Electrolytics rated for ultra-long life in LED lighting

February 03, 2016 // By Graham Prophet
CapXon’s LE series of electrolytic capacitors promises high reliability and ultra-long life in LED lighting applications. The products operate over an extended temperature range of -40 to +105˚C making them suitable for LED drivers powering outdoor lighting applications.

This series offers a longer life alternative to the same supplier’s FL series used in electronic lighting ballasts and energy-saving luminaires. At 105˚C ambient temperatures, the capacitors have lifetimes of 12,000 hours for 6.3 x 11 mm, 8 x 9 mm and 10 x 9 mm case sizes, 15,000 hours for 8 x 11.5 mm and 10 x 12.5 mm and 20,000 hours for case sizes 10 x 16 mm or larger. The radial mount series is available in industry standard capacitance values ranging from 1 to 68 µF, with rated voltages of 160V, 200V, 250V, 400V and 450 Vdc. Ripple current ratings of up to 1,300 mA (rms at 105˚C at 100 kHz) are available, and maximum low temperature impedance ratios range from 8 to 12 depending upon the capacitor voltage rating.
