<div><p>Common Mode Chokes (CMCs) are one of the most common components used in power electronics applications. This type of coil is essential for the proper functioning of digital circuits, and also plays an important role in harmonic filter networks. RN112-1.2-02 is one of the standard solutions for such applications. The coil has two pins, making it lighter and smaller, and suitable for the application in high-reliability, low-noise industrial environment.</p><h2>Application Field</h2><p>Due to its small size and weight, the RN112-1.2-02 CMC is a great choice for applications in the industrial field, such as in ships, locomotives, mobile and stationary equipment, electronic control systems, UPS systems, power supplies, and even in electric vehicle charging systems. Its optimized design helps to reduce traction noise, and improves the transient response of power supplies, making them more efficient while ensuring a reliable operation in harsh atmospheres. </p><h2>Working Principle</h2><p>The RN112-1.2-02 Common Mode Choke works by storing and delivering energy when current passes through its core. The higher the current, the greater amount of energy is stored and delivered by the component. When current passes through the core, the magnetic field generated affects the core and generates a voltage, which is transferred back to the circuit. This effect is used to reduce the amount of high-frequency noise that is generated in the circuit, as well as protect from interference caused by external sources. </p><p>The CMC also helps to reduce the generation of sparks, which are often generated when high-frequency currents pass through a circuit. The stored energy can be used to absorb the spark and reduce the amount of energy released in the circuit. This ensures that the system is not damaged by sudden, unexpected release of current. Additionally, it also helps to reduce the overall noise levels in the system.</p><p>The RN112-1.2-02 Common Mode Choke is rated for a current of up to 0.6 amps and is equipped with a ferrite core. Due to its high-performance and reliable operation, it has been adopted as the standard solution in many industrial and power electronics applications. </p></div>
