GS4A0251R1JCT Description

The GS4A0251R1JCT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 51.1Ω and a tolerance of ±5%. The device operates over a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in demanding environments. Its ±50ppm/°C temperature coefficient and ±0.25% ratio tolerance make it ideal for applications requiring stable and accurate resistance matching. The SOIC-C series construction provides excellent thermal and mechanical stability, while the gull-wing termination facilitates easy surface mounting.
