GS4B034872GGT Description

The GS4B034872GGT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 48.7KΩ resistance per element with a tight ±2% absolute tolerance and ±2% ratio tolerance, this ceramic-based thin-film network ensures stable performance across a -70°C to +125°C temperature range. Its ±25ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The SOIC-C series construction offers robust mechanical stability, with a compact 4.9mm × 5.99mm × 1.45mm footprint and gull-wing terminations for reliable PCB mounting.
