Common Mode Chokes play a big role in today’s electrical world. They are used for filtering out any noise that is generated as a result of current passing through a wire, to provide immunity from Electro Magnetic Interference (EMI). One of the key components of a Common Mode Choke, is the PA2670NL.

The PA2670NL is a high frequency EMI filter produced by TDK Corporation and widely used in automotive, telecom, industrial and medical electronics, amongst many other applications. It is typically placed close to the power source to ensure that unwanted noise coming from the power source does not interfere with any other circuits. It does this by blocking the radiated EMI energy that passes along a wire.

The PA2670NL works on the principles of mutual inductance, where two coils are placed close to each other, with the same number of turns on both coils but in opposite direction. This helps to ‘cancel out’ the electric field generated and any electric noise produced by the inductance of the wire. The noise is then suppressed, as the electric fields generated by the PA2670NL counteract each other.

The PA2670NL is a low profile part making it easy to install in tight places, such as automotive electronic circuit boards. It is also rated for a very high insertion loss, making it well suited for high frequency applications. Furthermore, it has an autocompensation feature which ensures that the performance stays consistent over time.

The PA2670NL is an attractive option for applications requiring high performance and high reliability and is one of the most popular Common Mode Chokes available today. It provides excellent EMI rejection, low insertion loss, and high reliability, making it the ideal choice for a wide range of applications.
