GS4B035112FDT Description

The GS4B035112FDT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it offers a 51.1KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this component is ideal for precision analog and digital circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB assembly, while the ceramic substrate enhances thermal and mechanical durability.

GS4B035112FDT Features

• Circuit Designator: BUS configuration for streamlined integration.
• Thin Film Technology: Delivers superior accuracy and stability vs. thick film alternatives.
• Robust Construction: Ceramic case ensures high thermal conductivity and resistance to environmental stress.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm footprint suits dense PCB layouts.
• Automotive-Grade Alternatives Available: While this variant is non-automotive (PPAP: No), IRC offers similar compliant models.
• Non-RoHS: Note: EU RoHS non-compliant; alternatives may be needed for restricted applications.

GS4B035112FDT Applications

This resistor network excels in:

• Voltage Division & Pull-Up/Down Circuits: Precision resistance matching critical for ADC/DAC interfaces.
• Bus Termination: Low TCR minimizes signal drift in high-speed data lines (e.g., SPI, I²C).
• Industrial Controls: Stable performance in harsh environments (e.g., motor drives, PLCs).
• Test & Measurement Equipment: Thin film accuracy ensures repeatable calibration.
• Aerospace & Defense: Ceramic packaging suits high-reliability systems (though compliance checks are advised).

Conclusion of GS4B035112FDT

The GS4B035112FDT combines precision, durability, and compact design, making it a standout choice for high-performance electronics. Its ceramic SOIC package and thin film technology provide advantages over polymer-based networks, particularly in thermal management and long-term stability. While not RoHS-compliant, it remains a robust solution for industrial, communications, and instrumentation designs requiring tight-tolerance resistor arrays. Engineers should evaluate alternative part numbers for automotive or RoHS-mandated projects.
