GS4A031780GGT Description

The GS4A031780GGT from TT Electronics/IRC is a high-performance 4-resistor isolated network designed for precision applications. Housed in an 8-pin narrow SOIC ceramic package, it features 178Ω thin-film resistors with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance in critical circuits. With a ±25ppm/°C temperature coefficient, it maintains stability across a 70°C to 125°C derated power range, making it suitable for environments with fluctuating thermal conditions. The 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating cater to moderate-power designs, while its surface-mount gull-wing termination simplifies PCB assembly.
