Cylindrical Ferrites

Cylindrical ferrites are extremely important components in today’s electronics, essential for effective management of electromagnetic interference. Micros offers a wide range of cylindrical ferrites that will help you effectively suppress unwanted noise and ensure stable operation of your devices.

What are cylindrical ferrites and what are they used for?

Cylindrical ferrites are inductive components designed primarily to reduce:

  • electromagnetic interference (EMI),
  • radio frequency interference (RFI).

Cylindrical ferrites reduce interference in electronic circuits and cables by acting as filters that absorb high-frequency noise and convert it into heat. The cylindrical shape and easy installation on cables make them a very practical solution for many applications. It is no coincidence that they are widely used in:

  • computers,
  • audio-video equipment,
  • network devices.

Cylindrical ferrites can be found wherever signal integrity and EMC compliance are required.

How do cylindrical ferrites work?

The operation of cylindrical ferrites is based on their magnetic properties. When placed on a cable, they increase its impedance to high frequencies, creating resistance to interference currents. As a result, instead of spreading through the cable and emitting interference, unwanted signals are effectively suppressed.

Cylindrical ferrites are particularly effective in the frequency range from a few to several hundred MHz, making them ideal for eliminating noise generated by fast digital circuits and switching power supplies. Their material – usually based on iron oxides with nickel, zinc or manganese – is specifically selected for effective suppression in a given frequency band.

What to consider when choosing the right cylindrical ferrite?

When selecting a cylindrical ferrite, several key factors must be taken into account to ensure optimal noise suppression. Important aspects include:

  • size and inner diameter – both must match the cable on which the ferrite is to be mounted;
  • impedance characteristics – should be selected based on the frequency range;
  • ferrite material type – which determines the effective suppression range.

Micros offers cylindrical ferrites with a wide range of parameters, allowing you to find the perfect solution for your project and specific application requirements.
