GQCA011331GFT Description

The GQCA011331GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and thermal performance. This 24-pin QSOP package integrates 12 isolated resistors, each rated at 1.33KΩ ±2% tolerance, with a ±100ppm/°C temperature coefficient, ensuring reliable operation across a 70°C to 125°C derated power range. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the 0.1W (1/10) power rating per resistor and 1W total power rating make it suitable for distributed power dissipation.

GQCA011331GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Resistor Design (ISOL): Each of the 12 resistors operates independently, reducing crosstalk.
• Wide Temperature Range: Operates up to 125°C with derated performance up to 70°C.
• Compact & Robust: 8.66mm x 6.02mm x 1.47mm QSOP package with ±0.1mm length/height tolerances for tight PCB layouts.
• High Voltage Tolerance: Supports 100V maximum rating, ideal for industrial and telecom applications.
• Non-Automotive Grade: Optimized for general-purpose use; PPAP and RoHS non-compliant.

GQCA011331GFT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers and feedback networks in analog circuits.
• Industrial Controls: Isolated measurement systems and sensor interfaces requiring thermal stability.
• Telecom Hardware: Line termination and impedance matching in high-frequency modules.
• Test & Measurement Equipment: Calibration circuits where tolerance and TCR are critical.
• Power Management: Distributed load sharing in low-power DC/DC converters.

Conclusion of GQCA011331GFT

The GQCA011331GFT stands out for its isolated thin-film resistors, tight tolerances, and ceramic QSOP package, making it a reliable choice for precision electronics. While not suited for automotive or RoHS-restricted designs, its 2% tolerance, ±100ppm/°C TCR, and 100V rating ensure performance in demanding industrial, telecom, and instrumentation applications. Its gull-wing termination and surface-mount compatibility further simplify high-density PCB integration.
