Common Mode Chokes are electrical components that reduce or block the flow of alternating current (AC) in electric circuits. Common Mode Chokes are used to reduce noise and prevent signal interference caused by common-mode currents on power and signal lines. The ELF-21N006A is a type of common mode choke that provides effective noise suppression for a wide range of applications in industries such as consumer electronics, automotive, medical, telecom, and military.

The ELF-21N006A is an advanced high-performance common mode choke featuring low DCR and a wide frequency response. This product is designed for very low profile, and it can be customized to fit in almost any space. Its reliability makes it suitable for high-temperature applications and high current applications. It is also suitable for applications where high isolation and filtering performance are needed. The ELF-21N006A is rated for a wide frequency range from 10 KHz to above 1.2 GHz.

The ELF-21N006A is designed with a unique structure which combines the air gap and shielding in a single unit. This provides high shielding effectiveness and low DCR while maintaining high temperature tolerances. The internal structure also includes an inductor which helps reduce common mode noise and interference in the signal path. The use of magnetically shielded cores helps reduce the effect of external magnetic fields on the signal path and provides reliable transmission of data and signals.

The working principle of the ELF-21N006A common mode choke is based on a combination of inductive and capacitive principles. The inductor acts as an electric current source, providing current to the load side of the choke while the capacitor provides a path for the current to travel. When the current passes through the choke, the inductor creates a magnetic field which inhibits the flow of current from the source to the load, thus reducing the common mode noise and interference. The capacitor also helps to suppress high frequency signals on the line, while the air gap between the cores of the inductor shield electromagnetic radiation.

The ELF-21N006A common mode choke is designed to be used in a wide range of applications including power supplies, DC-DC converters, computers, AV systems, industrial equipment, telecommunications equipment, and in medical devices. It is widely used to reduce EMI/RFI interference, reduce common mode noise, enhance signal integrity and stability, protect from voltage surges, and increase efficiency.

In summary, the ELF-21N006A is a type of advanced common mode choke designed for low profile and high performance. Its unique structure combines inductor and shielding to reduce common mode noise and interference in the signal path while maintaining reliably transmissions and stability. It is suitable for a wide range of applications such as power supplies, computers, AV systems, industrial equipment, and medical devices. It is widely used to reduce EMI/RFI interference, reduce common mode noise, enhance signal integrity and stability, protect from voltage surges, and increase efficiency.
