Wraparound thick film chip resistors operate from – 55 to +230 °C

December 05, 2011 // Julien Happich

Designed for down-hole drilling applications, Vishay Intertechnology's CHPHT is what the company claims to be the industry's first wraparound thick film chip resistor to offer an operating temperature range from – 55°C to +230 °C and a storage temperature range of – 55°C to + 245°C. Optimized for multi-chip modules (MCM) in down-hole drilling instrumentation, the high-temperature capabilities of the CHPHT resistor allow for the extraction of petroleum at deeper depths.

Offered in 0603, 0805, 1206, and 2010 case sizes (with other sizes available upon request), the resistor offers a wide resistance range from 0.1 Ω to 100 MΩ; tolerances of 1 %, 2 %, and 5 %; and power dissipation of 12.5 to 100mW at + 230°C. The Vishay Sfernice resistor is available with gold terminations for compatibility with high melting point (HMP) processes (< 1 μm thick) for temperatures up to + 245 °C and with tin/silver terminations for operating temperatures up to + 200 °C. The device is compliant to RoHS Directive 2002/95/EC and halogen-free according to the IEC 61249-2-21 definition. Samples and production quantities of the CHPHT are available now, with lead times of 13 weeks for larger orders.
