GQ0A034700DBT Description

The GQ0A034700DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 10-resistor array features a 470Ω resistance value per resistor with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 20-pin QSOP ceramic package, it offers 1W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical reliability.
