Common mode chokes, also known as common mode filters, are an important type of line filter which offer a simple and cost efficient way to reduce fluctuating currents and unwanted common mode noise. The RN114-0.8-02-27M is a common mode choke suitable for low power applications which can be used to reduce conducted EMI in circuits, thus improving their overall performance. In this article, the application field and working principle of the RN114-0.8-02-27M will be discussed in detail.

The RN114-0.8-02-27M is commonly used in medical, telecom, and industrial applications, where conducted EMI suppression is required in order to maintain a high signal integrity and reduce the chances of interference. It can be used in DC/DC converter applications to reduce the output noise, while still allowing the signal to be of a high quality. In addition, the RN114-0.8-02-27M is often found in high frequency RF applications, as it can be used to reduce the chances of interference from nearby signals and provide a cleaner transmission.

The RN114-0.8-02-27M’s working principle is based on the well-known inductance-capacitance (LC) filter. This type of filter is composed of two inductive components and two capacitive components, which are connected in series to form a two-port filter. The two inductive components, known as the primary winding and the secondary winding, are connected in series at one side of the filter, while the two capacitive components are connected in series at the other side. The signal passes through the filter in a clockwise direction, and the series inductors serve to introduce resonance at discrete frequencies, which are determined by the value of the components used in the filter. This resonance is used to filter out common mode noise signals and provide a clean signal to the load.

In order to better understand the working principle of the RN114-0.8-02-27M, it is important to understand the concept of mutual inductance. Mutual inductance is a property of inductors which describes the coupling between two distinct inductors. When a signal passes through one inductor, it induces a current in the other inductor, and this current is proportional to the mutual inductance of the two inductors. By carefully specifying the parameters of the two inductors, it is possible to introduce resonance at specific frequencies, and this is how the RN114-0.8-02-27M is able to reduce common mode noise.

The RN114-0.8-02-27M is a cost effective solution for EMI and EMC problems, and is particularly suitable for low power applications. Due to its simple design and easy application, it is a popular choice for various industries. The filter offers a simple and cost effective solution for reducing conducted interference, which can have a positive effect on the performance of any circuit in which it is used.
