The Würth Elektronik 74438357047 is a shielded molded power inductor from the WE-MAPI series. It offers a nominal inductance of 4.7 µH with ±20% tolerance, measured at 100 kHz and 10 mA. The component is rated for a maximum DC current of 5.1 A (ΔT=40K) and features a typical saturation current of 4.15 A at 10% inductance drop and 8.2 A at 30% drop. DC resistance is 39.9 mΩ typical and 44 mΩ maximum at 20°C.
This inductor is designed for surface-mount assembly in a compact 1616 (4040 Metric) package measuring 4.10 mm x 4.10 mm with a maximum height of 3.10 mm. It is constructed with a metal composite core and is fully shielded to minimize electromagnetic interference. The component is qualified to AEC-Q200 Grade 1, making it suitable for automotive applications. It operates over a temperature range of -40°C to +125°C and supports a maximum operating voltage of 80 V DC.
