GQCA031690GT

GQCA031690GT Description

The GQCA031690GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 24-pin QSOP package features 12 isolated resistors, each with a 169Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across its operating range of -70°C to +125°C. With a 100V maximum voltage rating and 0.1W power dissipation per resistor, this network is ideal for analog signal conditioning, isolation circuits, and precision voltage division.

GQCA031690GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive applications.
• Isolated Resistor Design (ISOL): Each of the 12 resistors operates independently, reducing crosstalk.
• Robust Ceramic Package: Enhances thermal performance and mechanical durability.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power.
• Compact QSOP Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions save PCB space.
• Gull-Wing Termination: Ensures secure soldering and compatibility with automated assembly.
• Low TCR (±25ppm/°C): Minimizes resistance variation under thermal stress.

GQCA031690GT Applications

This resistor network excels in:

• Industrial Control Systems: Signal isolation and conditioning in PLCs and sensors.
• Medical Electronics: Precision analog circuits in diagnostic equipment.
• Telecommunications: Impedance matching and filtering in RF modules.
• Automotive (Non-Automotive Grade): Non-safety-critical circuits like infotainment systems.
• Test & Measurement Equipment: Calibration and reference networks requiring low drift.

Conclusion of GQCA031690GT

The GQCA031690GT combines precision, isolation, and compactness, making it a standout choice for engineers needing reliable resistor networks in space-constrained, high-stability designs. While not PPAP or RoHS compliant, its ceramic construction, thin-film accuracy, and wide thermal range offer superior performance in industrial, medical, and telecom applications where resistance consistency is critical. For designs demanding low TCR, high voltage tolerance, and isolated channels, this model provides an optimal balance of functionality and durability.
