FAQ
1. What is an EMI power filter?
A: EMI power filters are electromagnetic interference mitigating
components used to reduce the disturbances in a power line. They
are commonly made of inductors and capacitors and are collectively
called passive EMI power filters.
2. Why do we need EMI filter?
A: Electromagnetic compatibility (EMC) is an important indicator to
measure the quality of electronic products, and it has increasingly
become the key in the design of electronic products. In the design
process of the power system, the introduction of electromagnetic
compatibility design can improve the overall anti-interference
ability of the power system, extend the service life of the system,
and ensure the safety of use. Therefore, the electromagnetic
interference filter is a device that provides good electromagnetic
compatibility.
3. Where should I place my EMI filter?
A: A power line or mains EMI filter is placed at the power entry
point of the equipment that it is being installed into to prevent
noise from exiting or entering the equipment. Essentially, an EMI
filter is made up of two basic types of components–capacitors and
inductors.
4. How does EMI filter works?
A: EMI, or Electro-Magnetic Interference, is defined as unwanted
electrical signals and can be in the form of conducted or radiated
emissions. The capacitors provide a low impedance path to divert
the high frequency noise away from the input of the filter, either
back into the power supply, or into the ground connection.
