Tantalum surface-mount chip capacitors resist high temperatures

December 05, 2011 // By Christoph Hammerschmidt
Vishay Intertechnology has introduced a series of HI-TMP TANTAMOUNT surface-mount solid tantalum molded chip capacitors with high-temperature capabilities from – 55 °C to + 175 °C with 50 % voltage derating. By operating at much higher temperatures than the industry standard, the AEC-Q200-qualified TH4 capacitors provide designers with a robust and more reliable option for automotive and industrial applications.

Devices in the TH4 series are optimized for a wide variety of high-temperature automotive systems, such as oil quality sensors and transmission, EAGR, throttle, and power train controls. In addition, the devices are ideal for industrial applications related to the control of high-temperature materials; safety-critical industrial tools and products; and sensing tools for oil drilling.

TH4 capacitors are offered in a molded package in three standard EIA-535BAAC case codes: B, C, and D. The devices offer a capacitance range from 10 µF to 47 µF over voltage ratings from 6.3 VDC to 16 VDC, with capacitance tolerances of ±10 % and ±20 %. 100 % surge current tested and compliant to RoHS directive 2002/95/EC, the devices are available with RoHS-compliant tin or gold terminations. Higher voltage and capacitance ratings are included in the TH4 development road map.

Samples and production quantities of the new TH4 series are available now, with lead times of 12 weeks for larger orders.
