Vishay Intertechnology, Inc. announced that it 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. The industry's first 75 V molded 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, the devices released today are optimized 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 molded 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. Part of Vishay's TANTAMOUNT tantalum capacitor family, the devices released today 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. The capacitors meet the new EIA-717 international qualification specification (in addition to EIA 535BAAC and IEC QC300801/US0001), offer a Moisture Sensitivity Level of 1, and are compatible with high-volume pick-and-place equipment to simplify assembly.
Samples and production quantities of the new 75 V solid tantalum chip capacitors are available now, with lead times of seven to nine weeks for larger orders. Pricing for U.S. delivery starts at $1.10 per piece.
