GS4A031072FBT Description

The GS4A031072FBT from TT Electronics/IRC is a high-precision 4-resistor network designed for demanding isolation and signal conditioning applications. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features isolated thin-film resistors with a 10.7KΩ resistance value, ±1% absolute tolerance, and ±0.1% ratio tolerance, ensuring exceptional accuracy in matched resistance pairs. The device operates over a wide temperature range of -70°C to +125°C with a ±25ppm/°C temperature coefficient, making it suitable for environments with thermal fluctuations. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) provide reliable performance in low-power circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration.
