GQ0A0190R9DT Description

The GQ0A0190R9DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a 90.9 Ω resistance, a tight ±0.5% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a ceramic package, it ensures superior thermal stability and durability, making it ideal for environments with elevated operating temperatures (up to 125°C). The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating provide robust performance in compact, surface-mount designs.

GQQ0A0190R9DT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Resistor Network (ISOL): Each of the 10 resistors is electrically isolated, enabling flexible circuit design.
• High-Temperature Resilience: Operates reliably from 70°C to 125°C with derated power.
• Compact & Robust: 8.66mm × 6.02mm × 1.47mm ceramic QSOP package with gull-wing terminations for secure SMD mounting.
• Low TCR (±100ppm/°C): Minimizes resistance drift across temperature variations.
• 0.64mm Terminal Pitch: Facilitates high-density PCB layouts.

GQ0A0190R9DT Applications

This resistor network excels in precision analog and mixed-signal systems, including:

• Industrial Automation: Signal isolation in PLCs and sensor interfaces.
• Medical Electronics: High-reliability circuits in diagnostic equipment.
• Telecommunications: Impedance matching and termination in RF modules.
• Test & Measurement: Calibration and reference circuits requiring low drift.
• Aerospace & Defense: Ruggedized electronics where temperature stability is critical.
