The Würth Elektronik 74437349033 is a WE-LHMI series shielded molded power inductor designed for high current power applications. It offers an inductance of 3.3 µH with ±20% tolerance, measured at 100 kHz/10 mA. The rated current is 7.5 A maximum (ΔT=40 K), with saturation currents of 7.9 A typical at 10% inductance drop and 15.1 A typical at 30% drop. DC resistance is 20.9 mΩ maximum and 19 mΩ typical at 20°C. The self-resonant frequency is 26 MHz typical, and the maximum operating voltage is 120 V DC.
The inductor features an iron powder core and is fully shielded to minimize electromagnetic interference. It is housed in a surface mount package with dimensions 7.30 mm x 6.60 mm x 5.00 mm (nonstandard case). Operating temperature range is -40°C to 125°C, with ambient temperature range -40°C to 85°C. The component is RoHS, REACH, and Halogen Free compliant, with MSL 1 (unlimited floor life).
This inductor is suitable for power management circuits including DC-DC converters, voltage regulator modules, and power supply filtering. Its low DCR and high current handling make it ideal for applications requiring efficient power delivery in compact designs.
