GS4A031870JCT Description

The GS4A031870JCT 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 187Ω and a ±5% absolute tolerance. The device operates within 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 ±25ppm/°C temperature coefficient and ±0.25% ratio tolerance make it ideal for circuits requiring stable performance under thermal stress. The SOIC-C series construction offers 0.1W power rating per resistor (0.4W total), with a 100V maximum voltage rating, and is surface-mountable with gull-wing terminations for easy PCB integration.
