usually for the brick cement plaster, suitable for less ground equipment, cable and lay the path of the local concentration of the selection, generally with the ground above the cable bridge used together
