Magnetic Bead Selection Techniques in PCB Circuit Design

In PCB board design, the choice between SMD magnetic beads and SMD inductors depends primarily on the application: chip inductors are crucial in resonant circuits, while chip beads excel in mitigating unwanted EMI noise. The unit of magnetic beads is ohms, representing impedance at specific frequencies, critical for their effective use in absorption filters and EMI control across various electronic applications.
