GS4B034640JFT Description

The GS4B034640JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. This 7-resistor bussed network features a 464Ω resistance value with an absolute tolerance of ±5% and a ratio tolerance of ±1%, ensuring consistent performance across all elements. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint with dimensions of 4.9mm (L) × 5.99mm (D) × 1.45mm (H) and a gull-wing termination for reliable surface-mount assembly. The thin-film technology delivers a low temperature coefficient of ±25ppm/°C, stable across an operating range of -70°C to +125°C. With a maximum voltage rating of 100V and a total power rating of 0.4W (0.05W per resistor), this network is ideal for high-density PCB designs requiring robust thermal and electrical performance.
