GS4B031101JDT Description

The GS4B031101JDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for precision applications, it features a 1.1KΩ resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±0.5%. The device utilizes thin-film technology on a ceramic substrate, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability under thermal stress. The SOIC-C series construction offers a compact footprint (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations for reliable surface-mount assembly. Rated for 100V maximum voltage and 0.4W total power dissipation, it is ideal for space-constrained, high-reliability designs.
