GS4B031782FDT Description

The GS4B031782FDT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC package, designed for surface-mount applications. With a 17.8KΩ resistance per resistor, a tight 1% tolerance, and a low ±25ppm/°C temperature coefficient, this component ensures stable performance in demanding environments. The ceramic case style and gull-wing termination provide robust mechanical and thermal stability, while the 0.4W total power rating (0.05W per resistor) supports efficient power dissipation. Rated for 100V maximum voltage and 125°C maximum operating temperature, it is suitable for industrial and commercial circuits requiring precision and reliability.

GS4B031782FDT Features

• 7-resistor network with BUS circuit designator, ideal for signal distribution.
• Thin film technology ensures low noise and high accuracy (±1% tolerance).
• Ceramic SOIC package (4.9mm × 5.99mm × 1.45mm) with ±0.1mm length/height tolerances for consistent PCB assembly.
• Gull-wing SMD termination (1.27mm pitch) for secure soldering.
• Wide temperature range (70°C to 125°C derated) and ±25ppm/°C TCR for thermal stability.
• Non-automotive (PPAP No) but suited for industrial controls, test equipment, and communication systems.

GS4B031782FDT Applications

This resistor network excels in:

• Voltage divider circuits and bus termination in digital systems.
• Precision analog signal conditioning (e.g., sensor interfaces, ADCs).
• Embedded systems requiring compact, multi-resistor solutions.
• Medical devices and test instrumentation where low TCR and high stability are critical.
• Power management modules due to its 100V rating and ceramic isolation.

Conclusion of GS4B031782FDT

The GS4B031782FDT combines high precision, robust packaging, and thermal resilience, making it a superior choice for dense PCB designs needing reliable resistor networks. Its thin film construction, tight tolerances, and gull-wing SMD compatibility offer advantages over thicker-film or less stable alternatives. While not RoHS-compliant, it remains ideal for industrial and precision electronics where performance outweighs regulatory constraints.
