CDE HHT Aluminum Electrolytic Capacitors
CDE’s HHT aluminum electrolytic capacitors deliver stable capacitance for mission-critical applications in high temperature, high vibration environments.
They have rated voltages up to 40 volts DC, ripple current ratings up to 10 amps RMS, and a rated operational life of 2000 hours at temps up 175°C and vibration up to 20g, or 5000 hours at temps up to 150°C. Even my first car, with no A/C, driving down a dirt road in the middle of summer, couldn't take these capacitors down. They're designed for applications like down-hole oil drilling or leading-edge aerospace (or extreme off-highway applications, as the case may be).
HHT capacitors are available from 470 to 4700 microfarads, and a patented glass-to-metal seal prevents the electrolyte from drying out—maintaining capacitance and ESR over the life of the capacitor at a considerably lower cost than the wet-tantalum alternative.
