The 255DCN5R5Q is a 2.5 F, 5.5 V ultracapacitor for high-power applications such as battery backup and pulse power, with a snap-in radial package measuring 21.5 mm in length, 23.5 mm in height, and 11 mm in thickness, and a lead spacing of 15.3 mm. It has a maximum ESR of 220 mΩ at 1 kHz and a leakage current of 2.81 mA at 72 hours and 25°C. The device operates from -40°C to +60°C, supports 500,000 charge/discharge cycles, and maintains capacitance within +30% and ESR within 200% of initial values after 1,000 hours at 60°C with rated voltage applied. It complies with IEC 62391 and is designed for board mounting.
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. Choose from board mountable coin type and radial form factors or work with us to develop higher voltage custom modules with active or passive balancing.
