Common Mode Chokes (CMC) are widely used in various applications, such as switching power supplies, digital and analog signals, and EMI filters. CMCs are designed to reduce high frequency noise and common mode current in a power source or transmission line.  CMT-02203 is a type of Common Mode Choke which is suitable for applications in which shielding is not available but high common mode noise rejection is required.

The CMT-02203 is designed to achieve a high common-mode noise rejection whilst keeping its voltage and current ratings relatively low. This means that the CMT-02203 is ideal for applications that require high common mode noise rejection, yet have limited voltage and current ratings. The CMT-02203 choke can handle up to 20 A of current and a voltage rating of up to 2,000 VDC.

The working principle of CMT-02203 is based on the principle of inductance. The core of the choke consists of a number of copper windings wound in series around an iron core. This forms an inductor which stores electrical energy in the form of a magnetic field. The magnetic field created by the inductor opposes any changes to the current. Any common mode noise is effectively rejected, as the current through the inductor cannot change instantaneously in response to the noise.

The CMT-02203 is designed to have a high impedance to common mode noise, which is the electrical noise that runs through both hot and neutral electrical lines. It is important to note that the CMT-02203 is not designed to reduce any stray noise, such as RF interference or ground loops. For these types of noise, a differential mode inductor should be used instead.

The CMT-02203 is a very popular inductor for a wide variety of applications. It is well suited for use in switching power supplies, protection against overvoltage surges, and filtering out high frequency noise from cables and circuits. It is also useful in EMI/RFI (Electromagnetic Interference/Radio Frequency Interference) filters, which are designed to protect sensitive electronic equipment from interference from nearby electrical or electronic equipment.

In conclusion, the CMT-02203 is a common mode choke which is ideal for applications in which shielding is not available but where common mode noise rejection is needed. It works by storing electrical energy in the form of a magnetic field, which effectively rejects any changes to the current due to the presence of noise. The CMT-02203 is well-suited for applications such as switching power supplies, EMI/RFI filters, and protection against overvoltage surges, and it is easy to see why it is a popular choice for many different types of applications.
