GQCB011911DT Description

The GQCB011911DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 23-resistor array features a 1.91KΩ resistance value per resistor with a tight 0.5% tolerance and a low ±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 high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) save board space.

GQCB011911DT Features

• Precision Thin Film Technology: Delivers high accuracy (±0.5%) and low TCR (±100ppm/°C) for stable performance in varying environments.
• Robust Ceramic Case: Enhances thermal stability and durability, ideal for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• High-Density Integration: 23 resistors in a 24-pin QSOP package optimize space efficiency without compromising performance.
• Wide Operating Range: Functions reliably from -55°C to 125°C, with derated power up to 125°C.
• Surface-Mount Gull Wing Terminals: Ensures secure PCB attachment and compatibility with automated assembly processes.
