GQ8A034420GAT Description

The GQ8A034420GAT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, this 16-pin SMD component offers a 442Ω resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its isolated (ISOL) circuit design provides independent resistors, making it ideal for signal conditioning and voltage division. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling and compactness (4.9mm × 6.02mm × 1.47mm).

GQ8A034420GAT Features

• Thin-film technology: Delivers superior accuracy and long-term reliability compared to thick-film alternatives.
• Ceramic case: Enhances thermal performance and mechanical durability in harsh environments.
• Gull-wing termination: Facilitates robust surface-mount assembly (SMD) with a 0.64mm pitch for high-density PCBs.
• Non-automotive, non-PPAP: Suited for industrial and commercial applications where automotive-grade certification isn’t required.
• EU RoHS non-compliant: Note for applications exempt from RoHS restrictions.
• Tube packaging: Protects components during handling and assembly.

GQ8A034420GAT Applications

This resistor network excels in:

• Precision analog circuits: Voltage dividers, feedback networks, and sensor interfaces in test/measurement equipment.
• Signal isolation: Isolated signal paths in communication modules or data acquisition systems.
• High-temperature environments: Industrial controls, power supplies, and aerospace systems due to its 125°C max operating temperature.
• Space-constrained designs: QSOP package optimizes board real estate without compromising performance.
