Common Mode Chokes are electrical components consisting of two or more coils of insulated cable wound around a solid core. Typically, they are used to reduce electromagnetic interference, or EMI, in electronic circuits. As the name implies, they are designed to prevent the flow of high-frequency, or common-mode current through the circuit.

ELM-11M020E is a high performance common mode choke designed to suppress high frequency and wideband interference associated with digital and/or analog signal lines. It is also suitable for common mode isolation between two or more cables.

ELM-11M020E is flexible enough for use in a wide range of applications. It is suitable for both surface mount and through-hole assembly and is available in multiple form factors. ELM-11M020E has a wide operating temperature range of -40°C to +105°C and can handle up to 8A peak current, making it an ideal choice for applications where high current and/or high temperature operation is required.

Additionally, ELM-11M020E offers excellent noise suppression and EMI performance. It is compliant with RoHS requirements, and it is rated to 0.25Ω. It also has a low profile design, allowing it to be used in limited space applications.

In terms of its working principle, ELM-11M020E works by inducing a voltage signal across the two windings and creates a magnetic field. This magnetic field is then used to suppress common-mode noise along the signal lines. The amount of suppression depends on various factors, such as the size of the winding, the number of turns, the core material, the type of insulation, and the frequency of the signal.

ELM-11M020E is a versatile and reliable common-mode choke suitable for use in a variety of electrical applications. Its excellent noise suppression and wide operating temperature range make it an ideal choice for applications requiring high performance and reliability. Additionally, its low profile and wide variety of form factor make it an idea choice for applications where space is limited.
