Common Mode Chokes, also known as Common Mode Filters, are devices that are typically used in power electronics applications for the purpose of eliminating unwanted noise, particularly at higher frequencies. They are usually inserted between the input or output of a power supply circuit and ground, and their purpose is to block, pass, or reduce common-mode interference. Common mode choke RN143-1-02 are widely used in a variety of power and electronic applications including air-conditioning, lighting, motors, etc.

The construction of RN143-1-02 Common Mode Choke consists of a closed magnetic loop, which in turn consists of three inductors. One inductor is connected to one of the two terminals, while the other two inductors are connected in series. This magnetic loop contains three windings with each winding arranged in a different way. This construction allows the device to block the same frequency of interference in both directions. The shape and size of the magnetic loop are designed to take into account the size of the interference signals and the operating environment of the device.

The working principle of RN143-1-02 Common Mode Choke is based on the fact that, at any given frequency, the same amount of energy flowing in either direction will experience an identical amount of current when flowing in spiral paths around a magnetic loop in air. This current will induce a voltage in opposite directions in both windings of the inductor resulting in an opposing voltage in the two leads, thus blocking any common-mode interference at the selected frequency.

RN143-1-02 Common Mode Choke is mainly used in power supplies to suppress the differential mode noise and to reduce EMI (electromagnetic interference) emission, thus improving system stability, performance, and reliability. It can also be used to reduce power consumption, improve signal integrity, and reduce noise at higher frequencies. This type of Common Mode Choke is also used in other applications such as signal transmission, medical equipment, and automotive systems.

Common Mode Choke RN143-1-02 are available in a wide range of sizes, shapes, materials, and designs. They are easy to install, durable, and can be used both indoors and outdoors. They offer superior noise suppression and are used for both single and multiple phase power supplies. The correct selection of the Common Mode Choke ensures reliable operation and maximum performance of the system.
