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 Ω to 100 MΩ in 0603, 0805, 1206, and 2010 Case Sizes
MALVERN, Pa. — Dec. 1, 2011 — Vishay Intertechnology, Inc. (VSH: NYSE) 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-hold 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 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 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.
Device Specification Table:
|Case size||Power rating at + 230 °C||Limiting element voltage||Max. overload voltage||Max. resistance|
|0603||12.5 mW||50 V||100 V||25 MΩ|
|0805||20 mW||150 V||300 V||25 MΩ|
|1206||25 mW||200 V||400 V||50 MΩ|
|2010||100 mW||200 V||400 V||100 MΩ|
Samples and production quantities of the CHPHT are available now, with lead times of 13 weeks for larger orders.
