Common Mode Chokes

Common mode chokes are a type of power line filter which serves to attenuate or suppress common mode current from conducted to the ground. They are among the most widely used components in the electronic industry and are sometimes referred to as "line-to-ground" filters. Common mode chokes are made up of two wire coils connected to each other. The coils are wound in opposite directions so that they have opposing magnetic fields, causing the common mode current to be blocked.TLF14CB1030R7K1 is a type of Common Mode Choke designed and manufactured by TDK. It is made of high-performance ferrite material, and the center frequency is 10MHz. It features excellent attenuation characteristics and a wide common mode choke frequency band. This makes it a suitable solution for the use in a range of applications.

TLF14CB1030R7K1 Application Field

The TLF14CB1030R7K1 is typically used in devices such as computers, medical equipment, navigation systems, and others that need to reduce noise inside the system. It is especially useful for applications that require a high level of protection against transients and surges in power and signal line.The device is specifically designed to suppress common mode signals and prevent them from interfering with power and data lines. This will help reduce the noise in the system and prevent unwanted transients from interfering with operation.The TLF14CB1030R7K1 is also used in industrial automation systems, since it can protect them against disruption caused by power line transients and surges. Furthermore, the device is useful in military and aerospace applications, where it can help reduce the effects of electro-magnetic interference (EMI) and radiated emission.

TLF14CB1030R7K1 Working Principle

The TLF14CB1030R7K1 works by suppressing common mode noise on the power line or signal line. Common mode noise refers to noise which flows in both directions on the line. It is this type of noise that causes disruption and noise interference.The TLF14CB1030R7K1 uses two separate wire coils wound in opposite directions. The opposing magnetic fields created by the coils cause the common mode currents to be blocked. This is because the opposite magnetic fields will oppose the flow of common mode current. The effect is that the common mode current can not flow freely and is attenuated.The severity of the attenuation will depend on the frequency of the common mode noise. The higher the frequency, the more severe the attenuation. This makes the device especially suitable for applications where the frequency of the noise is known.The device also features excellent attenuation characteristics and a wide common mode choke frequency band. This makes it a suitable solution for the use in a range of applications, especially those that require a high level of protection against transients and surges.

Conclusion

Common mode chokes such as the TLF14CB1030R7K1 are among the most widely used components in the electronic industry. They are designed to suppress common mode noise in order to reduce interference and provide protection against transients and surges. The TLF14CB1030R7K1 is particularly useful for applications that require a high level of protection due to its wide frequency band and excellent attenuation characteristics.
