GQ8B018202GDT Description

The GQ8B018202GDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 82K Ohm resistance value and a tight 2% tolerance, ensuring consistent performance across all channels. Built on a ceramic substrate, it offers excellent thermal stability with a ±100ppm/°C temperature coefficient, making it suitable for environments with fluctuating temperatures. The network operates within a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C and a 100V maximum voltage rating. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the 0.64mm terminal pitch ensures compatibility with high-density layouts.

GQ8B018202GDT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog and digital circuits.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical durability.
• High Power Handling: 0.75W (3/4W) total power rating (0.05W per resistor) for reliable operation in power-sensitive designs.
• Compact QSOP Package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth) for space-constrained applications.
• BUS Circuit Designator: Optimized for bus termination, voltage division, and pull-up/pull-down networks.
• Non-Automotive, Non-PPAP: Ideal for industrial, telecom, and instrumentation use where automotive compliance is not required.
