Common questions about magnetic component selection, certifications, and customization

View All FAQs →

How do FeNi powder cores compare to ferrite cores?

FeNi (50%Fe-50%Ni) powder cores vs ferrite: ① Higher Bs≥1.5T (ferrite 0.3-0.5T) for high current applications; ② Wide temp range -40°C to +180°C; ③ 30% volume reduction; ④ Gapless design for better EMI. Ferrite remains cost-effective for >500kHz applications.

Do you offer custom magnetic components? What is MOQ?

Yes, we offer OEM/ODM customization including custom size, material, inductance, and packaging. Standard MOQ is 10,000 pcs per model; sample orders negotiable. Engineering team responds within 24 hours with free technical evaluation.

What certifications do you hold?

We hold IATF 16949 (Automotive Quality Management), AEC-Q200 (Passive Component Qualification), ISO 9001 (QMS), ISO 14001 (Environmental Management), and RoHS/REACH compliance. All certificates available upon request.

What is the lead time for standard products?

Standard models (YTFN-6028, YTFN-8040) stocked with 2-4 week lead time. Custom designs 6-8 weeks. For large-volume orders, please confirm capacity in advance. 24/7 FAE support available.

Are your cores suitable for EV charger applications?

Yes. Our FeNi cores are widely used in DC fast chargers and OBCs. AEC-Q200 qualified products support 800V platforms at 20kHz-100kHz with μ variation ≤8% (-40°C to +180°C). Contact us for the EV application design guide.

Do you ship worldwide? What are your export terms?
