GS4A021202JT

GS4A021202JT Description

The GS4A021202JT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Packaged in an 8-pin narrow SOIC (SOIC-C series), this 4-resistor isolated network features 12KΩ resistance per element with a ±5% absolute tolerance and a low ±50ppm/°C temperature coefficient. Its thin-film technology ensures superior accuracy and reliability, while the ceramic case style enhances thermal dissipation and mechanical robustness. Rated for 0.1W (1/10W) power dissipation per resistor (0.4W total), it operates across a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. The gull-wing termination and surface-mount design facilitate easy PCB integration, making it ideal for compact, high-density layouts.
