GQCB021580GT

GQCB021580GT Description

The GQCB021580GT 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 158Ω resistance value per resistor with a tight 2% tolerance and a low ±50ppm/°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 applications. 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.
