MECCANIXITY 20Pcs Toroid Ferrite Core, 17.5mm OD x 9.5mm ID x 35mm H Ferrite Ring Chokes Strong Round Toroidal to Reduce Signal Loss for RFI EMI RF HF Wires Suppression, Black

What is this?Ferrite cores are used to achieve pure signal integrity and reduce data loss in environments with high-frequency noise problems. Applications include audio, video, speaker cables, USB, Ethernet, computer peripheral cables, radios, RF transmitters, and DIY electronics.What will I get?Type: Toroid Ferrite CoreMaterial: ToroidOverall Size: 0.69 x 0.37 x 1.37 inches/17.5 x 9.5 x 35mm (OD x ID x H)Package Includes: 20 pcs Toroidal Transformer CoreAre there any advantages of the product?These toroidal cores are made of premium, high-permeability ferrite materials, exhibiting excellent chemical stability, thermal stability, insulation, and corrosion resistance. They also provide excellent EMI/RFI absorption.How to use it?Simply insert the toroidal transformer ring into the cable or pass the wire through the center hole to use it. It is designed to attenuate common-mode noise in the radio frequency (RF), electromagnetic interference (EMI), and high frequency (HF) ranges, reducing noise and improving signal clarity.What should I notice?For best results, the toroid cable or wire should be passed through the toroidal core multiple times to increase inductance and damping effect.
