Established in 1998, China Dianshen Electric Co., Ltd. is a professional panasonic capacitor manufacturer and panasonic capacitors design of electric and electronic products. Together with the European 'CE', 'CCC', GS/EMC/LICE/UL/CSA, and 'CB' (IEC) certification that we have received for various series. Currently, our custom panasonic capacitor product series are being exported worldwide. Our pursuit of first-rate quality, competitive and cheap panasonic capacitors prices and comprehensive after-sales services offers both potential and long-standing clients confidence in our company.

In order to fulfil increasing demand, this range has been designed specifically for applications where long life, high temperature, low ESR, low impedance and high ripple current are required. For example, the secondary circuit of a switching Power Supply. ASUS actually uses the white shaded part to indicate the positive lead on their PCBs, which is quite confusing. Occasionally there may be an error in the marking of the PCB also. So the best thing to do when replacing capacitors is to trust the way the original capacitors were positioned on the board and not the PCB.
Low impedance, low ESR and high permissible ripple current
40-70% lower ESR than existing standard FC series e.g. 12.5 x 35 size : 0.012 ohm max at 100 kHz
Approximately 1.5 times higher ripple current available, compared to existing standard FC series e.g. 16 x 25 size : 3820 mA rms at 100 kHz
Long life – 2000 to 7000 hours at 105°C
1.5 times longer life time guarantee compared with existing FC series
Approximately 30% smaller case size than standard FC series
Fully RoHS compliant, PVC and Lead (Pb) free.

Radial capacitors have two leads which stick out from the bottom of the capacitor. They are a different configuration to axial capacitors in that sense because axial have one lead that sticks out from either end. Since Polymer capacitors came into use it was necessary to find a term to differentiate between the older technology of using a liquid electrolyte and the newer of using polymer crystals. A typical reference to capacitors with liquid electrolyte might call them wet electrolytics. Both the Panasonic FC in the first photo and the Rubycon MCZ in the second photo are wet electrolytics. Radial Electrolytic capacitors have polarity and therefore it is important to solder them in with the correct polarity. Failure to do so and they vent (bulge at the top) after some minutes of operation. Positions for capacitors are marked with a circle that has one part shaded white. This marks the negative lead position. The capacitors also all have a stripe down one side. This marks the negative lead. So you need to line up those marks. Not all PCBs follow this rule though.
