3. Standard Test Conditions
In general, samples are tested under the condition of standard atmospheric pressure, the 15 ~ 35 ℃ temperature and 25% ~ 75% relative humidity. Samples should be placed more than 1h under the testing temperature. The test conditions of this specification is for standard atmospheric pressure, temperature of 25 + / - 1 ℃, relative humidity for 60-15%.
4. Product Monomer Structure
This product is based on the principle of double-layer capacitor. Activated carbon is used as positive and negative electrode inside. Electrolyte is used to separate the two poles from diaphragm.

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.
