<div><p>Common Mode Chokes are an important part of power electronics and the application of these components is found in a wide variety of industrial and consumer applications. The purpose of these chokes is to reduce or eliminate common mode noise that may interfere with other components of the circuit. In particular, the common mode chokes play an important role in reducing high frequency noise that may be generated by power lines and monitors. RN143-4-02 is a particular type of common mode choke which is used to reduce common mode noise in the power electronics industry. This article will provide an overview of the RN143-4-02 application field, working principle and other related information.</p><p>RN143-4-02 is a common mode choke that operates over a wide frequency range of 100kHz to 40MHz. It has a low internal inductance of 140uH and is capable of propagating an instantaneous power of up to 200W when used within its specified working conditions. It has a wide variety of applications including EMI/EMC filters, switching power supply converters, TVS protection circuits and others. It is also suitable for use in switched mode power supplies, which require high noise rejection ability.</p><p>The working principle of RN143-4-02 is based on its magnetic core design and the two types of winding that it utilizes. One type of windings facilitate the reduction of high frequency noise while the other serves to reduce the low frequency noise.</p><p>The magnetic core of the RN143-4-02 is composed of two layers of ferrite. The first layer, which is the outermost layer, is used to reduce the power transmitted from the outside source. The second layer, which is the innermost layer, is responsible for filtering out the high frequency noise. The two types of winding of the RN143-4-02, which are the primary and the secondary windings, help to reduce low frequency noise and increase the choke’s inductance so that it can effectively filter out the high frequency noise.</p><p>In order to achieve maximum noise reduction, the RN143-4-02 should be installed in a secure environment with limited access to external sources of noise. It should also be securely mounted as this will help to maintain a constant level of noise reduction. Furthermore, the RN143-4-02 should be used in a balanced two-handed configuration to ensure maximum effectiveness.</p><p>The RN143-4-02 is an effective tool for reducing common mode noise in power electronics applications and other devices. It has the ability to reduce high frequency noise while also providing protection from low-frequency noise. Furthermore, its magnetic core design and two-type winding help to make it a reliable component for reducing noise in a variety of applications.</p></div>
