GQ8B021800FDT Description

The GQ8B021800FDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 180Ω resistance value and a tight 1% tolerance, ensuring consistent performance in demanding circuits. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. The gull-wing termination facilitates reliable surface-mount (SMD) assembly, while the 0.64mm terminal pitch ensures compatibility with high-density PCB layouts.

GQ8B021800FDT Features

• Precision Thin Film Technology: Delivers ±50ppm/°C temperature coefficient, minimizing resistance drift under thermal stress.
• Robust Power Handling: 0.75W (3/4W) total power rating, with 0.05W (1/20W) per resistor, ideal for distributed power dissipation.
• High Voltage Tolerance: Supports up to 100V maximum voltage, suitable for industrial and instrumentation applications.
• Compact & Reliable: Ceramic case enhances thermal conductivity and mechanical strength, while the QSOP package (4.9mm x 6.02mm x 1.47mm) saves board space.
• BUS Circuit Designator: Optimized for bus termination, pull-up/pull-down networks, and voltage division in digital systems.
