GS4B034220FCT Description

The GS4B034220FCT from TT Electronics/IRC is a high-performance 7-resistor thin-film network in an 8-pin SOIC package, designed for precision applications. With a 422Ω resistance per element and a tight 1% tolerance, this network ensures reliable signal conditioning and voltage division. Its ±25ppm/°C temperature coefficient and 0.4W total power rating (0.05W per resistor) make it suitable for stable operation across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. The ceramic case and gull-wing termination provide robust mechanical and thermal performance, while the 100V maximum voltage rating ensures durability in demanding circuits. Packaged in a tube, it is optimized for automated SMD assembly.

GS4B034220FCT Features

• Precision Thin Film Technology: Delivers low noise and high stability (±25ppm/°C).
• Compact SOIC Package: 4.9mm × 5.99mm × 1.45mm dimensions with tight tolerances (±0.1mm L/H, ±0.2mm D).
• High Power Density: 0.4W total dissipation (0.05W per resistor) in a small footprint.
• Automation-Friendly: Gull-wing leads and 1.27mm pitch for reliable surface-mount placement.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial environments.
• Non-Automotive (PPAP No): Best suited for industrial, telecom, and instrumentation applications.

GS4B034220FCT Applications

This resistor network excels in:

• Voltage Division & Pull-Up/Down Circuits: Precision-matched resistors ensure consistent performance in analog/digital interfaces.
• Signal Conditioning: Stable thin-film technology minimizes drift in sensor interfaces (e.g., RTDs, bridges).
• Industrial Control Systems: Robust ceramic construction withstands harsh environments (e.g., PLCs, motor drives).
• Telecom Hardware: Low TCR (±25ppm/°C) maintains accuracy in frequency-sensitive RF/analog modules.
• Test & Measurement Equipment: High tolerance (1%) and low thermal drift critical for calibration circuits.

Conclusion of GS4B034220FCT

The GS4B034220FCT combines precision, power efficiency, and compactness, making it a standout choice for engineers needing reliable resistor networks in space-constrained, thermally challenging designs. Its thin-film technology, tight tolerances, and robust packaging offer superior performance over thick-film alternatives, particularly in industrial and precision electronics. While not PPAP-compliant, it is ideal for non-automotive applications demanding long-term stability and repeatability.
