GQCB011431FDT Description

The GQCB011431FDT 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 a tight 1% 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 precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the rectangular ceramic case enhances thermal and mechanical stability.

GQCB011431FDT Features

• High-Density Integration: 23 resistors in a compact QSOP-24 package (8.66mm x 6.02mm x 1.47mm) save board space.
• Superior Stability: Thin-film technology and ±100ppm/°C TCR ensure minimal drift under thermal stress.
• Robust Construction: Ceramic substrate provides excellent heat dissipation and durability.
