The 257DER2R5SDP is a radial lead ultracapacitor rated for 2.5 VDC with a capacitance of 250.0 F. It has a maximum continuous current of 48.1 A, an equivalent series resistance of 18 mΩ, and operates within a temperature range of -25°C to +70°C. The component measures 30 mm in diameter and 55 mm in length, with a lead spacing of 10 mm and lead diameter of 1.5 mm. It supports 500,000 charge/discharge cycles with a capacitance change within +30% and ESR under 200% of initial values. Life expectancy at rated voltage and 70°C is 1,000 hours, with leakage current specified at 22 mA after 72 hours at 25°C.
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.
