GS4B039311FT Description

The GS4B039311FT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications. Built with ceramic substrate and thin-film technology, it offers a 9.31KΩ resistance per element with a tight ±1% tolerance and low ±25ppm/°C temperature coefficient, ensuring stability across a 70°C to 125°C derated power range. The SOIC-C series construction provides robust thermal and mechanical performance, with a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ±0.1mm height/length tolerances ensure consistent PCB placement.

GS4B039311FT Features

• Precision Network: 7 bussed resistors with 9.31KΩ ±1% absolute tolerance.
• Stable Performance: ±25ppm/°C TCR for minimal drift in varying temperatures.
• Robust Construction: Ceramic case and thin-film technology enhance durability and heat dissipation.
• Compact & Reliable: 4.9mm x 5.99mm footprint with 1.45mm profile, ideal for space-constrained designs.
• Automation-Friendly: Gull-wing leads and 1.27mm pitch for seamless SMT integration.
• Wide Operating Range: -55°C to +125°C (full power up to 70°C, derated to 125°C).

GS4B039311FT Applications

This resistor network excels in precision analog circuits, voltage dividers, and signal conditioning where stability and compactness are critical. Key use cases include:

• Industrial Controls: Sensor interfaces and feedback loops requiring low TCR.
• Medical Devices: High-reliability instrumentation with strict tolerance requirements.
• Automotive Electronics (non-AECQ): Non-safety-critical systems like infotainment or lighting.
• Test & Measurement Equipment: Calibration circuits and reference networks.

Conclusion of GS4B039311FT

The GS4B039311FT stands out for its ceramic-based reliability, tight tolerance, and low thermal drift, making it a superior choice for precision DC/analog applications. While not PPAP or automotive-grade, its industrial-grade robustness and compact SOIC package cater to demanding environments. Engineers will value its repeatable performance and ease of integration, particularly in high-density PCBs or temperature-variable systems. For designs prioritizing accuracy over wide compliance (e.g., non-EU RoHS), this network delivers exceptional value.
