GQCA0364R9GFT Description

The GQCA0364R9GFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each with a 64.9Ω resistance value and a tight 2% tolerance, ensuring consistent performance in precision circuits. The ceramic case construction enhances thermal stability, while the thin-film technology delivers excellent ±25ppm/°C temperature coefficient, minimizing resistance drift over temperature variations. Rated for 1W total power dissipation (0.1W per resistor) and 100V maximum voltage, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments.

GQCA0364R9GFT Features

• High Isolation Design: Ideal for ISOL (isolation) circuit applications, reducing crosstalk and interference.
• Robust Construction: Ceramic substrate ensures superior thermal management and mechanical durability.
• Precision Performance: ±25ppm/°C TCR and 2% tolerance provide stable resistance under varying conditions.
• Compact & Reliable: QSOP-24 gull-wing SMD package (8.66mm x 6.02mm x 1.47mm) saves board space while supporting automated assembly.
• Wide Operating Range: Derated power capability up to 125°C suits industrial and automotive-adjacent applications (though not PPAP/AEC-Q200 qualified).

GQCA0364R9GFT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
• Isolation Circuits: Buffering and decoupling in data acquisition systems, medical instrumentation, and test equipment.
• Industrial Controls: PLCs, sensor interfaces, and power supply monitoring where stability and isolation are critical.
• Telecom & Networking: Line termination, impedance matching in high-frequency PCBs.

Conclusion of GQCA0364R9GFT

The GQCA0364R9GFT stands out for its combination of precision, isolation, and ruggedness, leveraging thin-film technology and ceramic packaging for reliable performance in precision electronics. While not automotive-grade, its wide temperature range and low TCR make it a versatile choice for industrial, telecom, and instrumentation designs requiring stable, high-density resistor networks. The QSOP-24 form factor further ensures compatibility with space-constrained, high-reliability applications.
