GQCA0256R0DCT

GQCA0256R0DCT Description

The GQCA0256R0DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 56Ω resistance value and a tight ±0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) compatibility, while the ±50ppm/°C temperature coefficient guarantees minimal resistance drift across a wide 70°C to 125°C derated power range.

GQCA0256R0DCT Features

• High Precision: 0.5% tolerance and ±50ppm/°C TCR ensure consistent performance in precision circuits.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• Isolated Resistors: 12 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel applications.
• Power Handling: 0.1W per resistor (1W total) with a 100V maximum voltage rating.
• Compact & Reliable: QSOP package (8.66mm × 6.02mm × 1.47mm) with ±0.1mm height/length tolerances for high-density PCB layouts.
• Industrial-Grade: Suitable for non-automotive applications, though PPAP and RoHS non-compliance may limit certain uses.

GQCA0256R0DCT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers and feedback networks in op-amp circuits.
• Medical Equipment: High-accuracy analog front-ends where low drift and isolation are critical.
• Test & Measurement: Calibration circuits and sensor interfaces requiring stable resistance values.
• Industrial Controls: Isolated signal paths in PLC modules or DAC/ADC systems.
• Aerospace & Defense: Ruggedized electronics benefiting from ceramic-packaged reliability.

Conclusion of GQCA0256R0DCT

The GQCA0256R0DCT stands out for its precision, isolation, and ceramic-enhanced durability, making it ideal for high-reliability analog designs. While not suited for automotive or RoHS-restricted applications, its thin-film technology and gull-wing SMD compatibility ensure superior performance in industrial, medical, and instrumentation systems. Engineers seeking a stable, space-saving resistor network with low TCR and tight tolerances will find this model a compelling choice.
