GQCB021432GDT Description

The GQCB021432GDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. It features 23 resistors with a 14.3KΩ resistance value, 2% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a 24-pin QSOP ceramic package, this surface-mount (SMD) network offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuit designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB integration, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) optimize space efficiency.
