The Würth Elektronik 74437324033 is a shielded, molded SMD power inductor from the WE-LHMI series. It offers a nominal inductance of 3.3 µH with a ±20% tolerance, measured at 100 kHz and 10 mA. The component is designed for high-performance power applications, with a rated current of 3.5 A (ΔT = 40 K per IEC 62024-2-2020 Class C) and typical saturation currents of 2.75 A at 10% inductance drop and 5.45 A at 30% drop.
This inductor uses an iron powder core material and features a shielded construction to minimize electromagnetic interference. The DC resistance is typically 69 mΩ with a maximum of 76 mΩ at 20 °C. It has a self-resonant frequency of 40 MHz and a maximum DC operating voltage of 120 V. The component is rated for an ambient temperature range of -40 °C to +85 °C and an operating temperature range of -40 °C to +125 °C.
The 74437324033 is housed in a nonstandard SMD package with dimensions of 4.45 mm x 4.06 mm x 2.00 mm. It is RoHS, REACH, and Halogen Free compliant, and has a Moisture Sensitivity Level (MSL) of 1 (unlimited).
