GS4B029091JGT Description

The GS4B029091JGT 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 9.09KΩ resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±2%. The device utilizes thin-film technology on a ceramic substrate, ensuring stable performance across a wide temperature range (70°C to 125°C). With a ±50ppm/°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.

GS4B029091JGT Features

• Bussed Network Topology: Simplifies circuit design by connecting multiple resistors to a common node.
• High Precision: ±5% absolute tolerance and ±2% ratio tolerance ensure consistent performance in matched circuits.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal and long-term stability.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Surface-Mount Ready: Gull-wing terminals with 1.27mm pitch enable easy PCB integration.
• Low TCR: ±50ppm/°C minimizes resistance drift in varying environments.
• Compact Form Factor: SOIC package (4.9mm length) saves board space without sacrificing performance.
