ET3542-056

Common mode chokes are electromagnetic components used for suppression of differential and common mode noise, and they are an efficient solution for noise suppression in electronically switched systems. ET3542-056 is one of the common mode chokes developed by Amphenol Advanced Sensors. It is designed for various industrial applications and its good performance provides protection against interference in both common and differential modes.The ET3542-056 is a three-core choke, which consists of a two-turn common-mode choke and two one-turn differential-mode chokes. The two enclosed cores sandwich a toroidal ferrite core. The unique three-core design of the ET3542-056 allows for high inductance values, high common mode attenuation, and wideband differential mode noise suppression. This makes it especially suitable for use in the automotive industry, industrial motors, generators, and other industries that require high levels of noise suppression.The ET3542-056 works by reducing noise interference in two ways. First, it reduces common mode noise between two signal lines by reducing the common mode voltage. This is done by using a common mode choke to create an inductive impedance which reduces the voltage on both signal lines. Secondly, it reduces differential mode noise between the two signal lines. Differential mode noise is caused by imbalance between the two signal lines, so the choke works to reduce this imbalance and create a consistent signal between the two lines. The ET3542-056 is rated for a current of up to 20 Amps and is available in a wide range of inductance values. It also has a wide operating temperature range from -40°C to +125°C, making it suitable for use in multiple applications. It has low dV/dt noise suppression capability, making it an ideal choice for automotive applications such as electric power steering and ABS controllers.In conclusion, the ET3542-056 is a reliable and powerful common mode choke designed for use in a variety of different applications. It is capable of reducing both common mode and differential mode noise, making it an effective noise suppression device. The wide operating temperature range and high current rating make it suitable for many applications, while its unique three-core design ensures high levels of noise suppression.
