HL Series Electric Double Layer Capacitors

Panasonic's HL series of small size electric double layer capacitors with a radial lead type

Image of Panasonic's HL Series Electric Double Layer Capacitors Panasonic extends its HL series electric double layer capacitors (EDLCs), which offers low resistance combined with guaranteed long life over a wide temperature range, from -40°C to +85°C. Panasonic HL series gold capacitors are wound radial lead type devices which achieve far better capacitance compared to aluminum electrolytic capacitors (up to 1,000 times greater) and superior backup performance. Additional benefits of rapid charge and discharge cycles (over 500,000 times) and exceptional aging characteristics make Panasonic HL series EDLC capacitors ideal for applications, such as 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 2.5 F, 4.0 F, and 7.5 F to the existing 50 F and 100 F parts, all rated at 2.7 VDC. These EDLCs maintain their capacitance and internal resistance without drifting at low temperatures, as opposed to other products available where the capacitance and internal resistance values may change by ±30% and up to 7 times, respectively, from initial measured values. 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. For power backup applications where aging characteristics cause a rise in internal resistance and rapid decline in capacitance, EDLC capacitors are especially beneficial. Due to the unique electrolyte used in the Panasonic parts, such aging effects are mitigated, in effect leading to part count reduction.

The extension of the 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. The new leakage-safe electrolyte which does not produce any hydrogen cyanide gives Panasonic an edge in terms of extended temperature range and responsible environmental stewardship.
