Tantalum chip capacitors

14 May 2014 Passive Components

Vishay has extended its Tantamount low-ESR TR3 and standard industrial-grade 293D series of solid tantalum surface-mount chip capacitors with higher ratings up to 75 V in the B, C, D, E, V and W case sizes. Claimed to be the industry’s first 75 V moulded tantalum capacitors, the Vishay Sprague devices are designed to meet the derating requirements of 50% rated voltage in +28 V and +35 V applications.

Providing less expensive options for decoupling in 75 V applications and power supplies at +28 V, and DC/DC conversion at +35 V, these devices are optimised for sensor, industrial control and airborne applications, in addition to telecommunications base stations.

The TR3 series offers a high ripple current carrying capability to 2,50 A. The 293D and TR3 capacitors are offered in six and seven moulded case sizes, respectively, and feature standard RoHS-compliant tin terminations, with Sn/Pb terminations available upon request. Devices in the C, D and E case codes are 100% surge current tested.

The capacitors offer a voltage range from 4 V to 75 V over a temperature range of -55°C to +85°C (to +125°C with voltage derating). They meet the new EIA-717 international qualification specification (in addition to EIA 535BAAC and IEC QC300801/US0001) and are compatible with high-volume pick-and-place equipment to simplify assembly.
