GS4B0156R2DDT Description

The GS4B0156R2DDT 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 56.2Ω resistance per resistor, it offers a tight ±0.5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. The ceramic case and gull-wing termination provide robust mechanical and thermal stability, while the 0.4W total power rating (0.05W per resistor) makes it suitable for low-power circuits. Its 100V maximum voltage rating and 1.27mm terminal pitch enhance compatibility with high-density PCB designs.

GS4B0156R2DDT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Compact SOIC Package: 4.9mm × 5.99mm × 1.45mm dimensions with ±0.1mm length/height tolerances for space-constrained designs.
• High Reliability: Ceramic substrate ensures excellent thermal dissipation and durability in harsh environments.
• Automated Assembly Friendly: Gull-wing leads enable smooth pick-and-place SMD processes.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and instrumentation applications where PPAP compliance isn’t required.

GS4B0156R2DDT Applications

This resistor network excels in:

• Voltage Division & Bus Termination: The BUS circuit designator ensures minimal signal reflection in high-speed data lines.
• Precision Analog Circuits: Suitable for op-amp feedback networks, DAC/ADC interfaces, and sensor signal conditioning.
• Power Management Modules: Stable performance in DC-DC converters and voltage references.
• Test & Measurement Equipment: Low TCR (±100ppm/°C) minimizes drift in calibrated systems.

Conclusion of GS4B0156R2DDT

The GS4B0156R2DDT combines precision, compactness, and reliability, making it a standout choice for engineers needing stable resistor networks in industrial electronics, communication systems, and precision instrumentation. While not RoHS-compliant, its ceramic construction and thin-film technology offer superior performance over standard thick-film arrays, particularly in thermal and electrical stability. For designs demanding tight tolerances and robust SMD integration, this model delivers exceptional value.
