Q1: What is the tolerance for the dimensions of V18004 ferrite core? A1: Each dimension has specified tolerance. The tolerance range is ±0.8mm to ±1.0mm as shown in our datasheet.

Q2: Is the ferrite magnetic ring fragile? A2: Ferrite material is ceramic-based. It is hard but brittle. Avoid strong impact or dropping to prevent breakage.

Q3: Does the permeability of ferrite core change with operating temperature? A3: Permeability will shift slightly with temperature. Keep working temperature below Curie temperature to keep stable performance.

Q4: Can you supply ferrite cores with pre-wound coils? A4: Yes, we can offer winding service for toroidal cores. Please send us your winding specification for quotation.

Q5: How do you pack the magnetic rings to avoid damage during shipment? A5: We use anti-static trays and carton packaging with cushion materials to protect ferrite cores from damage in transit.
