GS4A034702GBT

GS4A034702GBT Description

The GS4A034702GBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 47KΩ resistance and a tight ±2% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures stability across a wide operating range of 70°C to 125°C, with a derated power rating of 0.1W per resistor (0.4W total). The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, making it ideal for space-constrained designs. With a 100V maximum voltage rating and gull-wing termination, it supports robust surface-mount assembly.
