Hybrid energy storage capacitors offer best available energy / volume ratings

Vishay's new 196HVC ENYCAP Series of hybrid energy storage capacitors are now available from TTIEurope. The devices offer electronics designers the best energy / volume ratings currently available on the market, as well as enhanced charge and discharge performance for energy harvesting and power line backup applications, says the company. The ENYCAP Series of polarized storage capacitors offers high capacity and high energy density and is an alternative product to rechargeable backup batteries. The capacitors have a very long self-discharge period of several months and due to specialised proprietary technology, they require no cell balancing. The ENYCAP Series provides soft charging of <1A and low leakage current after 24 hours (IL) from 0.03mA to 0.24mA. For design flexibility, the 196HVC ENYCAP Series is available in various configurations, including surface-mount flat, stacked through-hole, and lay flat with wire and connectors. Voltage ratings are also flexible with 1.4V (single cell) versions and 2.8V, 4.2V, 5.6V, 7V and 8.4V multiple cell models. The low profile (2.5mm) design of these new Vishay hybrid energy storage capacitors fits compact and portable designs. Suitable applications include power backup for memory controllers, flash backup, RAID systems, SRAM, DRAM; power failure and write cache protection for enterprise SSD and HDD; backup power for industrial PCs and controls; storage devices for energy harvesting; emergency light and micro UPS power sources; and burst power support for flash lights and wireless transmitters, says the company.
