GS4B012550BT

GS4B012550BT Description

The GS4B012550BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stable performance. Housed in an 8-pin narrow SOIC package, this bussed (BUS) network integrates 7 thin-film resistors, each with a 255Ω resistance and an exceptional ±0.1% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a ±100ppm/°C temperature coefficient, ensuring minimal resistance drift. Its 0.05W (1/20) power rating per resistor and 0.4W total power rating make it suitable for low-power circuits, while the 100V maximum voltage rating adds versatility. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount (SMD) assembly.
