New Yorker Electronics has released a new ruggedized capacitor with an extraordinary shelf-life and built for applications demanding very high-performance under all operating conditions. The new Cornell Dubilier Electronics HHT Series of Ruggedized Axial-Lead Aluminum Electrolytic Capacitors are designed to endure the rigors of extreme industrial and aerospace applications.
The HHT is the only axial-lead electrolytic featuring a glass-to-metal seal to prevent dry out of the capacitor electrolyte. Shelf life is an extraordinary ten years and operational rated life is 2,000 hours at rated voltage and at +175°C. At 150°C and full-rated voltage, HHT capacitors outperform competitive technologies in a 5,000-hour test with ripple currents of up to 10 Arms. This level of performance makes the HHT an excellent match for high-stress applications in military, aerospace, down-hole and off-road transportation applications. Nine values are offered, from 470µF to 4,700µF, with ratings from 16Vdc to 40Vdc.
The CDE HHT Series is the only aluminum electrolytic capacitor available in the market with +175°C performance. This is usually the domain of the considerably more expensive wet tantalum technology.
The reason is the HHT’s glass-to-metal seal. Without the seal, high temperatures will cause conventional electrolytics to lose electrolyte over time. This causes a drop in capacitance and an increase in ESR. With capacitance stability at high temperature, low leakage current with very competitive ESR and ripple current specifications, these devices provide new options for mission-critical applications. Like other CDE capacitors, the HHT Series is subject to the industry’s most rigorous dynamic testing. The 20g vibration testing follows procedures outlined in MIL-STD-202, method 204.
HHT case diameter is a low-profile 20mm for all values, with length varying from 37 to 53mm depending on values. The axial lead wires are a substantial 18 AWG. They are RoHS compliant and free of conflict materials.
