Q: What are the advantages of the multi-layer ceramic structure compared to wire-wound structures?
A: The multi-layer ceramic structure uses laminated printing and co-firing processes. It offers small size, high consistency, and low parasitic parameters, making it suitable for high-frequency applications. Compared to wire-wound structures, multi-layer ceramic inductors provide higher Q factor and higher self-resonant frequency at high frequencies, with no core saturation issues. They are especially suitable for RF and microwave circuits.
Q: What are the advantages of the closed magnetic circuit design?
A: The closed magnetic circuit confines magnetic flux inside the core. It effectively reduces leakage flux and electromagnetic interference to surrounding circuits, while preventing magnetic coupling crosstalk between adjacent components. In high-density PCB layouts, the closed magnetic circuit design significantly improves signal integrity and system electromagnetic compatibility.
