GS4B034752GFT Description

The GS4B034752GFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 47.5KΩ resistance value, ±2% absolute tolerance, and ±25ppm/°C temperature coefficient, this ceramic-based network ensures reliable performance across a 70°C to 125°C derated power range and up to 125°C maximum operating temperature. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. The SOIC-C series features a compact 4.9mm × 5.99mm × 1.45mm footprint with gull-wing termination for secure surface-mount assembly.
