Cornell Dubilier Type HHT Aluminum Electrolytic Capacitors feature a glass-to-metal seal to prevent dry-out of the capacitor electrolyte and offer long life and rugged construction for high temperature environments.
HHT capacitors are rated for a 2,000 hours operating life at 175ºC, rated voltage. The HHT capacitors outperform competitive technologies in a 5,000 hour test at 150ºC and full rated ripple current. This level of performance makes the HHT series 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.
