  1. What is an EMI power filter?

A: An EMI power filter is a component used to mitigate electromagnetic interference (EMI) and reduce disturbances in a power line. Typically constructed with inductors and capacitors, these filters are collectively known as passive EMI power filters.

  1. Why do we need EMI filters?

A: Electromagnetic compatibility (EMC) is crucial for assessing the quality of electronic products. Incorporating EMC design in power systems enhances overall anti-interference capabilities, extends system lifespan, and ensures safe operation. EMI filters play a vital role in achieving good electromagnetic compatibility.

  1. Where should I place my EMI filter?

A: A power line or mains EMI filter should be positioned at the power entry point of the equipment it is installed in, preventing noise from exiting or entering the equipment. Essentially, an EMI filter comprises capacitors and inductors.

  1. How does an EMI filter work?

A: EMI, or Electro-Magnetic Interference, refers to unwanted electrical signals that can be conducted or radiated emissions. Capacitors offer a low-impedance path to redirect high-frequency noise away from the filter's input, either back into the power supply or into the ground connection.
