50 & 100F electric double layer capacitors offer 100k charge cycles

Panasonic’s “Gold Capacitors” offer long life and superior performance over secondary batteries for auxiliary power applications; they have low resistance, ultra-fast charge and discharge cycling that suits backup power supplies for servers and solar applications.

Panasonic Automotive & Industrial Systems Europe’s HL Series Electric Double Layer Capacitors (ELDCs) offer low resistance combined with guaranteed long life over a wide temperature range, down to -40C and extending to +65C. They are wound radial lead type devices, which achieve far better capacitance compared to aluminium electrolytic capacitors (up to 1,000 times greater) and superior charge and discharge performance compared to secondary batteries. The further benefit of a rapid charge and discharge cycles, (over 100,000 times) and exceptional ageing characteristics suit them for for applications such as backup power supplies for servers and storage devices, auxiliary power supplies for solar-powered products including street lighting, and driver-assist for motors and actuators in a variety of markets.


Maximum operating voltage for the HL Series is 2.7 VDC and nominal capacitance ranges from 50 to 100F. These ELDCs are also guaranteed to maintain their capacitance and internal resistance without drifting at low temperatures, as opposed alternatives where capacitance and internal resistance may change up to ± 30% and up to 7 times vs. initial measured values. Both the 50F device and the 100F device in the HL Series are guaranteed for a life of 2,000 hours at +65degC. For power backup applications, ageing characteristics influence the choice of EDLC due to the rise in internal resistance and rapid decline in capacitance. Panasonic asserts that due to the electrolyte used in its parts, these ageing effects are mitigated, as well as delivering significant space-saving.


Mustafa Khan, Product Marketing Manager Capacitors at Panasonic comments: “Our new HL Series raises the bar for reliability, endurance and scalable backup solutions offering opportunities for cost and space-saving. Another reason piquing the market interest for our EDLCs is the use of leakage safe electrolyte material which does not result in release of Hydrogen Cyanide. This market differentiation has won us many environmentally conscientious customers”.
