FAQ
Q: Is the high temperature resistance of the magnetic ring suitable for automotive electronic environments?
A: Yes. The maximum operating temperature of the ferrite magnetic ring can reach 250℃, which can withstand high temperature environments such as the engine compartment of the car, and is resistant to vibration and corrosion, meeting the reliability requirements of automotive electronics.
Q: When purchasing in batches, how to ensure the consistency of the magnetic properties of the magnetic ring?
A: Regular manufacturers will ensure that the magnetic property deviation of the same batch of products is ≤±5% through sintering process control and magnetic property sorting before leaving the factory.
Q: Does it support customization of specifications with different inner diameters and outer diameters?
A: Support. The standard specifications cover inner diameters of 1mm to 100mm and outer diameters of 2mm to 150mm. Non-standard sizes can also be customized according to demand.
Q: What protections should be taken during transportation and storage?
A: Shockproof foam or carton packaging is required during transportation to prevent the magnetic ring from colliding and breaking; the storage environment must be dry, without strong magnetic field interference, away from corrosive gases, and can be stored for a long time at room temperature.
