How to Select a Ferrite Bead Inductor?

Selecting the right ferrite bead mainly depends on impedance, operating frequency, rated current, DC resistance, and mounting type.

1. Check the Impedance

Select an impedance suitable for the frequency of the unwanted noise. SHINHOM specifications provide impedance values at different frequencies for selected series.

2. Check the Rated Current

For power-line applications, choose a ferrite bead that can handle the required operating current without excessive temperature rise.

3. Check the DC Resistance

Low DC resistance helps reduce voltage drop and power loss, especially in high-current applications.

4. Select the Mounting Type

Through-Hole Ferrite Beads: suitable for leaded installation and applications requiring mechanical strength.

SMD Ferrite Beads: suitable for compact PCB layouts and automated assembly.

High-Impedance Ferrite Beads: suitable for stronger high-frequency noise suppression.

5. Match the Application

Consider the power or signal line, operating frequency, current, available space, and EMI requirements. For custom applications, the required electrical and mechanical specifications should be confirmed before selection.
