Frequently Asked Questions
How does a ferrite work?
A ferrite adds impedance to unwanted high-frequency current on the conductor or cable passing through it. Part of that energy is dissipated as heat in the ferrite.
The impedance depends on the material, frequency and number of cable passes. Use the datasheet to select a starting point, then check the result on your equipment.
Do I need to buy the ferrite key separately?
No
Every one of our ferrites come with a ferrite safety key included as standard.
Is this ferrite available in a different colour?
Some ferrites are available in grey or black housings. Contact us with the part number if you need another colour, and we can confirm the available options.
Is this ferrite reusable?
Yes
The ferrite can be removed using the ferrite key supplied.
How many turns of wire should be used with this ferrite?
Start with the arrangement shown in the datasheet. Additional cable passes can increase impedance, but the effect varies with frequency and installation. Check the available aperture and cable bend radius, and compare results in your setup.
What happens to the ferrite if the operating temperature is exceeded?
Use the complete component within its specified operating-temperature range. The limit can depend on the magnetic material, housing and other construction details. Exceeding it can affect performance or damage the part.
