CA55 Series Conductive Polymer Electrolytic Chip Tantalum Capacitor 470uF 6.3V 20% 7343
Brief Introduction
Conductive polymer electrolyte chip aluminum electrolytic capacitor uses aluminum foil as the capacitor matrix and conductive polymer polymerization layer as the cathode electrolyte. It is made by stacking and welding multiple layers of aluminum foil and encapsulated with epoxy resin. Due to the excellent conductive property of conductive polymer and its good adhesion with medium layer, it has ultra-low ESR and excellent temperature performance due to its multi-layer parallel structure.
Application
Communications, 5G IOT, consumer electronics, automobile,Security Monitoring,Instruments and Meters, medical equipments and etc.
Test Condition
Ambient temperature:25℃±5℃, relative humidity :≤80% RH .The capacitance, loss and ESR of the capacitor are measured in series under 2.0V bias voltage, in which the ESR test frequency is 100kHz, the capacitance and loss test frequency is 120Hz, and the leakage current is measured when the capacitor is charged with rated voltage for 5min.
Conduct
Test and experiment, in order to make the test results not problems, it is necessary to will test the product after fully discharge.This product is a polar components, testing or when using it is strictly prohibited to will is negative pick back, in order to avoid performance failure.

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.
