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.
Our series of strong products of capacitors can be divided into
below types:
★ Ceramic Disc Capacitor( low and high voltage, Y1/Y2 safety )
