GQ0A022490JT

GQ0A022490JT Description

The GQ0A022490JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and isolation. This 10-resistor array features a 249Ω resistance value per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a 70°C to 125°C operating range. 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 its isolated (ISOL) circuit designator ensures independent resistor functionality.
