744774022 Description

Short technical summary and product information.

The Würth Elektronik 744774022 is a fixed SMD power inductor from the WE-PD2 series. It offers a nominal inductance of 2.2 µH with ±20% tolerance, measured at 10 kHz and 100 mV. The rated current is 4.6 A maximum under a temperature rise of 40 K, and the saturation current is 8.2 A typical. The DC resistance is 0.026 Ω typical and 0.041 Ω maximum at 20°C. The self resonant frequency is 54 MHz typical, and the maximum operating voltage is 120 V DC.

 

This inductor uses a drum core ferrite core with wirewound construction and is unshielded. It is designed for surface mount assembly in a nonstandard package measuring 5.80 mm x 5.20 mm x 4.85 mm. The operating temperature range is -40°C to 125°C, with ambient temperature up to 85°C for rated current. The component is RoHS compliant, REACH conform, and halogen free per JEDEC JS709B and IEC 61249-2-21. Moisture sensitivity level is 1.

 

Typical applications include power supply filtering, DC-DC converters, and energy storage in switching regulators. The unshielded design should be considered for EMI-sensitive circuits.
