GS4A0166R5GT

GS4A0166R5GT Description

The GS4A0166R5GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network offers a 66.5Ω resistance per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient. The thin-film technology ensures excellent stability and reliability, while the ceramic case provides superior thermal and mechanical durability. Rated for 0.1W per resistor (0.4W total), it operates across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The gull-wing termination and surface-mount design facilitate easy PCB integration.
