Common Mode Chokes (CMCs) are widely used in a variety of applications, ranging from telecommunications to aircraft and vehicles. The ET3542-055 is a type of CMC designed to provide high-isolation performance in severe electromagnetic interference (EMI) environments. As a broadband EMI filter, the ET3542-055 performs very well in suppressing common-mode noise and providing high-attenuation performance across a broad frequency range.

CMCs fundamentally work on the principle that current will tend to flow in the same direction through two paths. By changing the inductance of one of the two paths, a differential mode current can be established. The ET3542-055 consists of two high-inductance windings provided on two separate high-permittivity cores. This will create higher impedance to common-mode noise than that encountered for lower impedance circuits. Consequently, the ET3542-055 provides high-isolation performance when used in conjunction with other common-mode filters, such as differential-mode filters.

The ET3542-055 is ideal for applications that require both high isolation performance and low insertion loss from common-mode signals. It is an ideal solution for TV systems, satellite systems, wireless transmissions, and other EMI-sensitive communications systems. It is especially useful in harsh electromagnetic environments, such as those encountered on aircraft. In these environments, the ET3542-055\'s two high-permittivity cores and high-performance windings enable it to provide high isolation performance even in the most demanding environments.

The ET3542-055 is also well suited for applications requiring isolation performance across a broad frequency range. It is designed to provide high-attenuation performance from as low as 10 MHz up to 6 GHz, making it ideal for a wide range of communications and broadcast systems. It is also capable of suppressing both common-mode and differential-mode EMI noise.

In addition, the ET3542-055 is designed for high reliability and excellent thermal characteristics. It is constructed from high-quality components with low dielectric loss, ensuring superior signal integrity and reliability. Additionally, its construction is designed to maximize thermal efficiency, ensuring that the ET3542-055 remains cool to the touch under normal operating temperatures.

The ET3542-055 is a flexible and reliable CMC that is ideal for high-isolation performance in demanding electromagnetic environments. Its high-attenuation performance across a broad frequency range, low insertion loss, and excellent thermal characteristics make it an attractive solution for a variety of communications and broadcast applications.
