UU-type filter inductor series

UU‑type inductors utilize a UU‑shaped magnetic core, with the windings wrapped directly around the core to form a dual‑coil structure. The core’s high permeability concentrates the magnetic flux, presenting high impedance to common‑mode noise currents and thereby attenuating high‑frequency interference signals, while exerting minimal impact on differential‑mode signals. These inductors are widely employed in switch‑mode power supplies, communication equipment, industrial control circuits, and other applications, meeting electromagnetic compatibility (EMC) standards.
