FAQ
Q: How does the composite structure reduce audible noise?
A: The composite structure uses special core materials and filling processes to effectively reduce vibration caused by the magnetostrictive effect. This significantly reduces audible noise in the audible frequency range, making it especially suitable for noise-sensitive portable devices and consumer electronics applications.
Q: What are the advantages of the lowest height design in its package size?
A: The lowest height design in its package size saves PCB vertical space, making it especially suitable for height-constrained compact device designs, meeting the trends of miniaturisation and slim form factors without compromising power handling capability.
Q: What does the lowest DCR/μH in its package size mean?
A: The lowest DCR/μH in its package size means this inductor offers the lowest DC resistance and power loss per microhenry in the same package size, ensuring high conversion efficiency and low heat generation. It is suitable for high-density power supply designs with strict efficiency and thermal management requirements.
Q: What are the advantages of the shielded structure?
A: The shielded structure uses a closed magnetic circuit design to confine magnetic flux inside the core. It effectively reduces leakage flux and electromagnetic interference to nearby sensitive circuits, improving system EMC performance.
