EDLC capacitors with smaller cells offer longer life and higher performance
The HL Series gold capacitors are wound radial lead type devices, which provide higher performance over aluminium electrolytic capacitors and superior charge and discharge performance compared with secondary batteries. The capacitors support of rapid charge and discharge cycles with over 500,000 cycles and are aimed at backup power supplies for servers and storage devices, solar-powered products, smart grid solutions, and driver-assist for motors and actuators in a variety of markets.
The extension of the HL Series adds nominal capacitance values of 2.5µF, 4.5µF and 7.5µF to the existing 50µF and 100µF parts, all rated at 2.7VDC. These ELDCs are guaranteed to maintain their capacitance and internal resistance without drifting at low temperatures, as opposed to other devices where the capacitance and internal resistance values may change by ± 30% and up to 7 times respectively from initial measured values.
The smaller size HL Series devices are guaranteed for a life of 2,000 hours at +70 °C but can achieve 1,000 hours at 85 °C with voltage derating. The electrolyte used in the EDLC capacitors reduces ageing effects such as a rise in internal resistance and rapid decline in capacitance.
“The extension of our HL Series within a year of its original launch testifies to the need for reliable, endurable and scalable backup solutions offering significant cost and space-saving benefits,” said Andreas Lapucha, Product Marketing Manager Capacitors at Panasonic. “The new leakage-safe electrolyte does not produce any Hydrogen Cyanide which gives us an edge over market competition in terms of extended temperature range and responsible environmental stewardship.”
