GQCA0156R2GGT

GQCA0156R2GGT Description

The GQCA0156R2GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and isolation. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 56.2Ω resistance value and a tight 2% tolerance. Encased in a ceramic package, it offers superior thermal stability with a ±100ppm/°C temperature coefficient and operates reliably across a wide temperature range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, it is engineered for demanding surface-mount (SMD) applications. The gull-wing termination ensures secure PCB mounting, while the QSOP package (8.66mm x 6.02mm x 1.47mm) optimizes space efficiency.

GQCA0156R2GGT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Resistor Network (ISOL): 12 independent resistors prevent crosstalk, ideal for signal conditioning.
• Ceramic Case: Enhances thermal dissipation and mechanical robustness.
• Wide Operating Range: -70°C to +125°C with derated power up to 125°C.
• High Power Density: 1W total power (0.1W per resistor) in a compact QSOP footprint.
• Gull-Wing Termination: Facilitates reliable soldering and inspection in automated assembly.
• Low TCR (±100ppm/°C): Minimizes resistance drift under thermal stress.

GQCA0156R2GGT Applications

This resistor network excels in:

• Industrial Control Systems: Precision voltage dividers, feedback loops, and sensor interfaces.
• Medical Electronics: Isolated signal paths in diagnostic equipment.
• Telecommunications: Impedance matching and termination in high-frequency circuits.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical modules.
• Test & Measurement Equipment: Calibration and reference circuits requiring stable resistance.

Conclusion of GQCA0156R2GGT

The GQCA0156R2GGT stands out for its combination of precision, isolation, and power handling in a compact ceramic QSOP package. Its thin-film construction and low TCR make it a superior choice over thick-film alternatives in environments with thermal fluctuations. While not PPAP or automotive-qualified, it is well-suited for industrial, medical, and telecom applications demanding reliability and space efficiency. Engineers will appreciate its balance of performance and manufacturability, particularly in high-density PCB designs.
