Common Mode Chokes

Common Mode Chokes are electrical components that are designed to reduce the transmission of electromagnetic common mode signals along a conductor or pair of conductors. The B82614R2801A030 is a type of Common Mode Choke that is being used in various applications. It is widely used for DC power supply lines, remote power supply lines, and high speed signal lines.

Application Field

The B82614R2801A030 Common Mode Choke is primarily used in DC power systems for filtering and attenuating electrical noise and harmonic interference in automotive power systems, avionics, and Industrial control applications. Additionally, it is used for signal line noise suppression, data signal filter, and RF signal filter. This component also suppresses high frequency noise without disturbing normal signals.

Working Principle

The B82614R2801A030 Common Mode Choke consists of two coils, which are wound in opposite directions in a bobbin. The differential signal passes through the coils in a balanced form, thus providing isolation to the differential signal while attenuating the common mode noise. The choke also provides a low impedance path for high frequency noise, thus reducing the transmission of the noise through the system. The low impedance path provides an electromagnetic shield that blocks the passage of common mode signals.

The high frequency noise produced by the source of noise is intercepted by the coils of the B82614R2801A030 Common Mode Choke and the current is thereby dissipated. The dissipation of current takes place in the form of heat, thereby eliminating the common mode signals. This process has the effect of providing a high level of attenuation to both AC and DC signals.

In addition to its noise suppression capabilities, the B82614R2801A030 Common Mode Choke can be used to provide impedance matching or signal balancing. The choke impedance is limited to a few ohms, which reduces the effect of ground loops and thereby allows signals to be routed between two different systems with minimal interference.

Conclusion

The B82614R2801A030 Common Mode Choke is a versatile component that is widely used in the automotive, avionics, and industrial control fields. It is an efficient tool for suppressing electrical noise and harmonic interference, providing impedance matching, or signal balancing. Its low impedance and electromagnetic shielding capabilities make it ideal for a wide range of applications.
