GS8B017872DCT

GS8B017872DCT Description

The GS8B017872DCT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance across a wide temperature range. Housed in a 16-pin narrow SOIC package, this bussed (BUS) resistor array integrates 15 thin-film resistors, each with a 78.7KΩ resistance and a tight ±0.5% absolute tolerance (±0.25% ratio tolerance). The device operates over a temperature range of 70°C to 125°C with a ±100ppm/°C temperature coefficient, ensuring minimal drift in harsh environments. With a 0.05W (1/20W) power rating per resistor and a 100V maximum voltage rating, it is engineered for reliability in precision circuits. The SOIC-C series construction features gull-wing termination for robust surface-mount (SMD) assembly, while the ceramic case enhances thermal and mechanical stability.
