Product Brief

V18014FS flat clip-on ferrite core is a separable NiZn ferrite ring manufactured with VN09 material. This product is specially designed for flat ribbon cables. It reaches minimum impedance of 20Ω at 25MHz and 55Ω at 100MHz to effectively damp high-frequency EMI noise. Its thin split structure can be fastened directly onto pre-connected flat cables without cutting the wire. This item complies with RoHS and REACH standards, delivering reliable noise attenuation and helping end electronic devices satisfy EMC compliance specifications.

Application Range

It is applicable to flat ribbon cables and flat signal wires of consumer electronics, smart home devices, industrial control panels, surveillance systems and miniature medical instruments. It is ideal for internal wiring in compact electronic devices with limited mounting space.

Purpose

It mainly restrains conducted and radiated high-frequency EMI noise on flat cables, reduces signal distortion triggered by electromagnetic interference, and enables finished products to pass EMC certification assessments smoothly.

FAQ

Q1: What is the core working principle of snap-on ferrite cores for noise suppression?
A: Ferrite material presents high impedance at high frequencies. It converts unwanted high-frequency electromagnetic noise into heat and dissipates it, while leaving normal working signals unaffected.

Q2: Can the same flat snap-on ferrite core be reused after removal from cables?
A: Yes, provided the ferrite ring is intact without cracks. The clip-on structure can be opened and re-clamped multiple times for repeated installation.

Q3: How to test the actual noise suppression effect of ferrite cores?
A: You can perform EMC pre-compliance testing with spectrum analyzers. Compare the noise level before and after installing the ferrite core to evaluate its filtering performance.

Q4: Does ambient humidity affect the magnetic performance of ferrite cores?
A: Normal indoor humidity has little impact. Long-term exposure to high humidity may cause surface corrosion of plastic clips, so dry storage conditions are recommended.

Q5: What should I do if the ferrite clip cannot stay firmly fastened on the flat cable?

A: Confirm you have selected the correct size matching your flat cable thickness. You may also use cable ties for auxiliary fixation to guarantee stable installation.
