GS8B031872DAT Description

The GS8B031872DAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying thermal conditions. Housed in a 16-pin narrow SOIC package, this bussed network integrates 15 thin-film resistors with a 0.5% absolute tolerance and an ultra-tight ±0.05% ratio tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a resistance value of 18.7KΩ and a ±25ppm/°C temperature coefficient, it delivers reliable operation across a -70°C to +125°C derated power range, making it suitable for industrial and instrumentation environments. The SOIC-C series construction features a rectangular ceramic substrate, gull-wing terminations, and a 100V maximum voltage rating, combining durability with ease of surface-mount assembly.
