GS7B021782FT

GS7B021782FT Description

The GS7B021782FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. Packaged in a 14-pin narrow SOIC (SOIC-C Series), this bussed network integrates 13 thin-film resistors, each with a 17.8KΩ resistance and a tight ±1% tolerance. The device operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±50ppm/°C, ensuring stable performance under thermal stress. Its 0.05W (1/20) power rating per resistor and 0.7W total power rating make it suitable for low-power, high-density designs. The 100V maximum voltage rating and surface-mount gull-wing termination further enhance its reliability in compact PCB layouts.
