Five FAQ

FAQ 1
Question What is the difference between saturation flux density and remanence
Answer Saturation flux density reflects the maximum magnetic load capacity of material. Remanence represents residual magnetism after external magnetic field disappears. Both parameters are critical reference for high current working scenarios.
FAQ 2
Question Are ferrite magnetic rings environmentally friendly for export
Answer Our ferrite magnetic raw materials comply with common international environmental standards. They can meet basic requirement for most export projects. You can inform us of your target certification requirement and we will give corresponding suggestion.
FAQ 3
Question Can I use one magnetic ring for multiple different frequency noise
Answer A single magnetic ring can suppress interference within its effective frequency range. If your noise covers very wide frequency band you may need to combine multiple magnetic cores of different material grades to achieve ideal filtering result.
FAQ 4
Question What is relative loss factor of ferrite material
Answer Relative loss factor reflects energy loss level of magnetic material under specific frequency. Lower loss factor means less heat generation during operation. It is a vital index for equipment running continuously for long hours.
FAQ 5
Question How does working temperature affect magnetic ring performance
Answer Moderate temperature fluctuation brings limited influence. Continuous high temperature will increase magnetic loss and change permeability. Severe overheating may cause irreversible performance decline of ferrite core.
