A new series of 3.0V ruggedised ENYCA electrical double-layer energy storage capacitors for energy harvesting and power backup applications in harsh, high humidity environments has been introduced by Visay Intertechnology.

Vishay BCcomponents 235 EDLC-HVR ENYCAP capacitors offer useful life of 2000 hours at +85°C and meet the highest class of moisture resistance: the biased 85°C / 85% RH 1500-hour test.

The long useful life of the devices 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 15 small case sizes ranging from 10mm by 20mm to 18mm by 40mm, 235 EDLC-HVR ENYCAP capacitors offer high power density and capacitance values from 5 F to 60 F.

The RoHS-compliant devices feature rapid charge and discharge performance and are available in through-hole versions.

Samples and production quantities of the 235 EDLC-HVR ENYCAP capacitors are available now, with lead times of six weeks for larger quantities.
