7447730 Description

Short technical summary and product information.

The 7447730 is a surface mount power inductor from Würth Elektronik, part of the WE-PD2 series. It features an inductance of 1 µH with ±20% tolerance, measured at 10 kHz and 100 mV. The component is rated for a continuous current of 4 A (ΔT = 40 K) and has a typical saturation current of 5.72 A. DC resistance is 0.014 Ω typical and 0.049 Ω maximum. The self-resonant frequency is typically 110 MHz, and the maximum operating voltage is 120 V. The inductor uses a ferrite core and is unshielded. It is housed in a 4532 package (4.5 mm x 3.2 mm x 4.0 mm) suitable for surface mount assembly. Operating temperature range is -40°C to 125°C, with ambient temperature for rated current from -40°C to 85°C. The component is RoHS3, REACH, and Halogen Free compliant with MSL 1. Designed for general electronic equipment, it is suitable for power supply circuits, DC-DC converters, and filtering applications.
