VIIP Factory V18017FS Grey Toroidal Ferrite Core 18.9mm OD Anti‑Interference Ferrite Ring. Designed for power filter and common‑mode choke winding, the VIIP V18017FS toroidal ferrite core provides effective EMI and RFI noise suppression for high‑frequency circuits.

The VIIP V18017FS grey toroidal ferrite core adopts high‑performance nickel‑zinc soft ferrite material with 52.6 mm outer diameter and 15.5 mm thickness. It delivers minimum impedance of 50Ω@25MHz and 110Ω@100MHz for EMI & RFI noise suppression across the 1‑500 MHz frequency range. This wound‑type toroidal core is widely used for winding common‑mode chokes and EMI filter inductors. RoHS and REACH compliant, it serves IT‑AV equipment, industrial control and consumer‑electronic EMC debugging. Free samples are available for evaluation.

Manufactured by VIIP with premium grade nickel‑zinc ferrite material featuring initial permeability of 1600, the V18017FS grey toroidal ferrite core effectively suppresses high‑frequency EMI and RFI noise. It helps finished inductors and filters achieve stable filtering performance and assists equipment to pass EMC compliance tests. High saturation magnetic flux density of 360MT avoids magnetic saturation‑caused performance drop under complex working conditions.
