In this video series from TTI, we showcase new products and highlight their specs.

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.  

  • Temperature Range: -40°C to +175°C
  • Rated Voltage Range: 16 VDC to 40 VDC
  • Rated Current: Up to 10 ARMS
  • DC Life Test: 2,000 h @ full load, 175 ˚C
  • Capacitance Range: 470µF to 4,700 µF
