GS4A021782FT

GS4A021782FT Description

The GS4A021782FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 17.8KΩ resistance and a tight ±1% tolerance. The network operates over a wide temperature range of 70°C to 125°C with a derated power capability, ensuring reliability in demanding environments. Its ±50ppm/°C temperature coefficient enhances stability, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for low-power circuits. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations ensures easy surface-mount integration.
