GS4A018872GT

GS4A018872GT Description

The GS4A018872GT 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 88.7KΩ resistance per element with a tight ±2% absolute tolerance and a low ±100ppm/°C temperature coefficient. Its thin-film technology ensures excellent stability and reliability, while the ceramic case style enhances thermal dissipation. Rated for 0.1W (1/10W) per resistor (0.4W total), it operates within a wide temperature range of 70°C to 125°C (derated) and withstands voltages up to 100V. The gull-wing termination and surface-mount design facilitate easy PCB integration.
