Common Mode Chokes have been in use for many years across a wide range of electrical and electronic applications, greatly improving system performance. One such choke is the FB20011-3B Common Mode Choke, with its specialized application fields and working principes.

The FB20011-3B is an advanced common mode filter and power line noise suppression component capable of providing high performance power line noise filtering and isolation between components. It is designed for use in applications where an isolation transformer is required to reduce high-frequency resonant coupling between two components on a shared circuit. This device is also ideal for protecting sensitive audio and video circuits against power line noise.

The unique features of the FB20011-3B allow it to be used in various application fields, such as automotive, industrial, military, and aviation, where high-frequency power line noise is present. This type of common mode choke can be used in a broad range of applications including radio frequency interference (RFI) attenuation, EMI/RFI filtering, power line harmonic filtering, and power cycling protection.

The FB20011-3B has a working principle that involves the ability to act as a low-pass filter. This is accomplished by forcing current within a coil of multiple turns of wire in such a way that it creates a path for energy to pass on only one direction. The FB20011-3B common mode choke uses this principle to suppress noise with a frequency of 200kHz or higher. As a result, it effectively removes unwanted high-frequency noise, allowing airflow and ensuring proper signal delivery.

In addition, the FB20011-3B is able to provide protection against power cycling, meaning that it will protect a circuit from the possibility of interruptions caused by power surges, outages, or other electrical disturbances. This ensures consistent signal delivery and prevents any data loss or circuit degradation.

The FB20011-3B is an efficient and reliable common mode choke and is ideal for use in applications where a high level of noise suppression or isolation is required. Its specialized application fields and working principle make it a powerful component for ensuring optimum signal delivery and protecting sensitive circuits from electrical disturbances.
