EMI and Consumer Products

Electromagnetic interference (EMI) is considered a disturbance that is generated by external forces and negatively affects electrical circuitry (electromagnetic induction, conduction, and electrostatic coupling). Disturbances degrade circuit performance, and in certain cases can even stop devices from functioning. In the modern world, electronic devices are found everywhere. They are in cars, in homes, in offices, and even in subway cars. To ensure the proper functioning of personal and commercial electronics, EMI and RFI shielding are needed. In 1982, the FCC passed public law 97-259 to adequately regulate susceptibility of electronic equipment.  Many countries across the globe have strict legal requirements mandating electromagnetic compatibility. Without these strict regulations, it is possible we would see more plane, car, and train, and medical accidents.

EMI shielding

Sources of EMI and RFI come from human-made and natural sources, although human-made EMI amounts for a substantial amount of the problem. Some of the most common causes of RFI and EMI include:

  • Transmitters
  • Toaster ovens
  • Doorbell transformers
  • Ultrasonic pest control systems
  • Electric blankets
  • Touch controlled lamps
  • Electric bug zappers

EMI shielding

Television and CRT monitors that are located too close to each other can cause a shimmy effect on all screens in the vicinity. RFI and EMI shielding would help negate this affect. Wireless and Bluetooth devices suffer from EMI when above 2.4 GHZ.

Regardless of your device and its application, our team is ready to help design custom EMI shielding and RFI shielding that meets your exact needs. Protecting electronic circuits from excess EMI is essential for products to run correctly.
