GS4B012872BT Description

The GS4B012872BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stable performance. This 7-resistor bussed network features a 28.7KΩ resistance per element with an absolute tolerance of ±0.1%, ensuring exceptional accuracy. 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 ±100ppm/°C temperature coefficient provide stable operation across a wide temperature range (70°C to 125°C). Rated for 100V maximum voltage and 0.4W total power dissipation, it is ideal for precision analog and digital circuits.
