GS4B014752BT Description

The GS4B014752BT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for demanding applications, it features a 47.5KΩ resistance per element with an ultra-tight ±0.1% tolerance and a ±100ppm/°C temperature coefficient. The network employs thin-film technology on a ceramic substrate, ensuring stability and reliability across a -70°C to +125°C operating range. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it is suited for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the SOIC package offers compact integration.
