GQCB011431CAT Description

The GQCB011431CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 23-resistor array features a 1.43KΩ resistance value with an ultra-tight 0.25% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (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 supports 100V maximum voltage. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the rectangular ceramic case enhances thermal and mechanical reliability.

GQCB011431CAT Features

• Precision Performance: 0.25% tolerance and ±100ppm/°C TCR for high-accuracy signal conditioning.
• Robust Construction: Ceramic QSOP package ensures durability and heat dissipation in harsh environments.
• Space-Efficient: Compact 8.66mm × 6.02mm × 1.47mm footprint with 0.64mm terminal pitch for high-density layouts.
• Wide Operating Range: Rated for 125°C maximum temperature and derated power up to 125°C.
• Automated Assembly: Gull-wing SMD termination compatible with pick-and-place processes.
• Non-Automotive: Suitable for industrial and commercial applications (PPAP not required).

GQCB011431CAT Applications

This resistor network excels in precision analog circuits, including:

• Voltage dividers and sensor signal conditioning in test/measurement equipment.
• Feedback networks for op-amps and ADCs/DACs in data acquisition systems.
• Impedance matching in communication hardware (e.g., RF modules).
• Medical devices requiring stable, low-drift resistance values.
• Industrial control systems where ceramic packaging mitigates thermal stress.
