GQCB019101GDT Description

The GQCB019101GDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 9.1K Ohm resistance value with a tight 2% 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 maximum voltage rating of 100V. Its gull-wing termination and surface-mount design make it ideal for automated assembly processes. The ceramic case style enhances thermal stability, while the rectangular package (8.66mm x 6.02mm x 1.47mm) ensures compact PCB integration.
