The 257DCN2R7SDP is a 250 F, 2.7 V ultracapacitor designed for high pulse power and battery life extension, with a snap-in mount and dimensions of 30 mm x 55 mm x 10 mm. It has a maximum ESR of 13 mΩ at 1 kHz, stores 253.125 mWh of energy, and operates within -40°C to +60°C. The part supports 500,000 charge/discharge cycles, with capacitance change limited to +30% of initial value and ESR below 200% of initial specification after life testing. Lead spacing is 10 mm. The capacitor meets IEC 62391 standards for reliability and performance.
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.
