Common Mode Chokes, or CMCs, are components that are used to attenuate ground noise caused by power inductors. This can be especially important in high- currentsituations, where a large amount of noise will occur due to the inductive components. HM85-37102LFTR is one of the most popular common mode chokes, and it is used in a variety of applications.

In terms of its applications, the HM85-37102LFTR is primarily used for suppressing differential mode noise as well as power harmonics that can disrupt power supply systems. It is also used for suppressing noise on high-speed signals, such as USB and Ethernet, as well as for reducing power losses in switching power supplies.

In terms of its working principle, the HM85-37102LFTR is made up of two main coils, each of which has a core around it. These coils are placed in series, so that they are both in the same magnetic field. When current is applied to the coils, the magnetic flux is shared between them, resulting in inductance and inductive reactance. This inductive reactance results in an impedance, or opposition, to the current.

The design of the HM85-37102LFTR also includes a shield to prevent noise from traveling through the common-mode inductor. This shield is typically made of aluminum foil, and it helps to ensure that the noise is isolated and completely blocked from the rest of the circuitry.

The HM85-37102LFTR is often used in circuits that require very low frequencies such as power supplies, audio applications, and RF applications. It is also useful for suppressing noise and harmonic distortion in power supply systems.

Overall, the HM85-37102LFTR is a popular and reliable common mode choke that can be used for suppressing differential mode noise as well as power harmonics. It is made up of two coils placed in series, with an aluminium foil shield to prevent noise from travelling through the common-mode inductor. It is also useful for suppressing noise and harmonic distortion in power supply systems, and is often used in circuits that require very low frequencies.
