Q:What are the main parameters of inductance?

There are five important parameters of inductance: inductance, allowable deviation, quality factor, distributed capacitance and rated current

Q:The value of the inductance is determined by what

The quality factor of the inductor is related to the DC resistance of the coil conductor, the dielectric loss of the coil frame, and the loss caused by the iron core and the shield.

Q:How to choose the high quality inductor?

So in the selection of inductors, we have to pay attention to it: first, the higher the value of Q.

Q:Using a multimeter to check whether the output voltage, and the rated output voltage line adapter nominal, can allow for 5% error

if possible, can be appropriate resistance as a false load, it can be generally choose to fake the load resistance

Q:What is the difference between a mobile power supply and a power adapter?

Similar SSYMB brand, there are two kinds of charging methods: one is charged by USB cable; one is charged by the power adapter.

Q:Is the inductor inductor

However, charged straight conductor inductance is small, the magnetic field generated by the strong, so the actual reactor is conducting wire into a solenoid, said hollow reactor; sometimes in order to make the solenoid has larger inductance, then inserted into the core in the solenoid, said iron core reactor.

Q:What is a power adapter, what is the use of

The power adapter (Power adapter) is the power supply equipment transform small portable electronic equipment and electronic appliances,

Q:What is the inductance

The skeleton is usually made of plastic, bakelite, ceramics, can be made into different shapes according to actual needs

Q:How to determine whether the computer adapter is available

Today, there is a typhoon, the home of electricity is not stable, there will be no electricity for a while, and then I charge the laptop in the process, the computer did not boot

Q:Laptop power adapter are AC-DC dual-use

The power adapter (Power adapter) is the power supply equipment transform small portable electronic equipment and electronic appliances, generally consists of a shell
