And what’s more, we offer next day delivery to help you avoid delays and keep you moving!

"EMC" - THE BASICS

Electromatic Compatability (EMC), often also reffered to as Electomagnetic Interference (EMI), is a crucial aspect to consider when designing electronic products. It ensures that electronic devices and systems function properly and safely in the same electromagnetic environment, without interfering with each other or causing harm to users.

Strict EMC conformity is also often required by product regulations to prevent interference with other devices or systems.

emcfixSHOP Ethernet Filter

Example: There is interference on your ethernet cable - you could put an emcfixSHOP Ethernet In-line EMC Filter in there to reduce the effect of any noise on the line.

EMISSIONS

EMC is generally split into two categories - Emissions and Immunity.

Emissions in the context of EMC refers to the generation of electromagnetic noise by electronic products and systems. These emissions can be either deliberate or accidental and can cause interference with other devices or systems in the same environment.

There are two types of emissions that products are required to comply with - Radiated Emissions and Conducted Emissions.

More information can be found on our Dedicated Emissions Help Page.

emcfixSHOP Ferrite

Example: Power cables can act as a nice path for electromagnetic noise generated inside a product or system which can cause interference with other nearby devices. Noise can often be reduced by putting Ferrites on the power cable - see our ferrite collection here. Ferrites come in all shapes and sizes, please speak to us if you need any help.

IMMUNITY

Immunity refers to the ability of electronic products and systems to function properly in the presence of electromagnetic interference/noise from external sources (often other electronic products and systems).

There are a number of types of immunity requirements that your product must meet, such as:

  • Conducted Immunity
  • Radiated Immunity
  • Electrostatic Discharge (ESD)
  • Electrical Fast Transients (EFT)
  • Magnetic Field Immunity
  • Voltage Dips and Interrupts
  • Surges

More information can be found on our Dedicated Immunity Help Page.

Varistor (48V DC, 5.4W)-Würth-emcfix shop

Example: A product with sensitive electronics is malfunctioning when other equipment on the same power network is being switched on and off. The performance of a product when subjected to voltage fluctuations and power surges would be tested during EFT and Surge testing and Varistors are often a useful addition to help protect your product - see our selection of Varistors here. Varistors are available with different properties to amtch the requirmeents of different systems, please speak to us if you need any help.
