MOV Metal Oxide Varistor 14D471K 20D471K Varistor Voltage 470 (423～517)
Metal Oxide Varistor (MOV) as one nonlinear resistance element is mainly made of zinc oxide (ZnO), which has very high surge capacity and big non-linear coefficient. Below the threshold voltage, its resistance is very high, nearly no current flows through, but above the threshold voltage, the resistance reduce sharply, huge current can be discharged. Due to this characteristic, varistor as a protection component in electronic and electrical equipment can absorb abnormal over-voltage and lightning surge.
ETOPMAY varistor is with High Surge Current Density, Low Clamping Voltage, and Good Surge Capacity. It can also be customized as required.

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.
