744774147 Description

Short technical summary and product information.

The Würth Elektronik 744774147 is a fixed inductor from the WE-PD2 series, offering 47 µH inductance with ±15% tolerance. It is rated for 860 mA continuous current (ΔT = 40 K) and can handle a saturation current of 1 A (ΔL/L < 10%). The DC resistance is 260 mΩ typical, 370 mΩ maximum at 20°C. The self-resonant frequency is 11.5 MHz typical. This unshielded inductor uses a drum core with ferrite material and a wirewound winding. It is housed in a nonstandard surface mount package measuring 5.8 mm x 5.2 mm x 4.85 mm. The operating temperature range is -40°C to +125°C, with an ambient temperature range of -40°C to +85°C for rated current. Storage conditions are below 40°C and 75% RH. The component is RoHS, REACH, and Halogen Free compliant, with an MSL of 1 (unlimited). It is suitable for power supply filtering, DC-DC converter output filtering, and other low-profile power applications.
