GQ0A034020GAT Description

The GQ0A034020GAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 10-resistor array features a 402Ω resistance value with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (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 demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical reliability.
