GQCA021802GT

GQCA021802GT Description

The GQCA021802GT 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 18KΩ resistors with a tight 2% tolerance and ±50ppm/°C temperature coefficient, ensuring reliable operation in demanding environments. Encased in a ceramic substrate, it offers superior thermal conductivity and mechanical durability. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, it suits both industrial and commercial circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the tube packaging ensures handling efficiency.

GQCA021802GT Features

• Precision Thin Film Technology: Delivers low noise and high stability (±50ppm/°C) for signal integrity.
• Isolated Resistor Network (ISOL): 12 independent resistors prevent cross-talk in sensitive circuits.
• Ceramic Case: Enhances heat dissipation and withstands temperatures up to 125°C.
• QSOP Package: Compact 8.66mm × 6.02mm × 1.47mm footprint with 0.64mm pitch, ideal for high-density PCBs.
• Derated Power Handling: Operates at 70–125°C with derated power, ensuring reliability under thermal stress.
• Non-Automotive (PPAP No): Optimized for industrial controls, test equipment, and telecom infrastructure.

GQCA021802GT Applications

• Signal Conditioning: Precision voltage dividers in ADC/DAC circuits.
• Medical Electronics: Isolated feedback networks in diagnostic equipment.
• Telecom Hardware: Impedance matching in RF modules and base stations.
• Test & Measurement: Calibration circuits requiring long-term stability.
• Industrial Automation: PLCs and sensor interfaces where thermal drift is critical.

Conclusion of GQCA021802GT

The GQCA021802GT excels in applications demanding high precision, thermal resilience, and compact integration. Its ceramic construction, isolated design, and thin-film technology provide a competitive edge over polymer-based networks or lower-tolerance arrays. While non-compliant with EU RoHS, it remains a robust choice for non-consumer systems. Engineers will value its balance of power handling, size, and performance in mission-critical electronics.
