Ferrite core size table can help to choose the right size of ferrite cores for your engineering purposes. But before coming up to this, let's see what is there to know about ferrite cores.

Ferrite cores are ceramic materials that can be produced in a variety of shapes and sizes to meet your engineering requirements. To produce these ferrites, alloys are selected and mixed depending on the required permeability of the cores. Then the combination is molded to produce ferrites in their desired shapes and sizes with a pressure of 15- 200 tons per square inch. Ferrites are very effective in preventing unwanted noise signals that are between 2 MHz to 250 MHz range. They are also ideal for use in transformers, inductors, house appliances, etc, so their use is growing rapidly. But how do you find the right size of ferrite cores for your needs? Checking the Ferrite core size table is the answer. 

In this blog, we are going to share some important information about ferrite cores and how you can use the Ferrite Core Size Table to find the ideal cores for your needs. 

What are Ferrite Cores?

Ferrite Cores are MnZn based magnetic materials that are used in a range of electronic devices. They are hard and brittle in nature. The cores are available in dark grey and black colors. They are used in equipment to suppress unwanted high frequency noise levels. For this, ferrites concentrate the magnetic field, increase inductance and reactance and therefore, filter out the noise. With twin benefits of high magnetic permeability and high electrical resistivity, they are generally preferred over other materials. 

First, the ferrite concentrates the magnetic field, increasing inductance and therefore reactance, which impedes or 'filters out' the noise.

How Ferrite Cores are formed?

Ferrite cores go through several processes to be formed into a particular shape and size. Generally, they are formed using a combination of Manganese and Zinc (MnZn) ferrites. These compounds have high magnetic properties which are below the Curie Temperature. The cores can be magnetized easily as they have a higher intrinsic resistivity. You can use these cores up to high frequencies without lamination which is normally required for magnetic metals. After producing these ferrite components, they are collapsed to remove burrs and sharp edges so that they remain safe to use.
