GS4B027320BT Description

The GS4B027320BT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for surface-mount applications, it features a 732Ω resistance per element with an ultra-tight ±0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The thin-film technology delivers superior accuracy and reliability, while the 0.05W (1/20W) power rating per resistor and 0.4W total power rating make it suitable for low-power circuits. Its 100V maximum voltage rating and gull-wing termination ensure robust performance in compact designs.
