Tantalum capacitors beat shock and vibration

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 provide the advantages of Vishay’s SuperTan extended series devices, while offering a higher reliability design for improved military H-level shock (500g) and vibration capabilities (sine: 80g; random: 54g) and increased thermal shock up to 300 cycles.

The company states the devices 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/missile systems, plus oil drilling and underwater equipment.

The devices feature high capacitances from 470μF to 1500μF in D case code and capacitance tolerances of ± 20% standard at 120Hz and +25°C, with tolerances of ± 10% available.

Samples and production quantities are available now, with lead times of 16 to 20-weeks for larger orders.
