5. FAQ

Q1: Can you customize special sizes and shapes of magnetic cores? A6: Yes. We support full customization including outer diameter, inner diameter, height, surface coating and special tolerance requirements according to customers’ filter design and equipment parameters.

Q2: What is the difference between amorphous core and ferrite core in EMC performance? A7: Amorphous cores have higher saturation flux density, wider temperature adaptability and better low-medium frequency noise suppression. Ferrite cores are more suitable for high-frequency EMI interference with lower cost and lighter weight.

Q3: How to choose the correct magnetic core size for my filter design? A8: You need to confirm working current, interference frequency range, operating temperature and winding turns. Larger cores provide higher saturation resistance, while smaller cores are more suitable for compact equipment design.

Q4: Will winding turns affect the final filtering effect? A9: Yes. More turns increase low-frequency impedance and improve noise suppression, but too many turns will raise distributed capacitance and weaken high-frequency performance. Reasonable turns matching is essential for optimal EMC results.

Q5: Do your magnetic cores have consistent batch-to-batch quality? A10: All cores are produced under standardized heat treatment and precision processing procedures. We strictly control dimensional tolerance and magnetic performance deviation to ensure zero difference in mass production batches.
