GS4B022801BAT Description

The GS4B022801BAT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding circuit applications. Built with thin-film technology on a ceramic substrate, it delivers exceptional stability with a ±50ppm/°C temperature coefficient and ±0.1% absolute tolerance. The network features a 2.8KΩ resistance value per element, rated for 0.05W (1/20) power dissipation per resistor and 0.4W total power. Its 100V maximum voltage rating and 125°C operating temperature range ensure reliability in harsh environments. The gull-wing termination and surface-mount design facilitate automated assembly, while the SOIC package (4.9mm x 5.99mm x 1.45mm) offers compact integration.

GS4B022801BAT Features

• Precision Performance: Ultra-tight ±0.1% tolerance and ±0.05% ratio tolerance for critical analog/digital signal conditioning.
