EMC service

Definition: Electromagnetic compatibility (EMC)

To make practical use of electrical energy, it first must be converted into another form of energy, for instance into radiant energy (light bulbs), mechanical energy (motors) or heat. The processes of converting and transporting electrical energy generate electromagnetic fields that can radiate not only within electrical equipment but also radiate into the air or in the power grid. Fields that radiate freely can penetrate into other electrical equipment and influence its operation, effects we experience as interference. Examples of sources of such EMC interference include:
  • Electromagnetic fields intentionally generated by transmitting stations in the frequency range from kHz to 30 GHz (microwaves) and beyond
  • Lightning strikes
  • Switching operations in low-voltage networks that generate high-energy surge impulses
  • Switching operations in power-electronic circuits (switching power supplies) that lead to high-frequency, transient voltage spikes and flickers
  • A nuclear electromagnetic pulse (NEMP) resulting from an atomic explosion
  • Electrostatic discharge (ESD)
  • High-frequency signals that, for instance, arise when the loads on microprocessors are changed or during the operation of frequency converters
Manufacturers of electrical equipment must contain EMC, and the limits for interference immunity or emitted interference are established in relevant standards. SCHURTER offers the ability and expertise for ensuring EMC compliance. To prevent technical equipment from causing interference in other units through electrical or electromagnetic effects, we offer a wide range of products plus various services.


SCHURTER is a leading innovator and manufacturer of passive und active electronic components ensuring the clean and safe supply of power and ease of use of equipment.
