GS4B029761DAT Description

The GS4B029761DAT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. Housed in an 8-pin SOIC ceramic package, it features a 9.76KΩ resistance value with a tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this component is engineered for reliability in demanding circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.

GS4B029761DAT Features

• Precision Thin Film Technology: Delivers low noise and high stability, ideal for sensitive analog circuits.
• Compact SOIC Package: 4.9mm × 5.99mm × 1.45mm dimensions with tight tolerances (±0.1mm length/height, ±0.2mm depth) suit space-constrained designs.
• Robust Construction: Ceramic substrate ensures superior heat dissipation and longevity vs. polymer-based networks.
• BUS Circuit Designator: Optimized for bus termination, voltage division, or pull-up/down applications in digital systems.
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation use where PPAP compliance is not required.

GS4B029761DAT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision dividers in sensor interfaces or data acquisition systems.
• Digital Bus Termination: Mitigating signal reflections in high-speed communication lines (e.g., SPI, I²C).
• Power Management Circuits: Voltage reference networks in DC-DC converters or LDO regulators.
• Test & Measurement Equipment: Where low TCR and tight tolerance are critical for accuracy.

Conclusion of GS4B029761DAT

The GS4B029761DAT combines precision, compactness, and ruggedness, making it a standout choice for engineers needing reliable resistor networks in industrial electronics, telecom infrastructure, and precision instrumentation. Its ceramic SOIC package and thin film technology offer distinct advantages over epoxy-based alternatives, particularly in thermal performance and long-term stability. While not RoHS-compliant, its 0.5% tolerance and ±50ppm/°C TCR ensure consistent operation in environments with fluctuating temperatures. Ideal for high-reliability SMT designs where space and performance are paramount.
