GS4B0127R4GGT Description

The GS4B0127R4GGT from TT Electronics/IRC is a high-reliability ceramic resistor network designed for precision applications. This 7-resistor bussed network is housed in an 8-pin narrow SOIC package, offering a compact footprint with 27.4Ω resistance per element and a tight ±2% absolute tolerance. Built using thin-film technology, it ensures stable performance with a ±100ppm/°C temperature coefficient, making it suitable for environments with fluctuating thermal conditions. The SOIC-C series construction provides robust mechanical integrity, while the gull-wing termination facilitates easy surface-mount assembly. With a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C, this component is engineered for demanding circuits requiring consistent resistance values under varying loads.
