200°C wet tantalum capacitors are tough for the hard life

Vishay T24 SMD hi temp wet tantalum capacitors

The surface-mount T24 series consists of two devices, both 9 x 7.1 x 7.4mm (case code ‘C’).

  • 33μF – 45V at 200°C  (75V -55 to 85°C)  2.5Ωmax ESR (+25°C 120Hz)
  • 10μF – 75V at 200°C  (125V -55 to 85°C) 5.5Ωmax ESR (+25°C 120Hz)

Capacitance tolerance is ± 10% or ± 20% (standard).

In both cases, maximum leakage is 1μA at 25°C (5μA at 85/125°C).

Thermal shock tolerance is 300 cycles (MIL-STD-202, method 107, condition A – tested with MIL-PRF-39006).

“Featuring a glass-to-tantalum hermetic seal and a life rated to 2,000 hours [+200°C], it offers a smaller size and footprint than equivalent through-hole and over-moulded high temperature devices,” according to New Yorker Electronics, which is stocking the parts. “Vishay’s wet tantalum capacitors have been optimised for timing, filtering, energy hold-up and pulse power applications.”
