GS4B031211FT Description

The GS4B031211FT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 7-resistor bussed network features a 1.21KΩ resistance per element with an absolute tolerance of ±1%, ensuring consistent performance in precision circuits. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. The thin-film technology and ±25ppm/°C temperature coefficient provide excellent stability across a wide operating range (-70°C to +125°C), making it suitable for environments with thermal fluctuations. Rated for 100V maximum voltage and 0.4W total power dissipation, this network is ideal for analog and digital signal conditioning.
