GQCA0156R0GT

GQCA0156R0GT Description

The GQCA0156R0GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 56Ω resistance value and a tight 2% tolerance. Built on a ceramic substrate, it offers excellent thermal stability with a ±100ppm/°C temperature coefficient, ensuring reliable performance across a -70°C to +125°C operating range. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.
