Common Mode Chokes are electrical components which are used for filtering radio frequency interference in low-power applications. They are also known as common mode inductors, common mode filters or CMFEs (common mode filter elements). Among other uses, they are used to suppress noise in power supplies and audio circuits, and to reduce crosstalk between the conductors of a system.The RN143-6-02-1M8 is a type of Common Mode Choke. It is designed to filter common-mode noise from low-power applications such as AC/DC converters, switch-mode power supplies, and high-speed digital circuits. It is a surface mount device, with a solid body composed of ferrite material for high efficiency.The RN143-6-02-1M8’s application field is mainly filtering radio frequency interference (EMI) in low-power applications, which typically operate at frequencies lower than 1 GHz. The EMI filter blocks unwanted high-frequency noise and keeps it away from the sensitive components within the circuitry. It can also block electromagnetic interference (EMI) that may interfere with the operation of other equipment.The RN143-6-02-1M8 works by rejecting common-mode signals and passing through the differential-mode signals. It consists of two windings which are electrically isolated and arranged in a symmetrical geometric pattern. This arrangement provides a high degree of common-mode noise rejection, while allowing differential-mode signals to pass through.The working principle of the RN143-6-02-1M8 consists of a series of inductors which are used to filter the common-mode signals and reject them. As the currents flow in the inductor, they generate a magnetic field which acts as a filter. The inductor’s internal resistance reduces the voltage drop and improves the efficiency of the filter. At the same time, the two windings are wound in opposite directions to form a second filter which rejects all even-order harmonics.The RN143-6-02-1M8 is a versatile and efficient EMI filter, and its application field and working principle make it an excellent choice for applications needing low-noise filtering in the radio frequency range. Its low-profile design also allows it to be easily integrated into circuits, further enhancing its utility.
