GS7B025490JCT Description

The GS7B025490JCT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. This 14-pin narrow SOIC (SOIC-C Series) device integrates 13 bussed resistors with a 549Ω resistance value, offering a ±5% absolute tolerance and an exceptional ±0.25% ratio tolerance. Built with thin-film technology, it ensures stable performance across a wide temperature range (70°C to 125°C) and features a ±50ppm/°C temperature coefficient. The 0.05W (1/20) power rating per resistor and 0.7W total power rating make it suitable for low-power, high-density designs. Its 100V maximum voltage rating and surface-mount gull-wing termination enhance reliability in compact PCB layouts.
