B82724J8672N040

Common Mode Chokes, or CMC, are devices used by electricians and electronic engineers for suppression or elimination of electrical noise.The B82724J8672N040 is one such device. It is a ferrite EMI filter designed to provide extremely effective common mode noise suppression. This device is especially suitable for high frequency applications such as power supplies, audio equipment and instrumentation where high rejection of common mode EMI noise is required.

Application Field

The B82724J8672N040 is an ideal choice for applications requiring high common mode noise suppression. The CMC filter offers robust design against voltage surges making it suited for machines or robotic machinery where frequent voltage spikes can be expected. This model of common-mode chole is also suitable for applications requiring low insertion loss. It\'s small form factor makes it suitable for tight fit on boards with little to no clearance.

Working Principle

The B82724J8672N040 is based on standard common-mode choke architecture and works by limiting the flow of current in both directions within a conductor. The resistance to current flow through the choke caused by the constricted passage, known as impedance, helps reduce the effects of unwanted interference. This is achieved through the use of two conductors with the magnetic field generated by one conductor influencing the current flow in the other.

The B82724J8672N040 is an example of a CMC filter incorporating ferrite material to further increase the filter performance. Ferrite material has the desirable property of having a high permeability, meaning that the inductance or impedance of the B82724J8672N040 will increase as the frequency increases, which is ideal for suppressing high frequency interference.

The B82724J8672N040 also features a built in capacitor, the maximum operational capacitance of which can range between 70pF and 150pF. The capacitor, in combination with the inductive elements, acts as a low pass filter to further reduce the effects of noise on the supply line.
