The latest in energy storage technology, supercapacitor modules feature higher operating voltages, compact design, and rapid power discharge for diverse applications.


Knowles Precision Devices, a division of Knowles Corporation, has released its latest electric double-layer capacitor (EDLC) modules, also known as supercapacitor modules, now available through New Yorker Electronics. Based on the DGH and DSF Series from Knowles’ Cornell Dubilier brand, these modules feature a three-cell package for higher operating voltages and space efficiency on printed circuit boards.

The DGH and DSF Series supercapacitors offer rapid power discharge, surpassing conventional capacitors and batteries. They are suitable for various applications, including energy harvesting from solar and wind sources, mechanical actuators, Automated Guided Vehicles (AGV), electric vehicle power, smart utility meters, Internet of Things (IoT) devices, memory backup, and emergency lighting.

These supercapacitors stand out with their higher voltage rating of up to 9.0 WVDC and their unique three-cell radial-leaded package, which allows for higher operating voltages and compact design. The series provides capacitance values ranging from 0.33 to 5 Farads, and multiple devices can be combined for increased capacitance or voltage.

Key features of the DGH and DSF Series include internal cell balancing for optimal performance, high energy density, low self-discharge rates, and tolerance to a wide range of operating temperatures. With low equivalent series resistance (ESR), these supercapacitors are highly efficient and designed to endure over 500,000 charge/discharge cycles, with an expected operating life of up to 10 years.

Some of the key features of the supercapacitors series include:

  • -40°C to 65°C and 85°C Temp Range
  • UL Recognized
  • Capacitance from 0.5F to 600F
  • Voltage to 3.0V

These supercapacitors are suitable for various applications, including battery backups in smart meters, powering handheld scanners and printers, operating electronic valve actuators, supporting green energy systems, and facilitating automated material handling processes.
