Knowles Precision Units has introduced the provision of its newest Electrical Double Layer Capacitor (EDLC), or supercapacitor, modules. Primarily based on Knowles’ Cornell Dubilier model DGH and DSF Collection supercapacitors, these capacitors use a three-cell package deal for increased working voltages and printed circuit board area financial savings.
Knowles acquired Cornell Dubilier in 2023 to broaden its providing of movie, electrolytic and mica capacitors. Supercapacitors present very quick energy discharge that can’t be matched by standard capacitors or batteries, making it potential 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 power storage purposes, in keeping with the corporate.
The brand new supercapacitors supply a notable bounce in voltage ranking over typical radial-mount supercapacitors, as much as 9.0 WVDC. A key characteristic of the brand new DGH and DSF Collection merchandise is the three-cell radial-leaded package deal. In comparison with single- or dual-cell supercapacitors, the compact design saves area and permits for a lot increased working voltages. Each sequence embody capacitance values from 0.33 to five Farads. A number of units might be banked for even increased capacitance or voltage.
From a efficiency standpoint, each sequence supply excessive power density and intensely low self-discharge charges. Each sequence 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 sequence resistance (ESR) minimizes power loss for top effectivity.
These supercapacitors are designed to resist over 500,000 cost/discharge cycles. Working life is anticipated to be as much as 10 years.
All gadgets are in distributor inventory.
