FAQ

Q: What are the advantages of the magnetic shield structure?

A: The magnetic shield 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. In high-density PCB layouts suchs as communication equipment and automotive electronics, shielded inductors significantly improve system EMC performance.

Q: What is the significance of excellent mechanical strength and high reliability?

A: Excellent mechanical strength ensures the inductor is less likely to be damaged during PCB assembly and transportation. High reliability design ensures long-term stable operation under various harsh conditions, reducing maintenance and replacement costs.

Q: How long is the delivery time and what packaging methods are used?

A: The standard lead time is 2-8 weeks after order confirmation, depending on product specifications and order quantity. Products are securely packed with cartons, foam, pallets, wrapping film, and fixing straps to ensure safe international transportation.
