Common Mode Chokes (CMC) are used in a wide range of applications, from power supply and communications systems to automotive and aircraft electronics. The CMT908-H4 is a type of CMC specifically designed to reduce the common-mode current that flows through electrical systems. This article will discuss the application fields and working principle of the CMT908-H4.

One application of CMT908-H4 is in industrial power supplies, where they are used to provide excellent EMI/RFI noise suppression. The choke reduces the amount of current in the common-mode by up to 70%, allowing for superior performance from the power supply. In addition to its use in power supplies, the CMT908-H4 is also widely used in telecommunications systems, such as local area networks (LANs) and modems. The choke reduces the common-mode voltage and current across Ethernet cables, allowing for improved EMI/RFI noise suppression.

The CMT908-H4 is also commonly used in automotive and aircraft electronics, where it can be used to reduce the noise generated by electrical components. The choke excels at suppressing high-frequency emissions, which can be detrimental to the performance and reliability of these kinds of systems. The choke also helps reduce the amount of electromagnetic interference (EMI) that is released into the environment, making it a useful tool for reducing noise pollution.

The working principle of the CMT908-H4 is based on the concept of inductance. Inductance is the property of an electrical circuit that allows it to resist changes in current flow. When current is flowing through the device, an electromagnetic field is generated, which causes a voltage to be induced in the surrounding windings. This voltage opposes the changes in current, thus limiting the amount of common-mode current that can flow through the system.

The CMT908-H4 consists of two interlocking windings with a common core. One winding is designed to carry an alternating current, while the other is designed to carry a direct current. As the current flows through the device, it induces an opposing voltage in both windings, which causes the current to flow more slowly. This reduces the amount of common-mode current that can flow through the system.

The CMT908-H4 is a high-efficiency, low-cost choke that can be used in a wide range of applications. Its ability to reduce common-mode current makes it an ideal choice for power supplies, telecommunications systems, and automotive and aircraft electronics.
