Emi Filter Manufacturer Emi Filters! Soul of a Power Line for Quiet Data Flow

Emi and Emi Filter As EMI stands for electromagnetic interference, an emi filter works for minimizing the effects of electromagnetic kind of emissions or noisy disturbances which can hamper the performance of equipments and devices.emi filter Broadly, interference can be divided into common mode and differential mode.

Differential mode is a symmetrical or line to line noise, where current flows through one ac conductor and returns along the other. Common mode is a type of asymmetrical or line to ground noise exists on both ends of ac input.

How noise occurs? There are two devices in an circuit, where one produces noise and other receives it. When both of these devices exist within a mutually interactive space then Noise interference occurs. These noisy disturbances are of varied frequencies and according to it, the filter specifications needed also varies.

A Typical Design

How to prevent it? Emission Countermeasures- To prevent the noise from being produced at the noise emitting side. Immunity Countermeasures- In this case, noise and operation errors do not occur even when the device receives noise.

EMC - Electromagnetic Compatibility Both these countermesures are together referred as EMC. Electromagnetic Compatibility is the ability for not producing a kind of noise which may be tough to handle by other devices. While emission only count for the noise emitting side, where as immunity is for noise emitting side.
