Schaffner Electromagnetic Interference

EMI Filters

Electromagnetic Interference

EMI is defined as any conducted radiated or magnetically induced voltage which degrades, obstructs, or repeatedly interrupts the desired performance of electronic equipment. There are four fundamental interference sources:

  • Man made noise
  • Electromagnetic pulses through nuclear reactions (NEMP, EMP)
  • Electrostatic discharge
  • Cosmic noise

It is sometimes referred to as audio hum, crosstalk, degenerative feedback, electrical noise and RFI – radio frequency interferenc
