Capacitors offer best energy/volume plus point
The 196HVC ENYCAP Series of hybrid energy storage capacitors by Vishay is now available in Europe at TTI. 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.
These polarised storage capacitors offer high capacity and high energy density and are an alternative product to rechargeable backup batteries. The capacitors have a very long self-discharge period of several months and they require no cell balancing. The ENYCAP Series provides soft charging of less than 1A and low leakage current after 24 hours (IL) from 0.03 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 2.8, 4.2, 5.6, 7.0 and 8.4V multiple cell models. The low profile (2.5mm) design of these 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.
