GS4B0178R7GGT Description

The GS4B0178R7GGT 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 78.7Ω resistance value with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance across all resistors. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. The thin-film technology provides excellent stability, with a ±100ppm/°C temperature coefficient and a 0.05W (1/20) power rating per resistor, totaling 0.4W for the entire network. Rated for 100V maximum voltage and 125°C maximum operating temperature, it is ideal for environments requiring robust thermal and electrical performance.
