VIIP V18039 is a clip on ferrite core produced from VN15 ferrite material with initial permeability of 1200. It serves as a high permeability EMI noise absorber built to remove electromagnetic interference from cables of various types. The component achieves minimum impedance of 125 Ohm at 25 MHz and 250 Ohm at 100 MHz. It keeps stable magnetic characteristics, with Curie temperature over 160 degree Celsius and electrical resistivity higher than 106 Ohm meter. Every dimension is maintained within plus or minus 1.0 mm tolerance. This magnetic ring adopts rigorous visual screening rules for breakage defects. It meets RoHS and REACH specifications, assisting clients in EMC optimization and smooth completion of certification evaluations.

This clip on ferrite core is widely deployed in power supplies, battery chargers, battery systems, industrial control units, communication devices and diverse electronic cable assemblies. It can be fitted onto power lines and signal wires for energy equipment, consumer electronics and industrial machines. It is ideal for projects requiring high frequency noise reduction, electromagnetic radiation control and EMC performance improvement before formal certification tests.

V18039 magnetic ring is developed to absorb high frequency EMI noise carried on cables. It suppresses conducted and radiated electromagnetic disturbance, cuts cable noise and helps electronic hardware satisfy EMC requirements. The split construction enables quick installation on finished wiring harnesses with no cable disconnection required. It handles electromagnetic noise challenges of electronic products and lifts the pass rate of CE FCC UL certification.|

Q: Can ferrite magnetic rings completely eliminate all electromagnetic noise on cables? A: Ferrite magnetic rings can greatly attenuate high frequency noise but cannot remove all interference entirely. For severe EMI issues, combining magnetic rings with EMI filters or shielding solutions will achieve better EMC results.

Q: Can I install multiple cables inside one split ferrite core together? A: It is not recommended to put several cables inside a single ferrite core. Mixed cables may cause interference offset and reduce the noise suppression effect. One ferrite core is better used for one single cable.

Q: What may cause ferrite magnetic rings to crack during application? A: Common causes include strong mechanical impact, excessive squeezing, sharp collision or improper installation force. Once cracked, the magnetic path is broken and the EMI noise suppression capability will drop significantly.

Q: Is special tool required for installing split ferrite cores? A: No special tools are needed. The split design allows manual opening and clamping onto cables. Just open the shell gently and fasten it around the cable for simple and fast installation.

Q: Can ferrite cores work well in outdoor exposed equipment? A: The ferrite material itself works outdoors, but you need to protect the magnetic ring shell from direct ultraviolet radiation and heavy rain. Proper housing protection can guarantee long term stable EMC performance in outdoor environments.
