GS4B027681GDT Description

The GS4B027681GDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed with thin-film technology on a ceramic substrate, it offers a 7.68KΩ resistance per element with a tight ±2% absolute tolerance and ±0.5% ratio tolerance, ensuring precision in matched resistance applications. The device operates over a wide temperature range of 70°C to 125°C (derated) with a ±50ppm/°C temperature coefficient, making it stable under thermal stress. Its SOIC-C series construction provides 0.4W total power dissipation (0.05W per resistor) and a 100V maximum voltage rating, suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case ensures durability.
