Common Mode Chokes are electromagnetic devices used to prevent common mode currents from flowing in a system. They are comprised of two or more coils wound around a single core, and they provide electrical isolation between two conductors. PLY10AN1121R8R2B is a common mode choke often used in high frequency filtering applications, such as telecom, automotive, aerospace, and power electronics.

The PLY10AN1121R8R2B choke is constructed using five specially wound ferrite beads and a single central core. The five ferrite beads are wound together in a toroid-like shape, and they contain a 2.1R8R2B core material, which reduces the inductance and increases the quality of the choke performance. The core is made of ferrite powder and contains a dielectric oil, which helps to reduce noise and ensure effective frequency filtering. The four outer coils on the device are wound in a way that they will oppose common mode currents, while the fifth coil provides additional impedance to further prevent common mode currents from flowing.

When a voltage is applied to the choke, the ferrite material in the core creates a magnetic field around the core. This magnetic field then generates a voltage across the supplemental coil and it increases the overall inductance of the device. This inductance reduces the amount of current that can flow between the two in-phase conductors, thereby providing effective filtering of the voltage signals. Depending on the amount of inductance introduced by the PLY10AN1121R8R2B choke, it can provide up to 100dB of attenuation at particular frequencies. This makes the device especially suited to filtering RF signals in telecom applications, such as 5G cellular networks.

The PLY10AN1121R8R2B is a common mode choke that is designed to help reduce the amount of common mode currents in a system. It is constructed using five wound ferrite beads and a single central core, and it provides up to 100dB of attenuation at particular frequencies. This makes it an ideal choice for high frequency filtering applications such as telecom, automotive, and aerospace.
