Long-life capacitor from Cornell Dubilier

Cornell Dubilier Electronics Inc. (CDE) has introduced a 15yr long-life Type EDL electronic double-layer capacitor specifically for use in battery backup applications when battery replacement is necessary. Applications include cellphones, solar battery back-up, small motor starters, gaming machines, real-time clock battery back-up and remote reading utility meters.

The Type EDL capacitor is available in horizontal and vertical radial-leaded stacked coin configurations, a cylindrical case with radial leads and a surface-mount package. The capacitors offer capacitance values from 0.22F to 70F with a voltage range of 2.1Vdc to 5.5Vdc depending on the capacitance rating. The EDL provides unlimited charging and discharging capability and extends battery life up to 1.6 times longer, said the company.

Typical price range is 46.4 cents to $5 each. Delivery is from stock to 13 weeks from authorized CDE distributors.
