New high ripple current hybrid capacitors target high-reliability applications

Panasonic Automotive & Industrial Systems has introduced a new series of conductive polymer hybrid aluminium electrolytic capacitors with 45% higher ripple current, suiting the devices to high-reliability and other applications which require low leakage, high capacitance and high stability. The 125C Hybrid Capacitors in 25 and 35V now feature a ripple current of up to 2900mArms. This is the best performance available for such small devices and approaches the ripple current performance of solid polymer devices (10.2mm maximum height) but with the many advantages of the Hybrid Polymer Capacitor technology - low leakage current, high capacitance, low power consumption, stable operation and the ability to withstand test environmental conditions (85C/85%/2000 hour RH), says the company. The capacitance range is 10µF to 330µF and the devices feature a high-withstand voltage (25V to 63V) and low leakage current (0.01 CV or 3µF). Endurance is 4000 hours at 125degC, the longest endurance in the industry by each case size (C, D, D8, F & G). Melanie Raimann, European product manager for polymer capacitors, Panasonic, said: “With an operating temperature range of -55C to +125C, these AEC-Q200 qualified, RoHS-compliant parts target high reliability applications including automotive, base stations, industrial equipment, DC-DC converter, power supplies. Vibration-proof resistant devices are available upon request for can sizes of greater than 8mm in diameter.”
