Ceramic Feedthrough Filters: Winning the Finite EMI Fight

In today’s world nearly all electronic devices have wireless connectivity features built into them. From laptop computers to home security systems, these devices rely on transmitting and receiving Radio Frequency (RF) or Microwave signals from one device to another. The term used to identify the energy in these transmissions is Electro-Magnetic Radiation. Electro-Magnetic Radiation is around us everywhere, all the time. The frequencies that this radiation falls into is in the 3 KHz to 300 GHz range.
