GS4B029101JT

GS4B029101JT Description

The GS4B029101JT 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 9.1KΩ resistance per element and a ±5% tolerance, this ceramic-based network ensures reliable performance across a wide temperature range (70°C to 125°C). Its ±50ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for demanding environments. The SOIC-C series construction offers 0.05W (1/20) power rating per resistor (0.4W total), housed in a compact 4.9mm × 5.99mm × 1.45mm footprint with gull-wing termination for easy surface-mount assembly.
