FAQ
Q: How to choose between ceramic core and ferrite core?
A: Ceramic cores offer higher Q factor and better high-frequency characteristics, suitable for RF and microwave bands. Ferrite cores have higher magnetic permeability, allowing larger inductance values in the same volume, suitable for lower frequency applications or applications requiring higher inductance values. Ceramic is the standard configuration, while ferrite is an optional choice.
Q: What are the benefits of high Q factor for circuit design?
A: High Q factor means lower energy loss and better frequency selectivity at specific frequencies. It improves resonant circuit gain and selectivity, reduces insertion loss, improves filter out-of-band rejection, and enhances oscillator frequency stability.
Q: What package sizes are available for this series?
A: Six standard sizes are available: 0402, 0603, 0805, 1008, 1210, and 1812. They can be flexibly selected based on PCB space and inductance requirements.
Q: What are the advantages of wire-wound structure compared to multi-layer structure?
A: Wire-wound structure offers higher Q factor and higher current capacity at high frequencies, especially suitable for high-frequency applications requiring high Q factor and high current, such as RF front-ends and power amplifiers.
