The Würth Elektronik 74477004 is a surface mount shielded power inductor from the WE-PD series, featuring a drum core wirewound construction with ferrite core material. It offers an inductance of 4.7 µH with ±30% tolerance, measured at 100 kHz/250 mV. The component is rated for a maximum current of 9.5 A at a 40 K temperature rise (IEC 62024-2-2020), with a performance rated current of 11 A max. Saturation current is 11 A typical at 10% inductance drop and 14.3 A typical at 30% drop.
The DC resistance is 9 mΩ typical and 12 mΩ maximum at 20°C, with a self-resonant frequency of 31.2 MHz typical. The maximum operating voltage is 120 V DC. The inductor is designed for an operating temperature range of -40°C to +125°C, with ambient temperature limited to +85°C when referring to the rated current. Moisture Sensitivity Level is 1.
The package is a nonstandard surface mount with dimensions 12.00 mm x 12.00 mm x 8.00 mm max. The component is shielded to reduce electromagnetic interference. It is AEC-Q200 Grade 1 qualified for automotive applications, and conforms to RoHS (2011/65/EU&2015/863), REACH (EC)1907/2006, and Halogen Free (JEDEC JS709B) standards.
