Providing design engineers with high stability, high temperature devices for demanding environments, TT electronics IRC has developed a series of high temperature thick film chip resistors. Designated the HTC Series, the chip resistors feature an operating temperature to +200C 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 IRCs 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 1.0ohm to 10Mohm. Maximum voltage ratings for the 1206, 2010 and 2512 chip sizes are 200V, 400V and 500V, respectively. Tolerances are to 0.5%, 1% and 5%, with absolute TCRs of 100ppm/C. Operating temperature ranges from -55C to +200C. IRC will also produce devices outside these specifications to meet customer requirements.
Lead time for HTC Series chip resistors is from 7 to 8 weeks.
