The Würth Elektronik 74437349010 (WE-LHMI series) is a shielded, molded SMD power inductor providing 1 µH inductance with ±20% tolerance. It is rated for a performance current of 13.4 A max (ΔT = 40 K, per IEC 62024-2-2020 Class C) and offers saturation currents of 13 A typ at 10% inductance drop and 25.8 A typ at 30% drop. DC resistance is 6.5 mΩ max (6.1 mΩ typ) and the self-resonant frequency is 51 MHz typ.
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 supports a maximum operating voltage of 120 V DC. The component is housed in a compact 7.3 mm x 6.6 mm x 3.0 mm surface-mount package with a nonstandard case. The molded, shielded construction uses an iron powder core, which helps reduce radiated EMI in power conversion circuits.
Applications include DC-DC converters, power supply filtering, and other power management circuits where high current handling and low DCR are required. The part is RoHS3 compliant, REACH conform, halogen free, and rated MSL 1 for unlimited floor life. It is compatible with standard SMD soldering processes.
