Common Mode Chokes (CMC) are electromechanical electrical components used to control electrical current. They are commonly used in power electronics circuits in applications such as switch-mode power supplies (SMPS), motor drives, and various other electrical and electronic systems. In particular, CMCs are used to control common-mode noise in higher frequency applications, providing an economical yet effective solution for EMI (electromagnetic interference) mitigation.

The HM28-42056LF is one of the most common CMCs used today. It is a high performance, ultra-low profile CMC designed to help reduce radiated and conducted EMI/RFI noise in switching applications. It is suitable for use in a variety of electronic and electrical products, ranging from small to large-scale systems. This CMC is specially designed with a wide bandwidth, extended temperature range, low profile, and high current capability to provide excellent EMI/RFI suppression and current control which would otherwise require the use of larger, more expensive CMCs.

The HM28-42056LF works by passing the current it is controlling through magnetic loops which create a resistance to changes in current. This is done by limiting the amount of energy that can flow along a given path to a certain amount. This prevents high frequency “noise” from traveling along the path, which can disrupt the functioning of circuits. The loops contain a ferrite core which helps to increase the magnetic field and further increase its suppression capability.

The HM28-42056LF also features an RFI suppression circuit which helps to reduce interference from strong electromagnetic fields. This feature is particularly important for applications that require a high immunity to electromagnetic interference. It is also equipped with a secondary suppression circuit, which offers even greater protection against EMI/RFI noise.

In summary, the HM28-42056LF is an effective and economical EMI/RFI power noise suppression and current control solution. It features a wide bandwidth, extended temperature range, low profile, high current capability, and RFI suppression circuit which allow for accurate and reliable current control. This makes the CMC suitable for a variety of electronic and electrical applications, making it a popular choice for power electronics and other applications where EMI/RFI noise must be reduced.
