744314330 Description

Short technical summary and product information.

The Würth Elektronik 744314330 is a shielded wirewound fixed inductor from the WE-HCI series. It offers a nominal inductance of 3.3 µH with ±20% tolerance, tested at 100 kHz and 100 mV. The component is rated for a maximum current of 9 A (ΔT = 50 K) and a performance rated current of 10.9 A (ΔT = 40 K per IEC 62024-2-2020). Typical saturation currents are 3.2 A at 10% inductance drop and 8 A at 30% drop. DC resistance is 9 mOhm ±10% and the self-resonant frequency is 65 MHz.

 

The inductor is housed in a nonstandard 7050 surface mount package measuring 7.0 mm x 6.9 mm with a height of 5.0 mm. It operates over -40°C to +150°C and meets AEC-Q200 qualification for automotive applications. The component is RoHS and REACH compliant with MSL level 1. It is designed for general electronic equipment and can be used in power supply and high current filtering circuits.
