GS4B017872CAT Description

The GS4B017872CAT 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 with a 78.7KΩ resistance value and an exceptional ±0.25% absolute tolerance. Its ±100ppm/°C temperature coefficient ensures stability across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The SOIC-C series construction features a rectangular ceramic case, gull-wing termination, and surface-mount compatibility, offering robust mechanical and electrical performance. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances power handling with precision.
