Resistors and networks handle the heat

High-temperature resistive products are constructed using IRC's patented TaNFilm self passivating resistive technology.

IRC Advanced Film Division offers a comprehensive range of high-temperature resistive products, including the PFC-HT Series chip resistor, PFC-HT Divider Series voltage divider, 1900 Series DIP resistor network and 4700 Series SIP resistor network.

The devices are constructed using IRC's patented TaNFilm self passivating resistive technology.

"We offer a full complement of high temperature packages, from discretes to high-pin-count networks", said Jerry Seams, Applications Engineering Manager for IRC Advanced Film Division.

"By utilising our TaNFilm technology, we are able to provide customers with a range of resistive products with the stability and reliability necessary for high temperature requirements - up to 200C - including automotive underhood and aerospace applications".

Additional applications for the high temperature products 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 10ohm to 85Kohm, 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 to +200C.

Resistance range for the 1206 PFC-HT Divider Series is 100ohm to 25kohm 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 to +200C.

The high temperature chip resistor and voltage divider feature wraparound nonleaching terminations, with either gold-plated or 100% tin (Pb-free) versions specifically designed to enable the devices to operate at elevated temperatures.

The 1900 Series DIP resistor network features a resistance range from 50ohm to 100kohm, standard tolerances down to +/-0.1%, and available TCR down to +/-10ppm/C.

Operating temperature ranges from -55 to +150C.

The 4700 Series precision SIP network has a resistance range of 20ohm to 400kohm, standard tolerances down to +/-0.05%, and available TCRs to +/-50, +/-100 and +/-300ppm/C.

Voltage rating is 100V and power rating ranges from 0.36 to 1.08W, depending on pin count.

Operating temperature ranges from -55 to +125C.

IRC will also produce devices outside these specifications to meet customer requirements.

Both the 1900 Series and 4700 Series devices are qualified to MIL-PRF-83401, and the PFC-HT and PFC-HT Divider products are qualified to MIL-PRF-55342.
