Common mode chokes, often abbreviated as CMCs, are device used to reduce or eliminate common-mode noise in electronic signals. RN202-1.5-02 is a CMC designed for reducing noise on Ethernet cable applications.

The device is small in size, light in weight and low in cost and thus is widely used in data communication networks. It consists of two ferrite trifilar windings, housed in a rugged plastic shell, and the device also features a protective dielectric element to increase protection against voltage surges.

RN202-1.5-02\'s application field is for noisy Ethernet cables. These cables typically carry digital transmissions, which require noise-free transmission for proper communication. The device acts as a choke to reduce the amount of noise and interference on the cable, thus improving signal quality and network performance. The common mode choke can also be used to help eliminate ground loops and reduce EMI on industrial control systems.

The working principle of the RN202-1.5-02 CMC is based on the concept of inductive reactance. Inductive reactance is defined as the opposition of current flowing in a circuit due to an induced voltage. This impedance opposes both the common-mode currents as well as the differential-mode currents. It is this characteristic of inductive reactance that allows the device to reduce or eliminate common-mode noise in the signal and thus improve signal quality and performance.

The RN202-1.5-02 CMC works by using a combination of magnetic and electrical components to reduce common-mode noise in the signal. The device is composed of two ferrite trifilar windings, each consisting of two coils wound with high-resistance insulation. Each coil is wrapped around a core of ferromagnetic material, which creates a magnetic field that interacts with the signal\'s electric current. This creates a barrier to the flow of current and increases the impedance of the signal. This impedes the flow of common-mode noise through the signal, thus reducing its strength and eliminating it entirely.

The RN202-1.5-02 CMC is an ideal solution for eliminating noise on Ethernet cables. Its small size and low cost make it perfect for applications where there is limited space and a small budget. The device\'s protective dielectric element increases its protection against voltage surges, making it ideal for industrial control systems. The working principle of inductive reactance also ensures that the device reduces common mode noise in the signal and improves the signal quality and performance of the system.
