The 226DER2R5SKV is a radial lead ultracapacitor with a capacitance of 22.0 F and a rated voltage of 2.5 VDC, designed for high-power pulse applications such as battery backup and DC/DC conversion. It has a case diameter of 16 mm and a height of 25 mm, with a lead spacing of 7.5 mm and lead diameter of 0.8 mm. The part operates within a temperature range of -25°C to +70°C and supports 500,000 charge/discharge cycles with a capacitance change of ≤+30% and ESR ≤200% of initial values. Maximum continuous current is 8.59 A, ESR is 60 mΩ at 1 kHz, and volumetric energy density is 3.7993 Wh/L. Life expectancy is rated at 1,000 hours at 70°C and rated voltage, with leakage current specified per standard part listing.
Also known as ultracapacitors, double-layer capacitors or electro-chemical double layer (EDLCs). Whatever you call them, CDE likely has what you need, offering a comprehensive range of capacitance values and voltages. Our technology is used in a wide variety of applications from battery backup in smart meters to regenerative braking.
