Vishay Intertechnology, Inc. on the 10th of May 2018 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. They are industry’s first capacitors that offer useful life of 2000 hours at +85 °C and also meet the highest class of moisture resistance: the biased 85 / 85 1000-hour test.

The long useful life of the devices mentioned earlier is twice as good as life of standard electrical double-layer capacitors, that enables maintenance-free operation and greater design flexibility. Their high resistance to humidity allows them to be used 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.

ENYCAP capacitors offer high power density to 4.1 Wh/kg, capacitance values from 20F to 60F, and a maximum rated voltage of 2.7 V.
