GS4B026040GT

GS4B026040GT Description

The GS4B026040GT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding environments. Encased in a ceramic SOIC package, this thin-film resistor network offers a 604Ω resistance per element with a tight ±2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -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 compact, surface-mount designs. The 8-pin narrow SOIC (SOIC-C) package features gull-wing leads for robust PCB mounting, while its ceramic construction enhances thermal and mechanical durability.

GS4B026040GT Features
