Do I need EMI Sheilding?

1st Dec 2021

EMI Shielding is used in a wide range of applications and the EMI Shielding market is forecast to grow at an annual rate of 5.5% between 2018 and 2024.

What is Electromagnetic Interference (EMI)?

First, let’s take a look at what Electromagnetic Interference (EMI) is and how it affects your application. Electromagnetic interference (EMI), also called radio-frequency interference (RFI), is a disturbance generated by an external source that affects a circuit. This disturbance can disrupt the performance of electronics devices, equipment, and systems that are critical in industries like RAIL, Aerospace, Defense and Transportation, among others. The changes in electrical currents and voltages that can cause EMI can be both natural and man-made, including ignition systems and cellular networks used for mobile phones.

How do I protect against Electromagnetic Interference (EMI)?

To protect against these Electromagnetic Interferences a variety of products can be used, including EMI/RFI Shielding for cable assemblies. This wrap-around sleeving is designed for high-performance EMI shielding of wire and cable bundles. The self-wrapping feature also allows for quick and easy installation and removal during repair.

What EMI product is best for my application?

The type of EMI shielding needed is dependent on the application it will be used in. Roundit EMI FMJ Space is often used in aeronautical, space and military industries, while Roundit V0 EMI is used primarily in RAIL, marine and electronics industries. Knowing your requirements and getting to know your options will help you make an informative decision on the type of EMI Shielding needed.
