FAQ

Q: What are the advantages of flat wire winding compared to traditional round wire?

A: Flat wire has a larger surface area, offering higher current capacity, lower DCR, and better heat dissipation. In high-current applications, flat wire inductors effectively reduce power loss and skin effect loss, improving overall efficiency, especially suitable for high-current applications up to the 28A level.

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.

Q: What is the significance of excellent thermal stability?

A: Excellent thermal stability ensures the inductor maintains stable electrical performance across a wide temperature range, making it suitable for applications with large temperature variations such as automotive electronics and communication equipment, improving system reliability.

Q: How to apply for samples? What is the lead time?

A: You can submit a sample application through our website or email. Please provide your company information and target model. Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks.
