GQ8A022152CT Description

The GQ8A022152CT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it features 21.5KΩ resistors with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount (SMD) network is ideal for precision analog and mixed-signal circuits. Its gull-wing termination and ceramic case provide robust mechanical and thermal performance, while the isolated (ISOL) circuit design minimizes crosstalk.

GQ8A022152CT Features

• High Precision: ±0.25% tolerance and ±50ppm/°C TCR for stable performance.
• Robust Construction: Ceramic QSOP package ensures durability and heat dissipation.
• Isolated Resistors: Independent 21.5KΩ resistors reduce interference in critical paths.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated above 70°C).
• Surface-Mount Ready: Gull-wing terminals with 0.64mm pitch for easy PCB integration.
• High Voltage Handling: Supports up to 100V, suitable for industrial and instrumentation use.
• Low Crosstalk: Isolated design minimizes signal coupling in dense layouts.

GQ8A022152CT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor conditioning.
• Industrial Controls: PLCs, motor drives, and power management systems requiring isolation.
• Test & Measurement Equipment: High-accuracy signal chains and calibration modules.
• Medical Electronics: Isolated patient monitoring and diagnostic devices.
• Automotive (Non-Automotive Rated): Prototyping or benign-environment automotive subsystems.

Conclusion of GQ8A022152CT

The GQ8A022152CT combines precision, isolation, and ruggedness in a compact QSOP format, making it a standout choice for engineers needing reliable thin-film networks. Its ceramic construction, low TCR, and high voltage tolerance address challenges in industrial, medical, and instrumentation designs. While not PPAP or automotive-qualified, its performance suits high-reliability prototypes and non-critical automotive applications. For isolation-critical circuits demanding tight tolerances, this network delivers exceptional value.
