GS4A022870CT Description

The GS4A022870CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network offers a 287Ω resistance with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient. Its thin-film technology ensures stable performance across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. The device features gull-wing terminations for reliable surface-mount (SMD) assembly and is packaged in a tube for automated handling. With a power rating of 0.4W (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for precision signal conditioning and isolation circuits.
