GS4A022200GFT Description

The GS4A022200GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. This 4-resistor isolated network features a 220Ω resistance value with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring reliable signal integrity and minimal deviation. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing termination for robust surface-mount assembly. The thin-film technology delivers excellent stability, with a low ±50ppm/°C temperature coefficient, and operates across a wide temperature range of -70°C to +125°C. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it is ideal for isolation and signal conditioning in harsh environments.
