GS4B031802GFT Description

The GS4B031802GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 7-resistor bussed network features an 18KΩ resistance value with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance 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 reliable surface-mount assembly. The thin-film technology delivers excellent stability, with a low ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. Rated for 100V maximum voltage and 0.4W total power dissipation, it operates reliably across a -55°C to +125°C range, with derated power up to 125°C.
