GQCA021691GFT Description

The GQCA021691GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and tight tolerances. This 24-pin QSOP package features 12 isolated resistors, each with a 1.69KΩ resistance and a 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. With a ±50ppm/°C temperature coefficient, this network maintains accuracy across a wide operating temperature range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. Rated for 100V maximum voltage and 1W total power dissipation, it offers a balance of durability and efficiency.

GQCA021691GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Configuration (ISOL): Each of the 12 resistors operates independently, reducing crosstalk in multi-channel systems.
• High Power Handling: 0.1W per resistor (1W total) with derating up to 125°C ensures reliability under load.
• Compact QSOP Package: 8.66mm x 6.02mm footprint with a low 1.47mm profile, ideal for space-constrained PCBs.
• Automated Assembly Friendly: Gull-wing leads and ±0.1mm dimensional tolerances facilitate precise SMD placement.
• Non-Automotive, Non-PPAP: Optimized for industrial/commercial use where PPAP compliance isn’t required.

GQCA021691GFT Applications

• Signal Conditioning: Isolated resistor networks are critical in op-amp feedback circuits and sensor interfaces.
• Medical Equipment: Stable performance suits patient monitoring devices and diagnostic instruments.
• Test & Measurement Systems: Low TCR (±50ppm/°C) ensures accuracy in calibration tools and data acquisition modules.
• Telecom Infrastructure: Used in line drivers, filters, and impedance matching networks for signal integrity.
• Industrial Controls: Reliable operation in PLCs and motor drives where temperature variations are common.
