Corpus Christi, Tex. TT electronics IRC Advanced Film Division offers a wide range of high-temperature resistive products that are rated up to 200 degrees C. Targeted at automotive and aerospace applications, these product lines include the PFC-HT series chip resistor, PFC-HT Divider series voltage divider, 1900 series DIP resistor network and 4700 series SIP resistor network.
The high-temperature devices are constructed using IRC's TaNFilm self passivating resistive technology. Other applications for these devices include satellites, down-hole instrumentation, and oil and gas well-logging equipment.
The PFC-HT series chip resistors are available in 0603, 0805 and 1206 chip sizes, and feature a resistance range from 10 ohms (Ω) to 85 KΩ, with tolerances to ±1% and absolute temperature coefficient of resistance (TCR) values down to ±25 ppm/°C. Voltage and power ratings are 33.3 V/62.5 mW, 50 V/100 mW and 100 V/125 mW, respectively, with an operating temperature range of -55°C to +200°C.
Resistance range for the 1206 PFC-HT Divider series is 100Ω to 25 KΩ per resistor, with a power rating of 100 mW per resistor, absolute TCR to ±25 ppm/°C and a maximum voltage rating of 100 V. The operating temperature range is -65°C to +200°C.
The 1900 series DIP resistor network features a resistance range from 50Ω to 100 KΩ, standard tolerances down to ±0.1%, and available TCR down to ±10 ppm/°C. Operating temperature ranges from -55°C to +150°C.
The 4700 series precision SIP network provides a resistance range of 20Ω to 400 KΩ, standard tolerances down to ±0.05%, and available TCRs to ±50 ppm/°C, ±100 ppm/°C and ±300 ppm/°C. Voltage rating is 100 V and power rating ranges from 0.36 W to 1.08 W, depending on pin count. The operating temperature range is -55°C to +125°C.
Both the 1900 series and 4700 series devices are qualified to MIL-PRF-83401, while the PFC-HT and PFC-HT divider products are qualified to MIL-PRF-55342. Custom specifications are available.
