2 Solving Electromagnetic Interference (EMI) with Ferrites What are ferrites? How do ferrites help Suppress EMI? How to chose proper ferrite and component Material Characteristics Material and Core Selection Frequency, bias, turns, temperature, size Cable cores and PCB level components 1

3 What Is A Ferrite? Ferrite is a ceramic material formed by reacting metal oxides into a magnetic material. - Soft magnetic material is one that can be both easily magnetized and demagnetized, so that it can store or transfer magnetic energy in alternating or other changing wave forms CHEMICAL COMPOSITION (metal oxides) + (iron oxide) (MnO + ZnO) (NiO + ZnO) (MgO + ZnO) + (Fe2O3) = + (Fe2O3) = + (Fe2O3) = Manganese - Zinc Nickel - Zinc Magnesium - Zinc 2

4 Definitions EMI Electromagnetic Interference Electromagnetic emissions from a device or system that interfere with the normal operation of another device or system. EMC Electromagnetic Compatibility The ability of a device or system to function without error in its intended electromagnetic environment. 3

5 EMI Suppression Sources of EMI Digital System Clock Pulses SMPS Oscillators Medical Equipment Microwave Equipment Radio & TV Frequency Converters Electronic Ballasts Switch Gear (contractors, relays) Household Appliances Power Supplies and Battery Chargers Motor Commutation Ignition Systems Victims (Susceptible) Radio & TV Receivers Modems Engine Control Modules Data transmission systems Medical Equipment Computer

6 Properties of Ferrites EMI Suppression A frequency dependant impedance that provides attenuation Formulations optimized for frequency bands Ferrites absorb EMI energy - dissipate as small amount of heat Powder compaction allows for a multitude of shapes High permeability concentrates magnetic filed in core allowing for a dense overall package High resistivity provides electrical isolation between multiple lines and minimizes eddy current losses 5

7 How Ferrites Are Used To Reduce Noise Noise Source Path Load (victim) Attenuation = 20 log 10 (Z s +Z sc + Z L ) Z s Z sc Z L (Z s + Z L ) db Z s Z sc Z L = Source impedance = Suppressor Core impedance = Load impedance 6

12 Common-Mode vs Differential-Mode Common-Mode Currents Noise Currents in phase (same direction) in the conductor pair. Usually found where radiated noise attaches itself to the conductor. Differential-Mode Currents Can be Functional (desired) currents or Noise currents or combination of both. 11

13 Common-Mode Choke I D I D Differential Mode (functional) Currents Fluxes cancel * no inductance (impedance) * no effect on currents * core will not saturate with high I D currents Common Mode Currents I C I C Fluxes Add * inductance (impedance) in series with conductor * effectively blocking Common Mode currents 12

14 Differential Mode Application Ferrite Bead Provide selective attenuation of high frequency signals and not effect lower freq functional current Affects both Differential and Common Mode signals D C Core can saturate at high levels of (low frequency) current 13
