Common Mode Chokes are widely used in modern engineering in many industries. A common mode choke, such as the RN214-2-02, is used to suppress common mode noise over a wide frequency range while allowing differential mode signals to pass. Common mode chokes can be used to reduce harmful EMI (Electromagnetic Interference), as well as to reduce high frequency switching noise in a switching power supply.

The RN214-2-02 choke works using two principles. The first is called inducer effect, which occurs when a conductive wire is wound around a core, such as iron or ferrite, thus creating a temporary magnetic field. This magnetic field interacts with the current passing through the wire and creates an opposing voltage. This opposing voltage will, in turn, reduce the current in the wire, thus suppressing the noise.

The second principle of the RN214-2-02 choke is called eddy current effect, which occurs when a current generated in a coil passes through a ferrite core. Magnetic flux is generated in the core material by this induced current, resulting in an opposing voltage, which reduces the noise. Thus these two principles form a “balanced” structure, which effectively suppresses the noise.

Common mode chokes from RN214-2-02 are mainly used in medical, automotive, aviation, and industrial applications. They are used to prevent common mode of noise from interfering with sensitive signals, as well as to reduce the switching noise generated by switching power supplies. Also, the RNC214-2-02 is a UL-certified common mode choke, thus ensuring the highest standards of safety and effectiveness.

In summary, the RN214-2-02 is a common mode choke used for suppressing common mode noise. It works using the inducer effect and eddy current effect to generate an opposing voltage to reduce the current in the wire, thus effectively suppressing the noise. The RN214-2-02 is widely used in many industries, mainly for medical, automotive, aviation and industrial applications, as it is UL-certified and thus guaranteeing safety and effectiveness.
