Common mode chokes, such as the DLFP-0147-16D3, are passive components that are designed to mitigate electromagnetic interference (EMI) and noise. Common mode chokes work by using the principle of differential-mode (DM) and common-mode (CM) unbalance. Differential-mode signals are those signals that travel along two or more paths of equal value, while common-mode signals are those that travel along two or more paths of different value.

In the case of the DLFP-0147-16D3, common mode chokes are capable of filtering different kinds of signals, including both differential-mode and common-mode signals. Depending on the application, they are capable of attenuating, blocking, or isolating signals ranging from 10 kHz to 10 GHz.

The DLFP-0147-16D3 is characterised by its low insertion loss, high frequency-dependent power characteristics, wide band coverage, and excellent temperature stability. Because of its tight tolerance and its ease of installation, the part is ideal for applications in the automotive, aeronautical, and defense industries, as well as for general RF applications.

Common mode chokes are typically used to reduce both differential-mode and common-mode noise, and are designed to be employed in areas where both types of signals are present. This occurs, for example, in the presence of balanced audio and video lines, or in areas where high-speed communications data is transmitted.

Common mode chokes work by blocking or attenuating certain frequencies while allowing others to pass through. The amount of attenuation or blocking that a certain choke can provide depends on its construction, size, inductance value, and the type of filter circuit used. With regard to the DLFP-0147-16D3, common mode chokes are capable of providing up to 15dB of attenuation.

To achieve this, the filter is typically placed in series with the differential signal path. The choke features two separate windings, one for the differential-mode current and one for the common-mode current. These windings are usually placed in phase with each other, and the inductor is typically designed in such a way that it produces an effective AC magnetic field that causes the common-mode noise to be more effectively filtered.

The amount of filtering that the DLFP-0147-16D3 offers is dependent on its size, type of inductor used, and the value of the inductor. Different types of inductors may be used, including air-core, ferrite-core, or Laminated-core inductors. The size of the inductor will affect how much filtering it can offer. As the inductor\'s size increases, so does its ability to attenuate noise.

The DLFP-0147-16D3 is also capable of providing excellent temperature stability and wideband coverage. This makes it ideal for use in a variety of applications, including automotive, aeronautical, defense, and general RF. It is a reliable, robust component that is designed to ensure that all EMI, EMC, and RF noise is minimized.

The DLFP-0147-16D3 is a versatile common mode choke that can be used in a variety of situations. Thanks to its low insertion loss, high frequency-dependent power characteristics, wide band coverage, and excellent temperature stability, the part is ideal for automotive, aeronautical, and defense applications, as well as for general RF applications.
