GS4B032201CAT Description

The GS4B032201CAT from TT Electronics/IRC is a high-precision 7-resistor bussed network designed for demanding electronic applications. Encased in a ceramic SOIC package, it features 8-pin narrow SOIC (SOIC-C Series) construction with gull-wing termination for reliable surface-mount assembly. This thin-film resistor network delivers 2.2KΩ resistance per element with an exceptional ±0.25% absolute tolerance and ±0.05% ratio tolerance, ensuring minimal deviation in matched circuits. Its ±25ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for stable performance across industrial environments. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its versatility.
