The new line of axial-lead aluminum electrolytic capacitors from Cornell Dubilier Electronics, Inc. (Liberty, SC) are suited for applications demanding very high-performance under all operating conditions. According to the company, the ruggedized HHT is the only axial-lead electrolytic featuring a glass-to-metal seal to prevent dry-out of the capacitor electrolyte. Shelf life is 10 years and operational rated life is 2000 hours at rated voltage and +175°C (347°F). At 150°C (302°F) and full-rated voltage, the company claims HHT capacitors outperform competitive technologies in a 5000-hour test with ripple currents of up to 10 Arms. This level of performance makes the HHT suitable for high-stress applications in military, aerospace, down-hole and off-road transportation applications.
