GQCB011911JDT Description

The GQCB011911JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 23-resistor array features a 1.91KΩ resistance value per resistor 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 compact rectangular footprint (8.66mm x 6.02mm x 1.47mm) with gull-wing SMD termination for reliable surface mounting. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, this non-automotive, non-PPAP component is ideal for industrial and commercial applications where space efficiency and thermal stability are critical.
