GS4B033902CT Description

The GS4B033902CT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for demanding applications, it features a 39 kΩ resistance value with an ultra-tight ±0.25% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The thin-film technology delivers superior accuracy and reliability, while the 0.05W (1/20) power rating per resistor and 0.4W total power rating make it suitable for compact, power-sensitive designs. Its 100V maximum voltage rating and gull-wing termination facilitate robust surface-mount (SMD) integration in space-constrained PCBs.

GS4B033902CT Features

• Ceramic SOIC Package: Enhances thermal performance and mechanical durability.
