GS7B032872FFT

GS7B032872FFT Description

The GS7B032872FFT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Packaged in a 14-pin narrow SOIC (SOIC-C series), this bussed network integrates 13 resistors with a 28.7KΩ resistance value and a tight ±1% absolute tolerance. Its thin-film technology ensures excellent stability, with a low ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating thermal conditions. The device operates over a wide temperature range of -70°C to +125°C, derated for power at elevated temperatures. With a maximum voltage rating of 100V and a power rating of 0.7W (0.05W per resistor), it balances performance and reliability in compact designs.
