63 V tantalum capacitor

Vishay has extended its Tantamount Hi-Rel COTS T97 series to offer what it claims is the first solid tantalum chip capacitor with a 63 V rating to meet derating requirements in +28 V power supply designs.

With a 63 V rating and capacitance of 22 µF, the device in the ‘F’ case size allows designers to incorporate solid surface-mount tantalum capacitors into their +28 V power supply designs while fully complying with derating requirements.

In addition to the T97 Hi-Rel series, these rings are also available in a commercial version, the 597D series.

Featuring a dual anode construction to ensure low ESR, the T97 series is designed for applications such as those found in the military and aerospace industries, including DC-DC converters and power distribution in weapons and radar systems, avionics and space-based electronics.

The devices offer designers a wide array of rings not found in available MIL specifications, combining the flexibility and convenience of a commercial product with the reliability needed in demanding applications.

These conformal-coated capacitors with wrap-around terminations offer high-reliability screening options, including Weibull grading and surge current testing options in accordance with MIL-PRF-55365 in five case sizes.

The series has a capacitance range of 15 to 1500 µF and a voltage range from 4 to 63. It offers ultra-low ESR values, which range from 0.015 to 0.30Ω at +25°C and 100 kHz.
