GS4B024872BT Description

The GS4B024872BT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 48.7KΩ resistance per element with an ultra-tight ±0.1% tolerance and a low ±50ppm/°C temperature coefficient, this ceramic-based thin-film network ensures exceptional stability and accuracy. The SOIC-C series construction offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable PCB mounting. Rated for 100V maximum voltage and 0.4W total power dissipation, it operates across a 70°C to 125°C derated range, making it suitable for precision analog and digital circuits.

GS4B024872BT Features
