5. FAQ
Q1: Are your magnetic cores RoHS and REACH compliant? A1: All our magnetic cores strictly comply with RoHS and REACH environmental standards. We can provide official test reports and certification documents to support customers’ product certification and customs clearance.
Q2: What causes magnetic core saturation in actual operation? A2: Core saturation is mainly caused by excessive working current, strong DC bias, improper core size selection, and long-term overload operation. Saturation will sharply reduce permeability and weaken EMI filtering performance.
Q3: Can magnetic cores be used for both AC and DC power filters? A3: Yes. Different core materials are designed for different application scenarios. Amorphous cores are ideal for AC power line noise suppression, while ferrite and powder cores perform well in DC-DC filtering and high-frequency circuit noise reduction.
Q4: What is the shelf life of unused magnetic cores? A4: If stored in dry, room temperature and non-corrosive environment, magnetic cores have a shelf life of more than 5 years. Proper storage prevents oxidation, moisture absorption and magnetic performance attenuation.
Q5: Why does the filter produce buzzing noise after winding the magnetic core? A5: The noise is mainly caused by magnetostriction and loose winding turns. Uneven winding, insufficient insulation distance and unstable current load will also cause vibration and acoustic noise during operation.
