Inductors are energy storage and filtering components in power electronic circuits, classified into three types based on materials: iron silicon aluminum, iron nickel molybdenum, and metal composite magnetic powder cores. The power inductor adopts a distributed air gap design, with a saturation current density of 500A/cm ² and a loss of<100mW/g @ 100kHz. The RF inductor adopts low-temperature co fired ceramic (LTCC) technology, with a Q value greater than 60@2.4GHz The key parameters include sensitivity tolerance ± 5%, self resonant frequency (SRF), and direct current resistance (DCR). EMI suppression inductor adopts common mode structure, with differential mode insertion loss> 40dB@30MHz In SiC/GaN device applications, it is necessary to match ultra-low parasitic capacitance (<5pF) and dv/dt tolerance>100V/ns. Surface mount inductors that comply with AEC-Q200 automotive standards have achieved full-size coverage from 0201 to 1260.
