GQCA0161R9GT

GQCA0161R9GT Description

The GQCA0161R9GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and tight tolerances. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 61.9Ω resistance value and a 2% 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 ±100ppm/°C temperature coefficient. The gull-wing termination enables reliable surface-mount (SMD) assembly, while the 0.1W power rating per resistor (1W total) and 100V maximum voltage rating make it suitable for low-power, high-voltage environments.

GQCA0161R9GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): 12 independent resistors minimize crosstalk in multi-channel systems.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical strength compared to plastic alternatives.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial environments.
• Compact QSOP Form Factor: 8.66mm x 6.02mm footprint with 0.64mm terminal pitch, saving PCB space.
• Gull-Wing SMD Termination: Ensures secure soldering and compatibility with automated assembly processes.
• Non-Automotive (PPAP No): Optimized for commercial/industrial use, though not automotive-grade.
