GS4B034991FCT Description

The GS4B034991FCT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. It features a 4.99KΩ resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Encased in a ceramic SOIC-8 package, this network offers a 0.4W total power rating (0.05W per resistor) and a maximum voltage rating of 100V. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB mounting, while the compact dimensions (4.9mm x 5.99mm x 1.45mm) make it suitable for space-constrained designs.

GS4B034991FCT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±25ppm/°C) for stable operation in varying environments.
• Robust Ceramic Construction: Enhances thermal stability and durability compared to polymer-based alternatives.
• Optimized Power Handling: 0.4W total dissipation (0.05W per resistor) supports moderate-power applications.
• Automation-Friendly Packaging: Supplied in tubes for efficient pick-and-place assembly.
• BUS Circuit Designator: Ideal for bus line termination and signal conditioning in digital systems.
• Non-Automotive (PPAP No): Suitable for industrial, telecom, and consumer electronics where PPAP compliance is not required.

GS4B034991FCT Applications

This resistor network excels in:

• Voltage Division & Pull-Up/Down Circuits: Precision resistance matching ensures consistent signal integrity.
• ADC/DAC Interface Networks: Low TCR minimizes drift in analog signal chains.
• Bus Termination (I2C, SPI): Reduces reflections in high-speed digital lines.
• Industrial Control Systems: Ceramic casing withstands harsh operating conditions.
• Medical & Test Equipment: Thin film technology meets stringent accuracy demands.

Conclusion of GS4B034991FCT

The GS4B034991FCT combines precision, compactness, and reliability, making it a standout choice for signal conditioning and termination tasks. Its ceramic SOIC package and thin film resistors offer superior performance over thick-film networks, particularly in temperature-sensitive or high-accuracy applications. While not RoHS-compliant, it remains a cost-effective solution for non-automotive sectors requiring stable, matched resistances. Engineers will appreciate its balance of size, power handling, and electrical consistency in demanding designs.
