GQ8A0149R9JGT Description

The GQ8A0149R9JGT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance and thermal performance. Encased in a ceramic QSOP package, this 16-pin SMD component offers a 49.9Ω resistance per resistor with a 5% tolerance and ±100ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports moderate power dissipation while maintaining isolation between resistors. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface mounting, and its compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.

GQ8A0149R9JGT Features

• Isolated Resistor Network: Each of the 8 resistors is electrically isolated, reducing crosstalk in sensitive circuits.
• High-Temperature Stability: Operates reliably up to 125°C with derated power performance.
• Precision Thin-Film Technology: Delivers low noise and high accuracy (±100ppm/°C) for signal conditioning.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical durability.
• Surface-Mount Design: Gull-wing leads and QSOP-16 footprint ensure compatibility with automated assembly.
• Moderate Power Handling: 0.75W total rating (0.1W per resistor) suits a range of analog and digital applications.

GQ8A0149R9JGT Applications

This resistor network excels in:

• Industrial Control Systems: Signal isolation and voltage division in PLCs and sensors.
• Medical Electronics: Precision instrumentation requiring stable resistance under thermal stress.
• Telecommunications: Impedance matching and termination in high-frequency circuits.
• Automotive (Non-Automotive Rated): Non-safety-critical applications like infotainment systems.
• Test & Measurement Equipment: Calibration and reference circuits due to its low TCR.
