GS7B021871DT

GS7B021871DT Description

The GS7B021871DT 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) configuration network integrates 13 thin-film resistors, each with a 1.87KΩ resistance and an exceptional ±0.5% absolute tolerance. The device operates over a wide temperature range of 70°C to 125°C (derated) with a ±50ppm/°C temperature coefficient, ensuring stability in fluctuating environments. Its SOIC-C series construction features a rectangular ceramic case, gull-wing termination, and surface-mount compatibility, making it ideal for compact PCB designs. With a maximum voltage rating of 100V and a total power rating of 0.7W (0.05W per resistor), it balances performance and reliability.
