Electrolytic capacitors now include voltage up to 400 V dc
Cornell Dubilier Electronics, Inc. (CDE) announced that it has expanded its signature series of 380LX and 381LX aluminum electrolytic capacitors to include voltages up to 600 Vdc. The new ratings are designed to serve the company’s industrial electronics customers who continue to push the application boundaries for these components into higher voltages. The 380LX and […]
Snap-in aluminum electrolytic caps handle 600 Vdc
The 380LX and 381LX series of aluminum electrolytic capacitors now include voltages up to 600 Vdc. The new ratings are designed to serve industrial electronics customers who continue to push the application boundaries for these components into higher voltages. The 380LX and 381LX snap-in series are among the industry’s top performers with a published load […]
Putting supercapacitors to work
There are a variety of modern applications in which supercapacitors are better candidates than either batteries or ordinary capacitors. George Wundsam, Cornell Dubilier Supercapacitors are not new. First developed in the 1950s, commercial versions were marketed over 40 years ago. At that time, supercapacitors were certainly not on a fast track to practical application. They […]
High-current ac harmonic filter capacitors offer built-in fail-safe protection
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, […]
