GQ8A022320FAT Description

The GQ8A022320FAT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers 232Ω resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The isolated (ISOL) circuit design provides independent resistors, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling and compactness in a 4.9mm × 6.02mm × 1.47mm surface-mount form factor.

GQ8A022320FAT Features

• Precision Thin Film Technology: Delivers stable performance with low TCR (±50ppm/°C) and 1% tolerance.
• Robust Ceramic QSOP Package: Enhances thermal management and durability in harsh environments.
• Isolated Resistor Network (ISOL): Each of the 8 resistors operates independently, reducing crosstalk.
• High Power Density: 0.75W total power (0.1W per resistor) in a compact 16-pin gull-wing SMD package.
• Wide Temperature Range: Reliable operation from 70°C to 125°C with derated power.
• Automotive-Grade Alternatives: While not PPAP or automotive-qualified, its ceramic construction suits industrial and telecom applications.

GQ8A022320FAT Applications

• Signal Conditioning: Precision voltage dividers and feedback networks in analog circuits.
• Medical Equipment: Isolated resistor networks for patient monitoring devices.
• Industrial Controls: High-reliability systems requiring stable resistance under thermal stress.
• Telecom Infrastructure: RF and baseband signal processing where low TCR is critical.
• Test & Measurement: Calibration circuits due to its tight tolerance and low drift.

Conclusion of GQ8A022320FAT

The GQ8A022320FAT excels in precision analog designs where isolated resistors, thermal stability, and compact power handling are paramount. Its ceramic QSOP package and thin-film technology make it a superior choice over polymer-based networks in high-temperature or high-reliability scenarios. While not RoHS-compliant, it remains a robust solution for industrial, medical, and telecom applications demanding long-term accuracy.
