GS4B033012DT Description

The GS4B033012DT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. This ceramic-based thin-film resistor network offers a 30.1KΩ resistance per element with an ultra-tight ±0.5% absolute tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its SOIC-C series construction provides robust performance in compact designs, with a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating. The gull-wing termination and 1.27mm pitch facilitate reliable PCB mounting, while the ceramic case enhances thermal and mechanical durability.
