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.
