Axial-lead aluminum electrolytic capacitors for military and aerospace introduced by Cornell Dubilier
LIBERTY, S.C. – Cornell Dubilier Electronics Inc. is introducing a line of axial-lead aluminum electrolytic capacitors for military, aerospace, down-hole oil exploration, and off-road transportation power electronics applications that demand high-performance under all operating conditions.
The HHT features a glass-to-metal seal to prevent dry-out of the capacitor electrolyte. Shelf life is 10 years and operational rated life is 2,000 hours at rated voltage and 175 degrees Celsius.
At 150 C and full-rated voltage, HHT capacitors outperform competitive technologies in a 5,000-hour test with ripple currents as strong as 10 Arms. Nine values are offered, from 470 to 4,700 microfarads, with ratings from 16 to 40 volts DC.
Without the glass 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 and competitive ESR and ripple current specifications, these devices provide new options for mission-critical applications. The HHT series is subject to dynamic testing per MIL-STD-202, method 204.
HHT case diameter is 20 millimeters for all values, with length varying from 37 to 53 millimeters depending on values. The axial lead wires are 18 AWG. They are RoHS compliant and free of conflict materials.
