3. General Specifications
Rate discharge Cap. F(25℃) ( ΔV＝2.16V-1.35V) | Cap. Tolerance (25℃) | Rated Voltage (V) | Operating Temp. (Top) | ESR (1KHz) (mΩ) |
| 500 | 0%~+30% | 2.7 | -40~70℃ | 10 |
4.Product Structure
This capacitor is on the basis of theory of double layer capacitor. Internal using activated carbon as positive and negative electrodes, separated by electrolyte and diaphragm between two electrodes, To seal using aluminum shell and rubber plug. The lead terminals are on the same side of the capacitor.

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.
