This intense wave may damage semiconductor components and signal processing circuitry that is found in electronic and electrical equipment. Electromagnetic Radiation (EMR) The emission of energy in the form of electromagnetic waves. It consists of oscillating electric and magnetic fields propagating at ...
Shielding is essential in electrical engineering to protect electronic devices from electromagnetic interference (EMI) and radio frequency interference (RFI). EMI and RFI shielding disrupt the proper functioning of devices and can cause unintended operations to occur. Both can also adversely affect the ...

EMI Thermal provides a full range of EMI, EMC & RFI shielding products to meet all of your requirements, wherever you are in Europe.
Reducing Electromagnetic interference (EMI) in switch mode power supplies can be a challenge, because of the very high frequencies that are involved. Electrical components behave differently than expected, because the parasitic effects of the components often play an important role. This application ...
Figure 3: A full 360° termination (top) is needed for maximum shield effectiveness, rather than the quick-and-easy pigtail ground connection (bottom). (Image source: ResearchGate) The need for termination at both ends with non-gapped 360° coverage is due to physics: as operating frequencies...
In a circuit, components like capacitors are used to store such form of energy. A charged capacitor has an internal electrical field, whose intensity is related to the voltage applied by the following relations (calculated for a parallel plate capacitor): Eq: Relation between electric ...
but it is even more complicated with an irregular wave form of a TRIAC dimmed input and with less than “full load”. Actually the standard doesn´t define the test conditions in the case of dimming and simply ignores it. So test houses doing the certifications also do not ch...
When it comes to the world of electronic equipment, one undesirable element that’s sometimes found in electrical setups is known as electromagnetic interference (EMI). EMI can have a negative effect on performance and lifespan of various kinds of electrical equipment, but there are also several...
