The DGH357Q2R7L is a 350 farad ultracapacitor rated for 2.7 volts DC, designed for high-power applications such as battery backup, pulse power, and energy harvesting. It features a radial leaded package with dimensions of 35 mm in diameter and 60 mm in length, and a lead spacing of 18.4 mm. The part has an ESR of 18.9 mΩ at 1 kHz, stores 354.4 mWh of energy, and supports up to 500,000 charge-discharge cycles. It operates within a temperature range of -40°C to +85°C and meets RoHS compliance and UL 810a recognition. Capacitance tolerance is -10% to +30% at 20°C, and leakage current remains within specified limits under rated operating conditions.
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.
