GS4A031403CT

GS4A031403CT Description

The GS4A031403CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a 140 kΩ resistance and an ultra-tight ±0.25% tolerance. With a ±25 ppm/°C temperature coefficient, it ensures stable performance across a wide temperature range of 70°C to 125°C. The SOIC-C series construction offers 0.1W (1/10W) power rating per resistor (0.4W total), a 100V maximum voltage rating, and gull-wing termination for reliable surface-mount assembly. Its ceramic case provides excellent thermal and mechanical stability, making it ideal for precision circuits.
