VIIP V18039 is a clamp on ferrite core manufactured from VN15 ferrite material with an initial permeability value of 1200. As a high permeability EMI noise absorber, it is engineered to remove electromagnetic interference from different types of cables. This component provides a minimum impedance of 125 Ohm at 25 MHz and 250 Ohm at 100 MHz. It maintains consistent magnetic properties, with Curie temperature above 160 degree Celsius and electrical resistivity greater than 106 Ohm meter. Every dimension is kept within plus or minus 1.0 mm tolerance. This magnetic ring adopts strict visual defect checking rules for damaged parts. It also satisfies RoHS and REACH regulations, assisting customers in EMC optimization and successful completion of certification assessments.

This clamp on ferrite core finds broad application in power supplies, battery chargers, battery packs, industrial control modules, communication hardware and diverse electronic cable assemblies. It can be mounted on power lines and signal wires for energy equipment, consumer electronics and industrial machinery. It is ideal for projects requiring high frequency noise reduction, electromagnetic radiation control and EMC performance upgrade prior to official certification testing.

V18039 magnetic ring is designed to absorb high frequency EMI noise generated on cables. It restrains both conducted and radiated electromagnetic disturbance, lowers cable noise level and enables hardware devices to satisfy EMC specifications. Thanks to its split style, users can fit it onto finished wiring harness quickly without taking cables apart. It addresses electromagnetic noise challenges of electronic goods and raises the pass rate of CE FCC UL certification.

Q: Can split ferrite cores work for both power cables and signal cables? A: Yes. Split ferrite cores can be applied to both power cables and signal cables. They suppress high frequency noise on both types of wires. The selection of ferrite grade depends on your noise frequency and target EMC requirement.

Q: What factors will affect the noise reduction effect of ferrite magnetic rings? A: Several key factors influence noise suppression performance. They include ferrite material grade, magnetic ring inner diameter matching, installation position, cable winding turns and the actual frequency band of interference signals.

Q: Can I install this split ferrite core on moving cables or flexible cables? A: Yes. The split ferrite core is suitable for flexible cables and moving cables. Please select proper installation position and protect the magnetic ring from strong mechanical impact or repeated heavy squeezing to avoid cracking.

Q: What will happen if the operating temperature exceeds the Curie temperature of ferrite core? A: Once temperature goes beyond Curie temperature, the ferrite material will lose its magnetic property temporarily. The noise absorption function will disappear. Magnetic performance can recover after temperature drops back to normal range.

Q: Can you provide samples of ferrite magnetic rings for our EMC pre test? A: Sure. We support sample supply for customers to carry out EMC pre test and performance verification. You can tell us your target model and application information, and we will arrange sample delivery accordingly.
