Q1: What is the main function of V18004 ferrite magnetic ring? A1: It is mainly used for EMI suppression, filtering high frequency noise and making power inductors & common mode chokes.

Q2: What is the material grade of V18004 toroidal ferrite core? A2: Material is VN09 soft ferrite, initial permeability is 850 ±20%.

Q3: Are your ferrite magnetic rings ROHS and REACH compliant? A3: Yes, all our magnetic cores meet ROHS and REACH standards, suitable for export electronic products.

Q4: What will cause ferrite core saturation? A4: Excessive current will lead to magnetic saturation. Once saturated, inductance will drop and noise suppression performance will fail.

Q5: Can I get free samples of V18004 toroidal ferrite core? A5: Yes, we can provide V18004 samples for performance testing, customers only need to bear the freight cost.
