Vishay Intertechnology has introduced a new series of ruggedized ENYCAP™ Electrical Double-Layer Capacitors (EDLCs) for energy harvesting and power back-up applications in harsh and humid environments.

The Vishay 225 EDLC-R ENYCAP capacitors are the industry’s first to offer useful life of 2,000 hours at 85°C, and to meet the requirements of the toughest test of moisture resistance: the biased 85°C/85% relative humidity 1,000-hour test.

The long useful life of the devices is double that of standard EDLCs, giving scope for OEMs to design for maintenance-free operation.

Available in eight small case sizes ranging from 16mm x 20mm to 18mm x 40mm, the 225 EDLC-R ENYCAP capacitors offer high power density of as much as 4.1Wh/kg.
