Vishay Intertechnology, Inc. today introduced a new series of hybrid ENergY storage capacitors — ENYCAP™ — with low 2.5 mm profiles that feature industry-high energy density of 13 W/g. Offering designers exceptional flexibility and enhanced charge and discharge performance for energy harvesting and power line backup applications, the Vishay BCcomponents 196 HVC ENYCAP series is available with a wide variety of layouts, capacitance values, and voltage ratings.
The ENYCAP series enters the market with up to six cells and capacitance values from 4- to 90-F, with stacked through-hole, surface-mount flat, and lay flat configurations featuring pins, tabs, and connectors. Voltage ratings range from 1.4V up to 8.4V. Its unique technology does not require cell balancing and provides soft charging characteristics < 1A and low leakage current after 24 hours (IL) from 0.03- to 0.24-mA.
