GS4B011781JGT

GS4B011781JGT Description

The GS4B011781JGT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 1.78KΩ resistance per element and a ±5% absolute tolerance, this ceramic-based network ensures reliable performance in demanding environments. Its ±100ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for thermally variable circuits. The SOIC-C series construction offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for robust surface-mount assembly. Rated at 0.4W total power (0.05W per resistor) and 100V maximum voltage, it balances power handling with miniaturization.

GS4B011781JGT Features

• Bussed Network Design: Simplifies PCB layout by connecting resistors in a shared topology, reducing component count.
• Thin-Film Technology: Delivers superior stability, low noise, and tight ratio tolerance (±2%) for precision analog/digital circuits.
• Ceramic Substrate: Enhances thermal management and durability in high-temperature environments (70°C to 125°C derated range).
• SOIC Package: Combines space efficiency (1.27mm terminal pitch) with ease of automated assembly.
• Non-Automotive Grade: Ideal for industrial and consumer electronics where PPAP compliance is not required.

GS4B011781JGT Applications

This resistor network excels in:

• Voltage Divider Circuits: Precision attenuation in sensor interfaces or ADC front-ends.
• Bus Termination: Signal integrity preservation in low-power digital systems (e.g., SPI, I²C).
• Industrial Controls: Stable biasing in PLCs or motor drivers, leveraging its wide temperature range.
• Test Equipment: Calibration networks requiring tight tolerance and low drift.

Conclusion of GS4B011781JGT

The GS4B011781JGT stands out for its ceramic-based reliability, thin-film accuracy, and space-saving SOIC footprint. While not RoHS-compliant, its bussed architecture and ±100ppm/°C stability make it a cost-effective choice for non-automotive precision applications. Engineers will value its balance of performance, compactness, and ease of integration in analog signal chains or power distribution networks.
