Common Mode Chokes, also known as a CM chokes or differential mode chokes, are used to filter out undesirable noise in high frequency applications. The TF2519HU-302Y3R0-01 is an example of a Common Mode Choke, designed for use in high speed data applications such as Ethernet. It has good attenuation in the range of several hundred megahertz.

Application Field

TF2519HU-302Y3R0-01 Common Mode Chokes are ideal for use in gigabit networks. Due to their small package size and good attenuation, they are suitable for both local and wide area networks. In addition, they are compatible with both twisted pair and coaxial cables, making them suitable for a wide range of applications.

TF2519HU-302Y3R0-01 Common Mode Chokes are also used in cable modems and power over Ethernet (PoE) systems. They can help reduce crosstalk between adjacent cables, which is particularly important in 10 Gigabit Ethernet applications.

In industrial control applications, TF2519HU-302Y3R0-01 chokes can be used to provide EMI/EMC filtering. They can be used to filter out interference in signal lines as well as power lines, providing more reliable data transmission and preventing system downtime.

Working Principle

Common Mode Chokes work by passing differential signals through two coils that are wound around a core. As the differential signal passes through the coil it induces a magnetic field that opposes the original field. This produces a reverse current which is proportional to the magnitude of the signal, thus effectively blocking high frequency noise.

TF2519HU-302Y3R0-01 Common Mode Chokes feature a ferrite core and two coils wound around it. The coils are wound in opposite directions to create an opposing force to cancel out other electromagnetic fields. This creates an impedance that blocks high frequency noise from passing through the nuclear core. The TF2519HU-302Y3R0-01 is designed to provide good attenuation at frequencies up to several hundred megahertz.

In addition, TF2519HU-302Y3R0-01 Common Mode Chokes also help to suppress high frequency switch mode noises. This is often a problem in PoE and automotive circuits where voltage levels are very unstable. The TF2519HU-302Y3R0-01 is designed to filter out these high frequency switch mode noises, providing a more reliable data transmission.

Common Mode Chokes are commonly used in high speed data applications such as Ethernet, cable modems, and PoE systems. They can help reduce EMI/EMC interference and prevent system downtime. The TF2519HU-302Y3R0-01 Common Mode Choke features a ferrite core and two coils which provide good attenuation at frequencies up to several hundred megahertz.
