Product Brief

V18014FS flat clip-on ferrite core is a split NiZn ferrite ring manufactured from VN09 grade material. Tailored specifically for flat ribbon cables, this component provides a minimum impedance of 20Ω at 25MHz and 55Ω at 100MHz to efficiently dampen high-frequency EMI noise. Its low-profile split construction enables simple attachment onto pre-assembled flat cables, with no wire stripping or cutting required. The item meets RoHS and REACH regulations, offering consistent noise attenuation to support end devices in satisfying EMC criteria.

Application Range

It is suitable for flat ribbon cables and flat signal lines used in consumer electronics, smart home hardware, industrial control panels, surveillance equipment and compact medical instruments. It works perfectly for internal wiring inside miniaturized electronic products where mounting space is restricted.

Purpose

Primarily designed to attenuate conducted and radiated high-frequency EMI noise on flat cables, minimize signal distortion triggered by electromagnetic interference, and facilitate finished products to successfully obtain EMC certification.

FAQ

Q1: Where should I place the snap-on ferrite core on the cable for optimal noise reduction? A: For best filtering performance, mount the ferrite core as close as possible to the device connector or noise source. Placing it near the equipment port maximizes suppression of outgoing interference.

Q2: Will stacking multiple snap-on ferrite cores improve the EMI suppression effect? A: Yes. Stacking two or more ferrite cores on the same cable can increase total impedance and enhance noise attenuation. But you still need to verify the effect based on your actual EMC test results.

Q3: What frequency range does NiZn snap-on ferrite core work best for? A: NiZn ferrite cores are optimized for high-frequency interference, typically ranging from several MHz up to hundreds of MHz. They are widely used to eliminate high-frequency cable EMI noise.

Q4: Does the number of turns of cable passing through the ferrite ring affect performance? A: Yes. Looping the cable through the ferrite core for extra turns will raise impedance and strengthen noise suppression. However, extra loops also increase cable capacitance and may impact signal integrity at very high frequencies.

Q5: What factors will weaken the noise suppression performance of ferrite cores? A: Improper size matching, physical cracks on the ferrite body, high operating temperature beyond the material limit, and incorrect installation position will all reduce the EMI filtering performance.
