GS4B021541FT

GS4B021541FT Description

The GS4B021541FT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this bussed (BUS) network integrates 7 thin-film resistors with a 1.54KΩ resistance value and a tight ±1% tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount (SMT) assembly. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances compactness with reliability.
