GS8B031581DCT

GS8B031581DCT Description

The GS8B031581DCT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 16-pin narrow SOIC package, this bussed (BUS) configuration integrates 15 thin-film resistors, each with a 1.58KΩ resistance and an exceptional ±0.5% absolute tolerance (±0.25% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures stability across a wide operating range (70°C to 125°C), making it suitable for environments with thermal fluctuations. The SOIC-C series construction offers robust ceramic substrate reliability, while the gull-wing termination facilitates easy surface-mount (SMD) assembly. With a 0.05W (1/20) power rating per resistor and 100V maximum voltage rating, it balances compactness with performance.
