Cornell Dubilier Electronics Inc. has expanded its line of high performance flat electrolytic capacitors with the NHR series that is 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 Flatpack series of capacitors that have 30 years of proven applications in military and aerospace. The NHR Flatpack technology offers exceedingly long life at high temperature for critical applications that previously have been the domain of wet-tantalum capacitors. Their high-capacitance density at high voltage and temperature solves many of the problems faced by engineers designing circuits for extreme environments. The series is designed to replace large series-parallel banks of wet tantalum capacitors with fewer components, saving our customers valuable space, weight, and cost.
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.
