GS4A031781DAT Description

The GS4A031781DAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying conditions. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features a 1.78KΩ resistance value with an absolute tolerance of ±0.5% and an exceptional ratio tolerance of ±0.05%. Its thin-film technology ensures low noise and high reliability, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across a wide operating range of -70°C to +125°C. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, this component is engineered for precision analog and digital circuits.
