GQCA0390R9JFT Description

The GQCA0390R9JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and low thermal drift. This 24-pin QSOP package integrates 12 isolated resistors, each with a 90.9Ω resistance value and a tight ±5% tolerance. The ceramic case ensures excellent thermal stability, while the thin-film technology delivers ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is suited for demanding circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
