GS4B034420CT Description

The GS4B034420CT from TT Electronics/IRC is a high-precision 7-resistor bussed network in a narrow SOIC (SOIC-C) package, designed for demanding surface-mount applications. This ceramic-based thin-film resistor array offers a 442Ω resistance per element with an exceptional ±0.25% absolute tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its 8-pin gull-wing termination and 1.27mm pitch facilitate reliable PCB integration, while the 0.05W (1/20) power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The EU RoHS non-compliant construction is housed in a 4.9mm x 5.99mm x 1.45mm ceramic case, providing robust thermal and mechanical performance.
