Common Mode Chokes, or CM chokes, are versatile and widely used electrical components used to prevent signal interference from other circuits or components. These devices are also known as specialty inductors, line filters, or filter chokes, depending on their specific purpose. The TF1028S-162Y1R3-01 is an ideal CM choke offering a wide range of applications.

The TF1028S-162Y1R3-01 is an axial-leaded Common Mode Choke used for suppressing conducted common-mode noise signals in single-phase, two-phase, and three-phase systems. It is also suitable for Automotive applications, such as On-Board Diagnostics (OBD), CANBUS, MOST Bus, and AUTOSAR. In these applications, the TF1028S-162Y1R3-01 is used to minimize EMI-related coupling between accessories and sensitive ECUs. It features a ferrite material core, good In-Phase/Crosstalk balance, and low winding resistance for optimal performance.

The TF1028S-162Y1R3-01 shares a few common features of CM chokes. The device consists of two windings that are electrically connected and typically arranged so that they are magnetically linked. This magnetic coupling of the windings forms an inductance along both windings, creating a natural impedance to electromagnetic radiation. This is helpful in mitigating the effects of Electromagnetic Interference (EMI) on the signal.

The operation of the TF1028S-162Y1R3-01 is based on the fact that it has two separate windings that react differently to current flowing in them. The device will block or attenuate common-mode signals travelling along either winding. The windings are arranged so that a current travelling through one winding will create a magnetic field that opposes the current travelling through the other winding. This cancellation reduces the radiated noise, resulting in improved signal integrity.

The delivered performance of the TF1028S-162Y1R3-01 is usually measured by the device’s Insertion Loss (IL). IL is the measure of the attenuation provided by the inductance of the device, and is often reported in decibel (dB). Lower Insertion Loss values indicate better common-mode suppression.

The TF1028S-162Y1R3-01 presents a reliable common-mode noise suppression solution for multiple industries. Its wide range of application possibilities and reliable performance makes it an optimal device for companies seeking to reduce EMI-related coupling between devices or components.
