GS4A0227R4JGT Description

The GS4A0227R4JGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 27.4Ω and a ±5% absolute tolerance. The device operates within a wide temperature range of -70°C to +125°C, making it suitable for industrial and automotive-adjacent applications. With a ±50ppm/°C temperature coefficient and a 0.1W power rating per resistor, it ensures stable performance under varying thermal conditions. The SOIC-C series construction provides excellent durability, while the gull-wing termination facilitates reliable surface-mount assembly.
