IRC High Temperature Resistive Devices

IRC's Family of high temperature resistive devices are rated up to 200° and are ideal for automotive and aerospace applications. The discrete, network resistors are available in high temperature packages and are ideal for operation in harsh environments. 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. The high temperature chip resistor and voltage divider feature wraparound non-leaching terminations, with either gold-plated or 100% tin (Pb-free) versions specifically designed to enable the devices to operate at elevated temperatures.

The PFC-HT Series chip resistors are available in 0603, 0805 and 1206 chip sizes, and feature a resistance range from 10Ω to 85KΩ, with tolerances to ±1% and absolute TCRs down to ±25ppm/°C. Voltage and power ratings are 33.3V/62.5mW, 50V/100mW and 100V/125mW, respectively, with an operating temperature range of -55°C to +200°C. Resistance range for the 1206 PFC-HT Divider Series is 100Ω to 25KΩ per resistor, with a power rating of 100mW per resistor, absolute TCR to ±25ppm/°C and a maximum voltage rating of 100V. Operating temperature ranges from -65˚C to +200˚C. The 1900 Series DIP resistor network features a resistance range from 50Ω to 100KΩ, standard tolerances down to ±0.1%, and available TCR down to ±10ppm/°C. Operating temperature ranges from -55˚C to +150˚C. The 4700 Series precision SIP network has a resistance range of 20Ω to 400KΩ, standard tolerances down to ±0.05%, and available TCRs to ±50ppm/°C, ±100ppm/°C and ±300ppm/°C. Voltage rating is 100V and power rating ranges from 0.36W to 1.08W, depending on pin count. Operating temperature ranges from -55°C to +125°C.
