Key Advantages for Automotive Electronics
EMI/RFI Shielding Superiority
Mu-metal grade permeability (μ ≥ 20,000) blocks 98% of electromagnetic noise up to 10 GHz, safeguarding LiDAR and infotainment systems.
Micro-Formability
Ultra-fine grain structure (ASTM 12–14) enables precision etching for <0.05mm connector pins and micro-relay components.
Thermal Cycling Endurance
CTE (Coefficient of Thermal Expansion) matched to FR-4 substrates (11.5 ppm/°C), preventing solder joint fatigue in ECU modules.
High-Speed Stamping Compatibility
Anti-adhesive coating reduces tool wear by 40% in progressive die systems for mass-producing fuse boxes and relay contacts.
Sustainable E-Mobility Alignment
Carbon-neutral production process with 95% recycled scrap utilization, supporting OEM ESG targets.

Technical FAQs
Q: How does your material compare to ferrite cores in EV charging modules?
A: Our iron coils achieve 30% higher saturation flux density (2.15T vs. 0.5T for Mn-Zn ferrite), enabling compact 800V OBC designs with 95% efficiency at 50kHz.
Q: Can you supply pre-insulated coils for motor stator stacking?
A: Yes! Laser-applied ceramic coatings (Al₂O₃ or SiO₂, 10–50μm) provide 3kV dielectric strength for hairpin winding applications.
Q: Do your coils meet creepage/clearance requirements for 48V systems?
A: Absolutely. Edge-radius control (<5μm) and customized coatings ensure compliance with ISO 6469-3 electrical safety standards.
