GS4B033921GBT Description

The GS4B033921GBT from TT Electronics/IRC is a high-precision 7-resistor network designed for surface-mount applications in demanding electronic circuits. Encased in a ceramic SOIC-8 package, this thin-film resistor array offers a 3.92KΩ resistance per element with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in precision analog and digital systems. The gull-wing termination and 1.27mm pitch facilitate easy PCB integration, while its ceramic substrate enhances thermal stability and durability.
