Electrolytic capacitors promise ultra-long life for LED lighting
Available in the UK from Components Bureau, the products operate across 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 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 68µF, with rated voltages of 160 V, 200 V, 250 V, 400 V 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.
The LE series capacitors are available now, with low minimum order quantities. Samples are available upon request.
