VIIP V18039 is a split ferrite core made of VN15 ferrite material with initial permeability of 1200. It is a high permeability EMI noise absorber designed for cable electromagnetic interference elimination. The component delivers minimum impedance of 125 Ohm at 25 MHz and 250 Ohm at 100 MHz. It features stable magnetic performance with Curie temperature higher than 160 degree Celsius and electrical resistivity over 106 Ohm meter. All dimensions are controlled within tolerance plus or minus 1.0 mm. This magnetic ring follows strict appearance breakage inspection standards and meets RoHS and REACH requirements, supporting customers to complete EMC optimization and pass related certification tests.

This split ferrite core is widely used in power supplies, chargers, battery systems, industrial control units, communication equipment and various electronic cable assemblies. It can be installed on power cables and signal cables of energy equipment, consumer electronics and industrial devices. It works well for projects that need to suppress high frequency noise, reduce electromagnetic radiation and improve EMC performance before formal certification.

The main purpose of V18039 magnetic ring is to absorb high frequency EMI noise on cables. It suppresses conducted and radiated electromagnetic interference, cuts cable noise and helps hardware products meet EMC standards. Its split design allows fast installation on finished wiring harness without wire disassembly, solving electromagnetic noise problems for electronic products and improving the success rate of CE FCC UL certification.

Q: What is the core function of split ferrite magnetic ring? A: The split ferrite magnetic ring acts as an EMI noise absorber. It suppresses high frequency electromagnetic interference on power cables and signal cables, reduces conducted and radiated noise, and helps your equipment meet EMC requirements to pass CE FCC and other certification tests.

Q: How do I select the proper ferrite magnetic ring model for my cable? A: You need to confirm the outer diameter of your cable to match the inner dimension of magnetic ring. Besides, select suitable ferrite material based on your noise frequency range. Our team can provide professional EMC suggestions and recommend proper split ferrite core models according to your application and test data.

Q: What is the difference between NiZn ferrite and MnZn ferrite magnetic ring? A: NiZn ferrite magnetic rings perform better on high frequency noise suppression with high resistivity and stable EMC performance above 1 megahertz. MnZn ferrite cores are more suitable for low frequency interference. Most cable EMI elimination projects choose NiZn ferrite split magnetic rings.

Q: Do your ferrite magnetic rings comply with RoHS and REACH standards? A: Yes. All our split ferrite cores and magnetic rings comply with RoHS and REACH standards. We can provide relevant certification documents for your product inspection and overseas market customs clearance.

Q: Does the magnetic ring need multiple cable turns to achieve better noise suppression? A: Winding the cable through the magnetic ring for multiple turns will increase impedance and improve noise suppression. However single turn installation is enough for most cases. Our engineers can advise on the best winding method according to your EMC test result and interference condition.
