744773147

The 744773147 is a surface mount power inductor from Würth Elektronik's WE-PD2 series. It offers an inductance of 47 µH with ±10% tolerance, suitable for a variety of power management applications. The inductor is rated for a maximum current of 0.68 A at a 40 K temperature rise, with a saturation current of 0.77 A typical. DC resistance is 0.523 Ω typical and 0.844 Ω maximum at 20°C. The self-resonant frequency is 17 MHz, and the maximum operating voltage is 120 V.

This unshielded inductor uses a ferrite core with a drum core, wirewound construction. It is housed in a nonstandard 4532 package measuring 4.5 mm x 4.0 mm x 3.5 mm, suitable for surface mount assembly. 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 require temperatures below 40°C and humidity below 75% RH.

The component is compliant with RoHS (2011/65/EU & 2015/863), REACH (EC)1907/2006, and halogen-free standards (JEDEC JS709B and IEC 61249-2-21). Moisture sensitivity level is MSL 1, indicating unlimited floor life. Typical applications include DC-DC converters, power supply filtering, and low-profile power management circuits.
