| A common mode choke is an electronic component used to filter electromagnetic interference (EMI) |
| and radio frequency interference (RFI) from electrical circuits. It is also known as a line filter or a noise filter. |
| The common mode choke consists of two coils wound on a magnetic core. |
| The coils are wound in such a way that they create a magnetic field that opposes the flow of current in both directions. |
| This means that the common mode choke blocks any current that is common to both the input and output of the circuit, |
| while allowing the differential mode current (the difference in current between the input and output) to pass through. |
| Common mode chokes are used in a wide range of electronic devices, including power supplies, |
| audio equipment, and data communication systems. They are particularly useful in applications |
| where electromagnetic interference and radio frequency interference can cause signal distortion, noise, |
| or other problems.By blocking unwanted noise and interference, common mode chokes can improve the performance |
| and reliability of electronic systems. They can also help to ensure compliance with electromagnetic |
| compatibility (EMC) standards, which are designed to limit the amount of interference |
| that electronic devices can generate and be susceptible to. |
