GS4A0257R6DT Description

The GS4A0257R6DT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC ceramic package, it features 57.6Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The thin-film technology delivers superior accuracy and reliability, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for precision circuits. Its gull-wing termination and surface-mount design (4.9mm x 5.99mm x 1.45mm) facilitate compact PCB integration.
