Our Products


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 10 years and operational rated life is 2,000 hours at rated voltage and +175 °C. At +150 °C and full-rated voltage, HHT capacitors outperform competitive technologies in a 5,000 hr 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 470 µF to 4,700 µF, with ratings from 16 Vdc to 40 Vdc.
