GS7B032872CBT Description

The GS7B032872CBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stability. Housed in a 14-pin narrow SOIC package, this bussed (BUS) network integrates 13 thin-film resistors, each with a 28.7KΩ resistance and an absolute tolerance of ±0.25%. Its ±25ppm/°C temperature coefficient ensures minimal resistance drift across a wide operating range of -70°C to +125°C, making it suitable for precision analog and digital circuits. The SOIC-C series construction offers robust ceramic substrate reliability, with a 0.05W (1/20) power rating per resistor and a total power rating of 0.7W.
