Common mode chokes, also known as common mode filters are energy-efficient EMI filters that significantly reduce noise and crosstalk within a power system. The RN152-10-02 model is the latest in a series of devices that effectively suppress common-mode noise in applications ranging from signal transmission lines to systems with high-speed signals. It is designed for applications that require a high-frequency common-mode filter and fast response.

This device utilizes a motor structure that produces magnetic flux in the center of the motor coil, thereby suppressing common-mode current noise. The motor structure is based on a toroid configuration which provides the maximum efficiency in terms of filtering performance. The RN152-10-02 has a gray color and measures 4.0 × 4.0 × 2.2 inches with a total weight of 1.7lbs.

The working principle of this common mode choke is based on principle of transformer. Both primary and secondary windings are wound around a single core, which is usually a ferrite core. The windings do not have any electrical connections, but they interact with each other due to the presence of the core\'s magnetic flux. The winding is in opposite direction, meaning the current at the end of one winding adds up with the current at the end of the other winding. When a DC voltage is applied to the primary winding, the current in the windings create a magnetic field which interacts with the magnetic field from the core, resulting in a voltage in the secondary winding. This voltage opposes the applied DC voltage, thus resulting in a reduced voltage across the primary winding, which is the desired effect.

The core of the RN152-10-02 device is wound with 10 turns of secondary windings. The primary winding is also 10 turns, but the current direction is opposite. Therefore, the overall inductance of the winding is 10 times the mutual inductance of the winding. This increased windings result in minimal audible noise at higher current levels, when compared to conventional common mode chokes. The RN152-10-02 also offers a low insertion loss, high ripple current, and fast penetration of common-mode noise.

The RN152-10-02 common mode choke is specifically designed for applications where the common mode current is above 50mA. It employs a patented technology to effectively reduce audible noise and deliver excellent filtering performance, even in systems with high-speed signals. In addition, this device can effectively suppress AC power line noise and conducted radio-frequency interference in signal lines. This makes it an ideal device for a wide range of applications, such as automotive, telecommunications, medical, and consumer electronics.

The RN152-10-02 is a robust solution for suppressing common-mode noise in modern power systems. This device offers excellent filtering performance with low insertion loss, high ripple current, and fast penetration of common-mode noise. It is designed for applications that require a high-frequency common-mode filter and fast response, making it ideal for a wide range of applications.
