GQ8A014221JFT Description

The GQ8A014221JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-resistor network features a 4.22KΩ resistance per element with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring consistent performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation and 0.1W (1/10W) per resistor, making it suitable for compact, high-density PCB designs. The gull-wing termination and surface-mount (SMD) configuration facilitate automated assembly, while the 100V maximum voltage rating enhances durability in demanding circuits.

GQ8A014221JFT Features

• Isolated Resistor Network: Each of the 8 resistors is electrically isolated (designated ISOL), reducing crosstalk in sensitive analog/digital systems.
• Ceramic QSOP Package: Provides superior thermal stability and mechanical robustness compared to plastic alternatives.
• Thin-Film Technology: Delivers low noise, high accuracy, and long-term reliability, ideal for precision instrumentation.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated above 70°C), suited for industrial and automotive environments (though not PPAP/automotive-certified).
• Compact Dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth) for space-constrained layouts.

GQ8A014221JFT Applications

This resistor network excels in:

• Signal Conditioning: Isolation of ADC/DAC reference circuits in data acquisition systems.
• Voltage Division: Precision dividers in sensor interfaces or feedback loops.
• Industrial Controls: PLCs, motor drives, and power supplies requiring stable resistance under thermal stress.
• Medical Electronics: Patient monitoring equipment where low drift and reliability are critical.
• Test & Measurement: Calibration circuits and instrumentation amplifiers.
