GS7A0178R7GGT Description

The GS7A0178R7GGT from TT Electronics/IRC is a high-performance 7-resistor isolated network designed for precision applications. Housed in a 14-pin narrow SOIC ceramic package, it features 78.7Ω resistance per element with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance in matched-resistor circuits. Its thin-film technology delivers excellent stability with a ±100ppm/°C temperature coefficient, making it suitable for environments with fluctuating thermal conditions. Rated for 0.1W power dissipation per resistor (0.7W total) and 100V maximum voltage, it operates reliably across a 70°C to 125°C derated power range, with a 125°C maximum operating temperature. The gull-wing termination and surface-mount design facilitate easy PCB integration.
