  1. One Stop Solution For Standard & Customized EMI Filters

  2. EMI • Electromagnetic interference (EMI) • There are two main types of EMI — conducted EMI and radiated EMI. • Conducted EMI goes through conductors, such as wires or power lines, while radiated EMI travels through the air and does not require a conductor. • Both conducted and radiated EMI can impact the performance of electronic devices through impairment, degradation, malfunctioning or system failure.

  3. RFI is an acronym for radio frequency interference, refers to noise that falls on the radio frequency spectrum within the electromagnetic frequency spectrum. Meanwhile, EMIrefers to any frequency of electromagnetic noise. • In other words, RFI is a subset of EMI and includes only electromagnetic currents with a frequency between 3 kilohertz and 300 gigahertz. Just like EMI, RFI can be conducted or radiated and can cause a variety of problems with electronic devices.

  4. WHAT IS EMC? • EMC is Electromagnetic Compatibility. • EMC describes how a device functions or performs in an environment of electromagnetic noise. • EMC includes two factors: • EMC • TOLERANCE TO NOISE • (NOISEIMMUNITY) • HOW MUCH NOISE IT PRODUCES

  5. WHERE DOES EMI COMES FROM? Natural Causes Man-made EMI is most often the result of electronics or electrical circuits, but can also result from switching systems or changes in large currents. Man-made causes of EMI span both residential and industrial sectors, and some devices can also create interference between internal components. Man-Made Electrical Devices

  6. NATURAL CAUSES OF EMI Naturally occurring EMI can come from a variety of sources, including: Lightning Strikes Solar Flares Cosmic Noise Static Electricity

  7. Atmospheric electrical storms Solar magnetic storms Snowstorms Dust storms Natural Electromagnetic Interference can occur at anytime and have adverse impact on inadequately protected electrical devices. Natural EMI, such as electrical storms or solar flares , can harm military equipment or transportation technologies. The sun can cause disruptions to satellite transmissions if it appears directly behind a satellite and the electromagnetic noise masks the satellite's transmission. On a smaller scale, naturally occurring EMI like snowstorms may cause radio static or disrupt cell phone signals.

  8. RESIDENTIAL CAUSES OF EMI (MAN-MADE) • Microwaves • Heating pads • Toaster ovens • Electric blankets • Heaters • Cell phones • Laptops • Wi-Fi devices • Bluetooth devices • Baby monitors Residential causes of EMI often come from devices that operate using a wireless signal, but also emanate from a variety of other electronic appliances.

  9. MAN-MADE INDUSTRIAL CAUSES OF EMI Industrial causes of EMI are often larger-scale and can cause severe damage to important technologies. Some common EMI sources in the industrial sector are as follows: • Electric motors and generators • Television transmissions • Cellular networks and telephone transmissions • Radioandsatellite • Grid power

  10. WHAT IS AN EMI FILTER? An EMI filter is a passive electrical device consisting of capacitors and inductors arranged in a specific circuit to suppress high frequency noise propagating along equipment and facility power lines. EMI is primarily manifested as harmonic energy/noise generated by sharp changes in circuit currents/voltages. What does an EMI filter do? When attached to circuits or devices, it can suppress electromagnetic noise transmitted through conduction. These filters extract any unwanted current conducted through wiring or cables, while allowing desirable currents to flow freely. How do EMI filters work? Most electromagnetic noise is in a higher frequency range, so EMI filters are often low-pass filters that sift out high frequencies while letting lower frequencies pass through. Different EMI line filters suppress specific frequencies of noise, while allowing others to flow unimpeded.
