GQ0A034220FT Description

The GQ0A034220FT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 10-resistor isolated network features a 422Ω resistance per resistor with a tight 1% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 20-pin QSOP ceramic package, it offers excellent thermal stability and mechanical durability, making it suitable for demanding environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor) ensure robust operation in compact circuits.
