GS4B037872BAT Description

The GS4B037872BAT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for demanding applications, it features a 78.7KΩ resistance per element with an exceptional ±0.1% absolute tolerance and ±0.05% ratio tolerance, ensuring minimal deviation in critical circuits. The thin-film technology and ceramic case style provide superior stability, with a ±25ppm/°C temperature coefficient for reliable performance across a 70°C to 125°C derated power range. Rated for 100V maximum voltage and 0.4W total power dissipation, this network is ideal for precision analog and digital systems.

GS4B037872BAT Features

• High Precision: ±0.1% tolerance and ±25ppm/°C TCR for stable performance in temperature-varying environments.
