Wraparound Thick Film Chip Resistor survives high temperatures.
December 2, 2011 -
Optimized for multi-chip modules in down-hole drilling instrumentation, CHPHT resistors can operate from -55 to +230°C and be stored from -55 to +245°C. Resistance ranges from 0.1 W to 100 MW; available tolerances include 1%, 2%, and 5%; and power dissipation ranges from 12.5-100 mW at +230°C. Sfernice resistor is available with gold terminations for compatibility with high melting point processes for temperatures to +245°C and with tin/silver terminations for temperatures to +200°C.

Vishay Intertechnology Announces Industry's First Wraparound Thick Film Chip Resistor with Operating Temperature to + 230 °C and Storage Temperature to + 245 °C
Device Offers Wide Resistance Range From 0.1 W to 100 MW in 0603, 0805, 1206, and 2010 Case Sizes
MALVERN, Pa. - Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new high-temperature, surface-mount, wraparound thick film chip resistor. For down-hole drilling applications, the CHPHT is the industry's first such device 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 W to 100 MW; tolerances of 1 %, 2 %, and 5 %; and power dissipation of 12.5 mW to 100 mW at + 230 °C.
The Vishay Sfernice resistor released today 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.
