GS4A011911FT Description

The GS4A011911FT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 1.91 kΩ resistance and a tight ±1% tolerance. With a ±100 ppm/°C temperature coefficient, it ensures stable performance across a wide operating range of -70°C to +125°C. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) offers a compact footprint, while the gull-wing termination facilitates reliable PCB mounting. Rated for 100V maximum voltage and 0.1W power dissipation per resistor (0.4W total), this network is ideal for precision analog and digital circuits.
