GS4B011821CT Description

The GS4B011821CT 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 bussed (BUS) configuration device integrates 7 thin-film resistors, each with a 1.82KΩ resistance and an exceptional ±0.25% absolute tolerance. Its ±100ppm/°C temperature coefficient ensures stable performance across a wide operating range of 70°C to 125°C, making it suitable for precision circuits. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount (SMD) assembly. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances compactness with reliability.
