Notes: Product size and inductance can be customized
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, it significantly improves signal integrity and system electromagnetic compatibility.
Q: What package sizes are available for this series?
A: Five standard sizes are available: 0402, 0603, 0805, 1206, and 1210. They can be flexibly selected based on PCB space and inductance requirements, covering applications from ultra-small to general-purpose.
Q: Is this product suitable for reflow soldering?
A: Yes. This product is suitable for reflow soldering with excellent solderability, making it suitable for automated SMT production lines and high-density mounting.
Q: How to apply for samples? What is the lead time?
