The Würth Elektronik 74437349022 is a WE-LHMI series SMT power inductor designed for high current applications. It features a shielded molded construction with an iron powder core, providing low magnetic radiation and stable performance. The inductor offers an inductance of 2.2 µH with ±20% tolerance, measured at 100 kHz and 10 mA.
Electrical characteristics include a typical DC resistance of 11.2 mΩ and a maximum of 12 mΩ at 20 °C. The rated current is 9.9 A maximum based on a 40 K temperature rise, with typical saturation currents of 10.5 A at 10% inductance drop and 19.1 A at 30% drop. The self-resonant frequency is 30 MHz typical, and the maximum operating voltage is 120 V DC.
The inductor is housed in a 7050 surface-mount package with dimensions of 7.30 mm length, 6.60 mm width, and 3.0 mm height. It operates over an ambient temperature range of -40 °C to +85 °C and an operating temperature range of -40 °C to +125 °C. The component is RoHS, REACH, and halogen-free compliant with MSL level 1.
