GQCA021870DCT

GQCA021870DCT Description

The GQCA021870DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 187Ω resistance value and an exceptional ±0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±50ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) integration, while the 1W total power rating (0.1W per resistor) makes it suitable for power-sensitive designs.

GQCA021870DCT Features

• Precision Performance: 0.5% tolerance and ±50ppm/°C TCR ensure minimal drift in high-accuracy circuits.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• Isolated Design: 12 independent resistors (ISOL circuit designator) prevent crosstalk in signal conditioning.
• High Voltage Handling: 100V maximum rating supports industrial and telecom applications.
• Compact & Reliable: QSOP package (8.66mm x 6.02mm x 1.47mm) with ±0.1mm dimensional tolerances for consistent PCB assembly.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for harsh environments.

GQCA021870DCT Applications

This resistor network excels in:

• Analog Signal Processing: Precision dividers, DAC/ADC reference circuits.
• Industrial Controls: PLCs, sensor interfaces requiring low drift.
• Telecommunications: RF matching networks, line termination.
• Medical Equipment: High-reliability instrumentation.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical systems.

Conclusion of GQCA021870DCT

The GQCA021870DCT stands out for its combination of precision, isolation, and ruggedness, making it a top choice for engineers prioritizing stability in compact designs. While not PPAP or automotive-qualified, its ceramic thin-film technology and QSOP form factor offer a competitive edge in industrial, medical, and telecom applications where accuracy and thermal performance are critical. For non-automotive high-reliability needs, this model delivers exceptional value.
