Customized Power Inductor

  • June 28. 2022

The power inductor is an inductor with a large current passing through it, comparing traditional inductor, it’s with small size, high Q value, low impedance, high efficiency, low temperature rise, customized.

When design the power inductors, engineer pay attention to optimizing the click structure, to guarantee the internal magnetic field of products becomes more uniform, and the power inductors winding wires must meet requirements. The power inductors are popular used in DC-DC (power module) loops to adjust power output, stabilize current and store energy, such as switching power supplies, green energy vehicle charging piles.
