Application

Varistors are mainly used to limit harmful atmospheric overvoltages and operating overvoltages and can effectively protect a system or equipment:

In the electric power industry, pressure sensitive materials are often used to make arrester valve plates. The high voltage insulator made of zinc oxide pressure sensitive material has not only insulating effect but also transient overvoltage protection.
In the electronic circuit, it has the functions of overvoltage protection, lightning protection, surge current suppression, peak pulse absorption, amplitude limiting, high voltage arc extinction, noise elimination and semiconductor device protection.

It is mainly used in semiconductor protection, surge protection in home appliances, communication and measuring devices.

FAQ Of Topmay Capacitor

1) Can I have a free sample to test ?
Yes, we could provide free samples to test and check quality. Freight cost is collected.

2) What is the lead time?
Sample needs about 7~10 working days prepared; mass production average time takes 15-20 working days

3) Do you have any MOQ limit?
Yes. But it depends on product. Normally MOQ is 2K~10Kpcs

4) How about price terms?

We do FOBSHENZHEN if order amount is more than 5000USD. Less than that, it is EXWSHENZHEN and we do not undertake local charge.

5) What information should I let you know if I want to get a quotation?

Basically for capacitor, it requires to know detailed capacitance and voltage. If you have more information, such as type, product photo for reference, you could kindly provide too.
