Charged EVs | Knowles Precision Devices introduces supercapacitors that operate at up to 9 WVDC

Knowles Precision Gadgets has introduced the provision of its newest Electrical Double Layer Capacitor (EDLC), or supercapacitor, modules. Based mostly on Knowles’ Cornell Dubilier model DGH and DSF Series supercapacitors, these capacitors use a three-cell bundle for increased working voltages and printed circuit board house financial savings.

Knowles acquired Cornell Dubilier in 2023 to increase its providing of movie, electrolytic and mica capacitors. Supercapacitors present very quick energy discharge that can not be matched by standard capacitors or batteries, making it doable for them to help transient energy interruptions, complement batteries, and even be used rather than batteries in some purposes. These supercapacitors are perfect for EV transportation energy and lots of different vitality storage purposes, in line with the corporate.

The brand new supercapacitors supply a notable leap in voltage score over typical radial-mount supercapacitors, as much as 9.0 WVDC. A key function of the brand new DGH and DSF Sequence merchandise is the three-cell radial-leaded bundle. In comparison with single- or dual-cell supercapacitors, the compact design saves house and permits for a lot increased working voltages. Each collection embrace capacitance values from 0.33 to five Farads. A number of units may be banked for even increased capacitance or voltage.

From a efficiency standpoint, each collection supply excessive vitality density and intensely low self-discharge charges. Each collection are additionally tolerant of wide-ranging operational environments, with working temperature ranges from -40° C to +65° C for DGH 8.1 V/DSF 9.0 V and -40° C to +85° C for DGH 6.9 V/DSF 7.5 V. Low equal collection resistance (ESR) minimizes vitality loss for prime effectivity.

These supercapacitors are designed to face up to over 500,000 cost/discharge cycles. Working life is predicted to be as much as 10 years.

All objects are in distributor inventory.
