GQ0A0354R9GDT Description

The GQ0A0354R9GDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP device integrates 10 isolated resistors, each with a 54.9 Ω resistance value and a tight 2% tolerance. The ceramic-based construction ensures excellent thermal stability, with a low ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. Rated for 1W total power dissipation (0.1W per resistor) and 100V maximum voltage, it operates reliably across a 70°C to 125°C derated power range, with a 125°C maximum operating temperature. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
