Double-layer capacitors work in harsh environments

By Heather Hamilton, contributing writer

Vishay Intertechnology, Inc. has released a series of high-voltage ENYCAP electrical double-layer energy storage capacitors designed to harvest energy and provide backup power for applications in harsh environments. With a useful life of 2,000 hours at 85°C, the Vishay BCcomponents ENYCAP devices are one of the first in the industry with a useful life that is double that of standard electrical double-layer capacitors. This provides maintenance-free operation as well as greater design flexibility.

The EDLC-HV ENYCAP capacitors also boast a maximum rated voltage of 3.0 V, which makes them suited for a variety of industrial, renewable energy, and automotive applications, including smart meters, handheld electronics, robotics, solar panels, E-latch door systems, and emergency lighting.

These capacitors come in eight small case sizes, which range from 16 × 20 mm to 18 × 40 mm, with a high power density to 4.1 Wh/kg. Capacitance values range from 20 F to 60 F. They’re RoHs-compliant, feature rapid charge and discharge performance, and are available in through-hole versions.

The 230 EDLC-HV ENYCAP capacitors are available now in samples and production quantities. For larger quantities, lead time is six weeks. Prices with U.S. delivery ranges from $1.70 to $3.40 per piece. Check for distributor stock here.
