Common Mode ChokesCommon mode chokes are devices that use coils and ferrites or cores to block common-mode currents between two different circuits. Common-mode currents are unwanted currents on shielded cable that can create interference and noise issues. Common mode chokes are used to isolate and protect devices from noisy power and signal lines. Common mode chokes are used in many applications, such as automotive, industrial automation, medical applications,meters, and other communications systems.One type of common mode choke is the RN212-4-02. This device features an impedance of 12 ?H, a frequency range of 20 kHz to 20 MHz, and a DC resistance of 0.3 ohms. It is a surface-mount common mode choke with small dimensions, suitable for application in a wide variety of areas. It provides high performance for differential signal transmission, attenuates common mode interference, and reduces the EMI. The RN212-4-02 provides excellent noise suppression as well as high common-mode rejection across the entire frequency spectrum. The working principle of the RN212-4-02 is based on the inductance created by two windings on a ferrite core. The inductance is used to reduce common-mode noise on differential signal transmission lines. The windings are arranged with diametrically opposite poles so that the magnetic fields of the coil cancel each other out. This helps to achieve the highest common-mode noise suppression. Thanks to its small size, the RN212-4-02 is suitable for space-constrained applications. It can be used in automotive electronics, communication equipment, digital displays, and medical equipment. The RN212-4-02 can also be used in other EMI-sensitive applications, such as measurement equipment, instrumentations, and industrial automation.The RN212-4-02 offers excellent performance due to its low DC resistance and high common-mode noise suppression. It is designed to reduce the noise on the two wire lines with minimal impact on the differential signal integrity. The RN212-4-02 is RoHS compliant and meets all the necessary quality requirements. It is designed for ease of use, with features such as a solderable plating and surface mounting. Common mode chokes are an essential component in many applications, and the RN212-4-02 is a reliable and cost-effective solution for reducing common-mode noise. This component has excellent common-mode noise suppression and signal integrity, allowing it to be used in a variety of applications. The RN212-4-02 is ideal for EMI-sensitive applications that require high common-mode noise suppression and low DC resistance.
