GQCB011691JCT Description

The GQCB011691JCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 1.69KΩ resistance value per element with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 24-pin QSOP ceramic package, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the rectangular ceramic case enhances thermal and mechanical durability.

GQCB011691JCT Features

• High-Density Integration: 23 resistors in a compact QSOP-24 package (8.66mm × 6.02mm × 1.47mm) save board space.
• Robust Construction: Ceramic substrate ensures superior heat dissipation and reliability in harsh environments.
• Precision Performance: Thin-film technology delivers low noise and tight tolerance (±5%), ideal for analog signal conditioning.
• Wide Operating Range: Stable across -70°C to +125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/AEC-Q200 qualified).
• Automated Assembly Friendly: Gull-wing leads and 0.64mm pitch enable high-speed SMT processes.

GQCB011691JCT Applications

This resistor network excels in:

• Voltage Division & Bus Termination: The BUS circuit designator indicates optimization for digital bus lines (e.g., I²C, SPI).
• Sensor Interface Circuits: Low TCR (±100ppm/°C) minimizes drift in precision measurement systems.
• Industrial Control Systems: Ceramic packaging resists vibration and thermal cycling in PLCs and motor drives.
• Test & Measurement Equipment: Thin-film technology ensures repeatability in calibration circuits.

Conclusion of GQCB011691JCT

The GQCB011691JCT combines high-density integration, ceramic ruggedness, and thin-film precision, making it a standout choice for engineers needing reliable resistor networks in space-constrained, thermally challenging designs. While not automotive-grade, its 125°C rating and low TCR suit industrial, telecom, and instrumentation applications where stability and durability are critical. The tube packaging further streamlines production handling for medium-to-high-volume manufacturing.
