Vishay Intertechnology has introduced a new series of high-energy wet tantalum capacitors which offers the industry’s highest capacitance-voltage product ratings for this device type, across various case sizes.

The new EP1 capacitor series is intended for use in pulse power and energy hold-up applications in military and avionics systems.

Built on Vishay’s proven SuperTan® technology, the EP1 series offers capacitance values up to 13,000μF at 50V in the A case size, some 18% higher than the closest competing device offers.

The capacitor is supplied in an all-tantalum, hermetically-sealed case which offers high reliability in demanding applications. For increased design flexibility, the EP1 is available with radial through-hole or surface-mount terminations, each with a stud-mount option.

Maximum equivalent series resistance values at 1kHz and 25°C range from as low as 0.03Ω to 0.10Ω.

FEATURES

  • Capacitance range: 2,000μF to 30,000μF in the A case size
  • Voltage-rating range: 25V to 125V DC
  • Available in A, B, and C case sizes
  • Capacitance tolerance: ±20% (standard) or ±10%
  • Available with tin/lead or RoHS-compliant 100% tin terminations
  • Operating-temperature range: -55°C to 85°C (125°C with derating)

APPLICATIONS

  • Laser guidance systems
  • Radar equipment
  • Avionics
