The Würth Elektronik 74437346015 is a surface-mount power inductor from the WE-LHMI series. It features an iron powder core and shielded construction for low electromagnetic interference. Key electrical specifications include an inductance of 1.5 µH ±20% measured at 100 kHz/10 mA, a typical self-resonant frequency of 45 MHz, and a maximum DC resistance of 15 mΩ (13 mΩ typical).
Current ratings: The component is rated for a performance rated current (IRP,40K) of 9.1 A maximum, based on a 40 K temperature rise per IEC 62024-2-2020. Saturation current is 11.2 A typical at 10% inductance drop and 27.6 A typical at 30% drop. Operating voltage is 120 V DC maximum.
Environmental and compliance: The inductor operates over an ambient temperature range of -40°C to +85°C and an operating temperature range of -40°C to +125°C. It is RoHS, REACH, and halogen-free compliant, with MSL 1 (unlimited). The package is a nonstandard SMD form factor measuring 7.30mm x 6.60mm x 3.10mm.
Applications: Suitable for power supply circuits, DC-DC converters, and energy storage applications where low DCR and high current handling are required. The shielded design reduces radiated noise.
