GQCB011431BT Description

The GQCB011431BT 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 0.1% 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 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.
