GS4B031372GAT Description

The GS4B031372GAT from TT Electronics/IRC is a high-performance 7-resistor thin-film network designed for precision applications. Encased in a ceramic SOIC-8 package, it offers a 13.7KΩ resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. 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 surface-mount design facilitate easy PCB integration, while the ceramic substrate enhances thermal and mechanical reliability.

GS4B031372GAT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±25ppm/°C) for sensitive analog/digital circuits.
• Robust Ceramic Package: Superior heat dissipation and durability compared to polymer-based arrays.
• BUS Circuit Design: Optimized for bus termination, voltage division, and pull-up/down applications.
• Compact & Reliable: 4.9mm × 5.99mm × 1.45mm dimensions with tight tolerances (±0.1mm height/length).
• Automotive-Grade Alternatives: While not PPAP/automotive-certified, its 125°C max temperature suits industrial and telecom environments.

GS4B031372GAT Applications

• Signal Conditioning: Ideal for ADC/DAC reference networks and sensor interfaces.
• Bus Termination: Reduces reflection in high-speed data lines (e.g., DDR, PCIe).
• Power Management: Used in voltage dividers for feedback loops in DC-DC converters.
• Industrial Controls: Stable performance in PLCs, motor drives, and instrumentation.
• Telecom Hardware: Reliable in RF modules and base station circuitry.

Conclusion of GS4B031372GAT

The GS4B031372GAT excels in precision and durability, leveraging thin-film technology and ceramic construction for critical applications.
