GS4A021051DBT Description

The GS4A021051DBT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding applications requiring tight tolerance and stability. Housed in an 8-pin narrow SOIC ceramic package, it features 1.05 kΩ thin-film resistors with an absolute tolerance of ±0.5% and a ratio tolerance of ±0.1%, ensuring exceptional accuracy. The device operates over a wide temperature range of -70°C to +125°C with a low ±50 ppm/°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 compact designs. The gull-wing termination and surface-mount compatibility (SOIC package) facilitate easy integration into modern PCB layouts.
