New Yorker Electronics has announced the release of Vishay’s new series of wet tantalum capacitors with hermetic glass-to-metal seals. For avionics and aerospace applications, the STH electrolytic capacitors from New Yorker provide all the advantages of Vishay’s SuperTan® extended series devices, while offering a higher reliability design for improved military H-level shock (500 g) and vibration  capabilities (sine: 80g; random: 54 g) and increased thermal shock up to 300 cycles.

By providing military H-level performance in a SuperTan series, the devices released today offer a lower-cost alternative to Hi-Rel wet tantalum capacitors, while ensuring the high reliability required by more aggressive mission profiles. The STH series is optimized for energy storage in power supplies, actuators, transponders, and radio, radar, and missile systems, in addition to oil drilling and underwater equipment.

The devices feature high capacitances from 470 µF to 1500 µF in the D case code, and capacitance tolerances of ± 20 % standard at 120 Hz and + 25 °C, with tolerances of ± 10 % available. The STH series operates over a temperature range of - 55 °C to + 85 °C, to + 125 °C with voltage derating, and provides low ESR down to 0.50 ? at 120 Hz and + 25 °C. The capacitors feature standard tin / lead (Pb) terminations, with RoHS-compliant 100 % tin terminations available.

Features & Benefits:

  • Enhanced performance, high reliability design
  • Terminations: axial, standard tin / lead (SnPb), 100% tin available
  • Model STH tantalum-case electrolytic capacitors provide all the advantages of Vishay’s SuperTan® extended series devices, while offering improved vibration capability


  • Military
  • Avionics

Samples and production quantities of the new STH wet tantalum capacitors are available now, with lead times of 16 to 20 weeks for larger orders. Samples and production quantities of the new sensors are available now from New Yorker Electronics, with lead times of 16 to 20 weeks. New Yorker Electronics supplies Vishay discrete semiconductors (diodes, MOSFETs and infrared optoelectronics) and passive electronic components (resistors, inductors and capacitors).
