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 such as communication equipment and automotive electronics, shielded inductors significantly improve system EMC performance.
Q: What are the inductance range and rated current of this series?
A: The inductance range covers 1μH to 100μH, with rated current up to 3.86A. The wide inductance range and high current capacity make it suitable for various applications from signal filtering to power conversion.
Q: How is rated current defined?
A: Rated current is defined as the DC current value at which inductance drops by 10% (IDC Max current is decreased 10% against its initial value). Test conditions are at 20°C ambient temperature. In actual applications, consider the effect of temperature rise on saturation current and allow sufficient design margin.
