Vishay Intertechnology, Inc. has introduced a new series of ruggedized ENYCAP™ electrical double-layer energy storage capacitors for energy harvesting and power backup applications in harsh, high humidity environments. Vishay BCcomponents 225 EDLC-R ENYCAPcapacitors are the industry’s first to offer useful life of 2000 hours at +85 °C and meet the highest class of moisture resistance: the biased 85/85 1000-hour test.

The long useful life of the devices released today is double that of standard electrical double-layer capacitors, enabling maintenance-free operation and greater design flexibility. Their high humidity resistivity allows for use in a wide range of industrial, renewable energy and automotive applications, including smart meters, handheld electronics, robotics, solar panels, E-latch door systems and emergency lighting.
Available in eight small case sizes ranging from 16 mm by 20 mm to 18 mm by 40 mm, 225 EDLC-R ENYCAP capacitors offer high power density to 4.1 Wh/kg, capacitance values from 20 F to 60 F and a maximum rated voltage of 2.7 V. The RoHS-compliant devices feature rapid charge and discharge performance and are available in through-hole versions.
Samples and production quantities of the 225 EDLC-R ENYCAP capacitors are available now, with lead times of six weeks for larger quantities. Pricing for U.S. delivery only ranges from $1.80 to $3.60 per piece.
