GS4A031803CT

GS4A031803CT Description

The GS4A031803CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a 180kΩ resistance and an ultra-tight ±0.25% tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in harsh environments. Its ±25ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision circuits. The SOIC-C series construction offers robust ceramic substrate performance, with a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating.
