Frequently Asked Questions
Expert answers to common engineering queries regarding soft ferrite materials.
Mn-Zn (Manganese-Zinc) ferrites are generally used for lower frequency applications (typically under 1 MHz) where high initial permeability and high saturation flux density are strictly required, such as in SMPS transformers and broadband communications. Conversely, Ni-Zn (Nickel-Zinc) ferrites exhibit much higher electrical resistivity, making them the optimal choice for high-frequency interference suppression and RF applications up to hundreds of MHz.
Selection heavily depends on your target operating frequency and temperature. For frequencies between 100kHz and 500kHz, our 6H40 or 6H45 materials offer excellent balance between high saturation and low core loss. If your design pushes above 500kHz up to 1MHz+, specialized materials like 7H series are necessary to mitigate rapid temperature increases caused by high-frequency power losses.
Yes, absolutely. As an ISO 9001 certified OEM/ODM manufacturer under the SINOSTEEL group, we support massive custom engineering. We can modify standard EE, ER, or PQ geometries, grind precision air gaps (AL value matching), or tool entirely new custom shapes directly derived from your CAD drawings. Please consult with our engineers for minimum order quantities (MOQ) and tooling lead times.
