GQCA014421GFT Description

The GQCA014421GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and thermal performance. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 4.42KΩ 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 ±100ppm/°C temperature coefficient guarantees minimal resistance drift across its operating range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for durability in compact, high-density PCB layouts.

GQQCA014421GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Design (ISOL): Each of the 12 resistors operates independently, reducing crosstalk in multi-channel systems.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical strength compared to polymer-based alternatives.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• QSOP Gull-Wing Termination: Facilitates automated assembly and inspection, with a 0.64mm terminal pitch for space-constrained designs.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and instrumentation applications where automotive compliance isn’t required.

GQCA014421GFT Applications

This resistor network excels in:

• Signal Conditioning Circuits: Precision voltage dividers or feedback networks in op-amp configurations.
• Medical Equipment: Isolated measurement channels in patient monitoring systems.
• Test & Measurement Instruments: High-accuracy calibration and sensor interfacing.
• Telecom Infrastructure: Line termination and impedance matching in high-frequency modules.
• Industrial Control Systems: Robust performance in PLCs and motor drive circuits.

Conclusion of GQCA014421GFT
