GS4A021803CBT Description

The GS4A021803CBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a 180 kΩ resistance and an absolute tolerance of ±0.25%. The device operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±50 ppm/°C, ensuring stable performance under thermal stress. Its 0.1W (1/10) power rating per resistor and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The SOIC-C series construction provides robust mechanical stability, while the gull-wing termination ensures reliable surface-mount assembly.
