GQ8B0142R2GDT Description

The GQ8B0142R2GDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for surface-mount applications. It features 15 resistors in a 16-pin QSOP package with a 42.2Ω resistance value, 2% tolerance, and a ±100ppm/°C temperature coefficient. The ceramic case ensures durability and thermal stability, while the gull-wing termination facilitates reliable PCB mounting. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, this component is engineered for moderate-power circuits. Its compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.

GQ8B0142R2GDT Features

• Thin-Film Technology: Delivers low noise and high stability for precision applications.
• Ceramic Case: Enhances heat dissipation and mechanical robustness.
• BUS Circuit Design: Optimized for bus termination, pull-up/pull-down networks, and voltage division.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, suitable for industrial environments.
• QSOP Package: Gull-wing leads ensure reliable surface-mount soldering with a 0.64mm terminal pitch.
• Non-Automotive Grade: Ideal for consumer electronics, telecom, and industrial controls where PPAP compliance isn’t required.

GQ8B0142R2GDT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage division in ADC/DAC circuits.
• Bus Termination: DDR memory, CAN bus, and SPI/I²C interfaces to reduce reflections.
