EMC

Meaning in electrical & electronics engineering, with examples

abbreviationCommon term

In electrical & electronics engineering, EMC means: Short for electromagnetic compatibility: the ability of a device to work properly in its electromagnetic environment without disturbing other equipment or being disturbed by it.

In Turkish: elektromanyetik uyumluluk, EMC

How it is used

Used in product design, testing and certification. EMC has two sides: emissions (what the product sends out) and immunity (how well it resists disturbances). Products pass or fail EMC testing in an accredited lab, and EMC is a key part of meeting the CE marking requirements in Europe.

Example sentences

  1. The prototype failed the EMC test because of emissions from the switching supply.

  2. Think about EMC early: a good ground plane and short current loops cost less than shielding later.

Common collocations

  • EMC testing
  • EMC compliance
  • pass EMC
  • EMC lab
  • EMC directive
  • noiseUnwanted random or interfering signals that mix with the signal you want and make it harder to measure or use. It can come from components, power supplies, motors or radio sources.
  • filterA circuit that lets some frequencies pass and blocks or weakens others. Common types are low-pass, high-pass, band-pass and notch filters.
  • ground planeA large, continuous area of copper on a PCB layer that is connected to ground. It gives signals a short, low-impedance return path and helps reduce noise.
  • IECShort for International Electrotechnical Commission: the global organization, founded in 1906 and based in Geneva, that publishes international standards for electrical and electronic technologies.
