Vishay Launches New Low-ESR Surface-Mount Hi-Rel COTS TANTAMOUNT Solid Tantalum Chip Capacitors
Vishay Intertechnology, Inc. today introduced a new surface-mount Hi-Rel COTS series of solid tantalum chip capacitors that combines Weibull grading and surge-current test options per MIL PRF 55365, a low-ESR option, and built-in fuses for high reliability and protection against short circuits in critical applications.
T86 series devices feature an internal fusing mechanism that activates at + 25 °C for 0.1 s with a 5 A minimum applied current. In the event of a failure due to excessive current flow, this fusing prevents damage to circuit components in high-reliability avionics and military applications, such as radar, missiles, and other weapons systems.

The option of low ESR values, which extend down to 0.25 Ω at + 25 °C and 100 kHz, allows for more efficient filtering in applications requiring maximum reliability, such as safety-critical industrial applications, medical instrumentation, and diagnostic, high-end computing and data storage. The capacitors' high ripple current handling capability ensures stable output voltages.

The devices released today, part of Vishay's TANTAMOUNT® tantalum capacitor family, are offered in the C, D, E molded case sizes and have a capacitance range of 0.47 μF to 470 μF and voltage range from 4 V to 50 V. Their extended capacitance/voltage values — coupled with reliability, surge current, and ESR options — make the T86 tantalum capacitors a flexible solution for a wide variety of application and performance requirements.

Compatible with high-volume automatic pick-and-place equipment, the T86 series features standard RoHS-compliant tin terminations, with Sn/Pb terminations available. The capacitors operate over a temperature range of – 55 °C to + 125 °C.
