Vishay – TR3 Series: 75V Molded Tantalum Capacitor Offers Low ESR

Vishay’s TANTAMOUNT®TR3 series of solid tantalum surface mount chip capacitors offers higher ratings up to 75V in the A, B, C, D, E, V and W case sizes.

The TR3 series, which is intended for applications requiring low Equivalent Series Resistance (ESR), provides the industry with 75V molded tantalum capacitors.

Providing less expensive options for decoupling in 75V applications, for power supplies at +28V, and for DC/DC conversion at +35V, the TR3 devices are ideal for sensor, industrial control and airborne applications, and are expected to be widely used as well in telecommunications base stations.

The TR3 series offers a high ripple current carrying capability, with the largest devices rated for 2.5A.

The capacitors are offered in seven molded case sizes and feature standard RoHS-compliant tin terminations. Devices in the C, D and E case codes are 100% surge current tested.

The TR3 meets the new EIA-717, EIA 535BAAC and IEC QC300801/US0001 international qualification specifications.
