GS4B031271BT Description

The GS4B031271BT 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 1.27KΩ resistance per element with an ultra-tight ±0.1% tolerance, this ceramic-based thin-film network ensures exceptional stability and accuracy. Its ±25ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments requiring reliable performance under thermal stress. The SOIC-C series construction offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for secure PCB mounting. Rated for 100V maximum voltage and 0.4W total power dissipation, it balances precision with robustness.
