IRC Develops High Temperature Thick Film Chip Resistors Capable Of Operation To 200°C

August 02, 2009 by Jeff Shepard

IRC Inc. has developed a series of high temperature thick film chip resistors. Designated the HTC Series, the chip resistors feature an operating temperature to +200°C and are available in standard chip sizes including 1206, 2010 and 2512 packages.

"These resistors exhibit excellent stability at extremely high temperatures, as well as superior power handling capabilities and an extended resistance range and working voltage ratings," said Gary Bleasdell, Director of IRC’s Thick Film Business Unit. "These electrical characteristics make the HTC Series resistors ideal for a variety of harsh environments including automotive underhood, aerospace, down-hole instrumentation, oil and gas equipment, motor controls, power supply and circuit-protection applications."

The thick film chip resistors feature Pb-free wrap-around terminations with a leach-resistant nickel barrier. The resistors meet MIL-STD-202 specifications for load life, moisture resistance and thermal shock.

The HTC Series resistors feature a resistance range from 1.0Ω to 10mΩ. Maximum voltage ratings for the 1206, 2010 and 2512 chip sizes are 200, 400 and 500V, respectively. Tolerances are to +/-0.5%, +/-1% and +/-5%, with absolute TCRs of +/-100ppm/°C. Operating temperature ranges from -55 to +200°C. IRC will also produce devices outside these specifications to meet customer requirements.

Typical pricing for the HTC Series chip resistors ranges from $0.37 to $0.42 each in minimum order quantities of 5,000 pieces. Lead time is from 7 to 8 weeks.
