Cornell Dubilier Expands Flat Aluminum Electrolytic Capacitor Line, which now withstand 150 °C and 80g Vibration
With rated load life of 3,000 hours at 150 °C, the series is poised to replace costly banks of wet tantalum capacitors.
LIBERTY, S.C. (PRWEB) DECEMBER 09, 2020 - Cornell Dubilier Electronics, Inc. (CDE) has expanded its line of high performance flat electrolytic capacitors with the NHR Series. Able to withstand operating temperatures from –55 °C to 150 °C, NHR capacitors are constructed with rectangular stainless-steel cases and laser-welded covers that prevent dry-out. These capacitors have a 3,000-hour life at full-rated conditions and withstand up to 80g vibration to meet the most demanding military, aerospace, industrial, and down-hole applications.
Type NHR is a spin-off of the company’s Flatpack series that has been proven in military and aerospace applications for nearly 30 years. “Our NHR Flatpack technology offers exceedingly long life at high temperature for critical applications that previously have been the domain of wet-tantalum capacitors,” said Mario DiPietro, Product Manager for Cornell Dubilier. “Their high-capacitance density at high voltage and temperature solves many of the problems faced by engineers designing circuits for extreme environments,” continued DiPietro. The company claims it has had considerable success in helping its customers replace large series-parallel banks of wet tantalum capacitors with fewer components, saving them valuable space, weight and cost.
Components within the NHR series are available from 75 Vdc through 300 Vdc with capacitance values ranging from 60 µF to 960 µF. There are four case lengths available in 0.5” increments from 1.5” to 3.0”. All cases measure 0.5” thin by 1.0” wide. The series has a load life of 3,000 hours at 150°C, withstands up to 50g vibration on the three largest cases, and up to 80g on the smallest case size. The series has been tested for altitudes up to 80,000 ft.
Potential applications include any high-performance circuits that require large capacitance bulk storage and filtering at high temperature. These include power supplies and inverters for avionics, military electronics, and such energy industry applications as down-hole recording devices.
