Electrolytic capacitors have high ripple current ratings for solar applications
Distributor Components Bureau introduces the high ripple current, large can, QP and WP series of high reliability electrolytic capacitors, by Jamicon. They provide long-life performance for alternative energy solar PV inverter applications, says the company. The two series are available with a number of capacitance values, with ripple currents as high as 40A (rms) at 85°C and 120Hz.
The WP series offers 2,000 hours life at 85°C, and the QP 2,000 hours life at 105°C, with minimum operating temperatures down to -25°C. The radial capacitors are available in four diameters, 51, 64, 77 and 90mm, and case lengths of 75 to 157mm. High current capable screw connections are made via M5 bolts, (M6 for the 90mm diameter case). Multiple working voltages can be selected in the industry standard values from 160 to 550V DC (500V DC for the WP), capable of withstanding surges voltages of up to 600V DC.
25 industry standard capacitance values (820 to 39,000microF) are offered for the WP series, and 12 (820 to 22,000microF) for the higher temperature rated QP series. The sleeved capacitors are provided with mounting clamps and can be secured via three tabs.
The capacitors are available now, with samples available on request.
