GQ8B021911JDT Description

The GQ8B021911JDT 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 with a 1.91KΩ resistance value, offering a 5% tolerance and a ±50ppm/°C temperature coefficient. Encased in a ceramic package, it ensures excellent thermal stability and durability. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in surface-mount (SMD) designs. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.

GQ8B021911JDT Features

• Circuit Designator: BUS configuration for streamlined signal routing.
• Thin-Film Technology: Delivers superior accuracy and low noise compared to thick-film alternatives.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ensuring stability in harsh environments.
• Compact Dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Non-Automotive, Non-PPAP: Ideal for industrial and commercial applications where automotive-grade certification isn’t required.
• High Power Density: 0.75W total dissipation in a miniature QSOP footprint, optimizing board space.
