GS4B021822FT Description

The GS4B021822FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. This 8-pin narrow SOIC (SOIC-C series) device integrates 7 bussed (BUS) thin-film resistors, each with a 18.2KΩ resistance and a tight ±1% absolute tolerance. Operating within a temperature range of 70°C to 125°C, it delivers stable performance with a low ±50ppm/°C temperature coefficient, ensuring minimal resistance drift. The 0.05W (1/20W) power rating per resistor and 0.4W total power rating make it suitable for low-power, high-density designs. Encased in a rectangular ceramic package, it offers excellent thermal stability and durability, with a 100V maximum voltage rating and surface-mount gull-wing termination for reliable PCB integration.
