New high voltage energy storage capacitors for harsh environments

Vishay Intertechnology has a new series of high voltage ENYCAP electrical double-layer energy storage capacitors for energy harvesting and power backup applications in harsh environments. The 230 EDLC-HV ENYCAP capacitors are among the industry's first to provide a useful life of 2,000 hours at +85C and a maximum rated voltage of 3V. The long useful life of the devices is twice that of standard electrical double-layer capacitors, providing maintenance-free operation and greater design flexibility. With their high rated voltage, the capacitors can be used in a broad range of industrial, renewable energy, and automotive applications, including smart meters, handheld electronics, robotics, E-latch door systems, solar panels, and emergency lighting. Available in eight small case sizes ranging from 16mm x 20mm to 18mm x 40mm, the capacitors offer high power density to 4.1Wh/kg and capacitance values from 20F to 60F. The RoHS-compliant devices offer rapid charge and discharge performance and are provided in through-hole versions.
