GS4A031271DBT Description

The GS4A031271DBT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for demanding surface-mount applications. Featuring 1.27kΩ thin-film resistors with an absolute tolerance of ±0.5% and a ratio tolerance of ±0.1%, this network delivers exceptional accuracy and stability. Its ±25ppm/°C temperature coefficient ensures minimal resistance drift across a wide operating range of -55°C to +125°C, making it suitable for precision analog and digital circuits. The isolated circuit design (ISOL) allows independent resistor operation, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) ensure reliability in compact designs.
