Ferrite beads

Ferrite beads are passive components used to filter high-frequency electromagnetic and radio-frequency interference (EMI/RFI). They absorb and dissipate high-frequency energy as heat, reducing noise in circuits. Commonly used in power supplies, communication systems, consumer electronics (like smartphones and laptops), automotive electronics, and cables, they help maintain signal integrity and prevent interference. Ferrite Beads comply with standards such as IEC 61000-4-6 for EMI immunity, RoHS for hazardous substance restrictions, MIL-STD-220 for military reliability, and UL for electrical safety. Well-known manufacturers like TE Connectivity, Bel Fuse and other leading manufacturers offer their 3D CAD models on 3Dfindit, including Ferrite beads.
