New ruggedised energy storage capacitors for long life and high moisture resistance

16-05-2018 | Vishay | Passives

Vishay Intertechnology has introduced a new series of ruggedised ENYCAP electrical double-layer energy storage capacitors for energy harvesting and power backup applications in harsh, high humidity environments. Vishay BCcomponents 225 EDLC-R ENYCAP capacitors offer a useful life of 2000 hours at +85C and meet the highest class of moisture resistance: the biased 85/85 1000-hour test. The long useful life of the devices is double that of standard electrical double-layer capacitors, allowing maintenance-free operation and excellent design flexibility. Their high humidity resistivity provides for use in a broad range of industrial, renewable energy, and automotive applications, including handheld electronics, robotics, smart meters, solar panels, E-latch door systems, and emergency lighting. Available in eight small case sizes ranging from 16mm x 20mm to 18mm x 40mm, the capacitors provide high power density to 4.1Wh/kg, capacitance values from 20F to 60F, and a maximum rated voltage of 2.7V. The RoHS-compliant devices feature rapid charge and discharge performance and are available in through-hole versions.
