GS4A012211FT Description

The GS4A012211FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 2.21 kΩ resistance and a tight ±1% tolerance. Its SOIC package (4.9 mm × 5.99 mm × 1.45 mm) ensures compact surface-mount integration, while the ceramic case style enhances durability and thermal dissipation. Rated for 0.1 W per resistor (0.4 W total), it operates across a wide temperature range (-70°C to +125°C) with a low ±100 ppm/°C temperature coefficient, ensuring minimal drift. The gull-wing termination and 1.27 mm pitch facilitate reliable PCB assembly.
