GS4A021200FCT Description

The GS4A021200FCT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 4-resistor isolated network features a 120Ω resistance value with a tight ±1% absolute tolerance and an exceptional ±0.25% ratio tolerance, ensuring reliable signal integrity in demanding circuits. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for secure surface mounting. The thin-film technology delivers stable performance across a wide temperature range (70°C to 125°C), supported by a low ±50ppm/°C temperature coefficient. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it is ideal for isolation and impedance matching in analog and digital systems.
