GS7B022872BT

GS7B022872BT Description

The GS7B022872BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. 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 ultra-tight ±0.1% tolerance. The device operates over a wide temperature range (-70°C to +125°C) with a low ±50ppm/°C temperature coefficient, ensuring stability in harsh environments. Its SOIC-C series construction features a rectangular ceramic case, gull-wing terminations, and a surface-mount design, making it suitable for automated assembly. With a 0.7W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances performance and reliability.
