GS4B035230FDT Description

The GS4B035230FDT from TT Electronics/IRC is a high-precision 7-resistor thin-film network in an 8-pin SOIC ceramic package, designed for surface-mount applications. It features a 523Ω resistance per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB assembly, while the ceramic case enhances thermal and mechanical durability.

GS4B035230FDT Features

• Precision Network: 7 resistors, each 523Ω ±1%, ideal for matched impedance applications.
• Stable Thin-Film Technology: Delivers ±25ppm/°C TCR for minimal drift under thermal stress.
• Robust Construction: Ceramic SOIC package (4.9mm x 5.99mm x 1.45mm) with ±0.1mm length/height tolerances.
• High Voltage Handling: 100V rating per resistor, exceeding typical network arrays.
• Automation-Friendly: Gull-wing leads and tube packaging streamline pick-and-place processes.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.

GS4B035230FDT Applications

This resistor network excels in precision analog and digital circuits, including:

• Voltage dividers and bus termination in industrial control systems.
• Signal conditioning for sensors and ADCs in medical devices.
• Impedance matching in RF and communication hardware.
• Feedback networks for op-amps in automotive infotainment (non-AECQ200).
• Power supply balancing in test/measurement equipment.

Conclusion of GS4B035230FDT

The GS4B035230FDT combines high accuracy, thermal stability, and compact packaging, making it a superior choice for engineers needing reliable resistor networks in space-constrained, thermally challenging designs. While not PPAP or automotive-qualified, its ceramic construction and thin-film technology offer long-term reliability for industrial and commercial applications. For matched-resistance circuits requiring low TCR and tight tolerances, this model stands out against polymer-based or thicker-film alternatives.
