Cornell Dubilier announces its new, patented, PCD series of high current, AC harmonic filter capacitors offering dual, built-in, fail-safe protection systems, one at each end of the capacitor. Similar capacitors in this category have one open-circuit pressure device located under the top cover that requires the capacitor to be mounted from its bottom stud. With […]

Illinois Capacitor line now part of CDE.com
Cornell Dubilier has brought its Illinois Capacitor brand capacitors to cde.com. Now engineers can view the entire portfolio of CDE and IC capacitors for power electronics applications on one site. This includes such specialized products as IC’s supercapacitors, conduction-cooled (high density resonant) capacitors, rechargeable coin cell batteries, and other new additions. CDE’s updated parametric search […]
DC link capacitors excel at handling humidity, vibration, and thermal cycles
The CDE BLH series of dc Link capacitors have been designed and tested to exceed the industry’s most stringent requirements for high humidity, vibration testing and thermal cycling. The Temperature, Humidity at Bias (THB) test exposes parts to the harsh conditions of 85°C at 85% relative humidity with rated voltage applied. This demanding test simulates […]
Super-caps cover 0.5 to 600-F range at up to 3.0 V
The DGH 2.7-V and DSF 3.0-V series supercapacitors (aka EDLCs or ultracapacitors) are used to supplement rechargeable batteries or as replacements for batteries in a diverse range of applications. These new components add powerful options for engineers. According to Brendan Andrews, Cornell Dubilier Business Unit Manager, “Our technology is used in a wide variety of […]
85/85 THB-rated AC filter capacitors designed for harsh environments
Designed for harsh environments, Cornell Dubilier’s new ALH series of AC-rated filter capacitors offer 50% greater life than competitive 85/85 THB-rated film capacitors. The Temperature, Humidity at Bias (THB) test exposes parts to the harsh conditions of 85 °C at 85% relative humidity with rated voltage applied. CDE’s testing has been validated for 1,500 hours, […]
AC filter capacitors optimized for harsh environments
The new ALH series of ac-rated filter capacitors offer 50% greater life than competitive 85/85 THB-rated film capacitors. The Temperature, Humidity at Bias (THB) test exposes parts to the harsh conditions of 85°C at 85% relative humidity with rated voltage applied. CDE’s testing has been validated for 1,500 hours, while competitors validate their series for […]
Selecting dc-link capacitors for inverters
One key factor: Determining the nuances of how capacitors handle expected ripple currents. Sam G. Parler, Jr., P.E. Cornell Dubilier Examine a dc link capacitor’s ac ripple current and you’ll realize it arises from two main contributors: the incoming current from the energy source and the current drawn by the inverter. Of course, capacitors cannot […]
Hybrid lithium-ion supercaps deliver up to 220 F at 3.8 V
Cornell Dubilier Electronics introduces two new series of Hybrid LIC Supercapacitors in response to the growing need for ultra-high capacitance values at higher operating voltages. The new VMF and VPF Series operate at 3.8 WVDC with capacitance values up to 220 Farads. The higher voltage results in increased energy density. With nearly eight times the energy density and a […]
And the LEAP Gold for Power Electronics goes to…Cornell Dubilier
The winners of the 2020 LEAP Awards (Leadership in Engineering Achievement Program) were announced last week in a digital ceremony, with products across 12 categories, including embedded computing, power electronics, and test and measurement. Critical to LEAP’s success is the involvement of the engineering community. No one at WTWH Media selected the winners. Instead, our […]
Supercapacitors operate at 3 and 6 V
A new series of higher-voltage and high-energy-density supercapacitors, called DSF Supercapacitors, offer a notable jump in voltage rating over typical supercapacitors to 3.0 WVdc for a single component and 6.0 WVdc for a dual-pack device. This higher voltage spec results in greater energy densities, which in turn saves space and may reduce the number of […]
