Common Mode Chokes

Common Mode Chokes, also known as CM chokes or line filters, are electrical components designed to suppress common mode noise in electronic systems. Common mode noise is generated from sources such as electromagnetic interference (EMI) or electrostatic discharge (ESD) traveling down transmission lines, and it is often damaging to sensitive PCB components. Common Mode Chokes come in various forms and the B82726S2243A020 is one such form.

Application Field of B82726S2243A020

The B82726S2243A020 is an automotive industry-grade common mode choke designed for use in electric vehicles (EVs). As electric vehicles are becoming increasingly popular, there is more demand for components designed specifically for the EV industry. The B82726S2243A020 is one such component designed to suppress common mode noise to protect sensitive components from EMI and ESD. The choke is equipped with two separate windings, which makes it suitable for use in converters or AC/DC power supplies.

Working Principle of B82726S2243A020

The working principle of the B82726S2243A020 involves the suppression of common mode noise by the transfer of the noise from one winding to the other in a differential structure. The noise-carrying current flows in two directions – the source and return paths – through the two separate windings of the choke. The choke creates a magnetic field around each winding, which works to transfer the common mode noise away from the sensitive components. The magnetic field created by the choke inductance separates and dissipates the common mode noise, providing protection from EMI and ESD.

Benefits of B82726S2243A020 Choke

The B82726S2243A020 choke offers several benefits for automotive applications. First, it has a compact size and weight, making it ideal for use in electric vehicles. Secondly, the differential construction reduces the overall size of the component and decreases the number of parts needed. The choke also features a robust shield with double-sided contacts, which provides additional protection from EMI and ESD. Finally, the B82726S2243A020 offers a wide selection of inductance ranges, ensuring that it is suitable for a variety of automotive applications.

Conclusion

In conclusion, the B82726S2243A020 is an automotive grade common mode choke specifically designed for use in electric vehicles. The choke offers several advantages, such as enhanced protection from EMI and ESD, a compact size and weight, and a wide selection of inductance ranges. This makes the B82726S2243A020 an ideal choice for suppressing common mode noise in automotive systems.
