74479775222A Description

Short technical summary and product information.

The Würth Elektronik 74479775222A is a power multilayer inductor from the WE-PMI series, designed for surface mount applications in general electronic equipment. It comes in a compact 0805 (2012 Metric) package with dimensions 2.00 mm x 1.20 mm x 1.00 mm.

 

Electrically, this inductor provides 2.2 µH inductance with ±20% tolerance. It has a typical DC resistance of 200 mΩ and a maximum of 250 mΩ. The rated current is 700 mA for a 20 K temperature rise and 1000 mA for a 40 K rise. The saturation current is 700 mA typical. The self-resonant frequency is at least 50 MHz, and the minimum Q-factor is 23 at 1 MHz, 5 mA.

 

Environmental compliance includes RoHS (2011/65/EU), REACH conformity, and halogen-free status per JEDEC JS709B and IEC 61249-2-21. The moisture sensitivity level is MSL 1 (unlimited). The operating temperature range is -40°C to +125°C. The inductor is unshielded and uses multilayer construction.

 

The component is suitable for power management and DC-DC converter circuits where low DC resistance and high current handling are required in a small footprint.
