Introduction to RFI and EMI - Shielding and Absorbing Materials

Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) can cause numerous problems in electronic communications systems. RFI and EMI can interfere with radio signals, disrupt television reception, interfere with data transmission, and corrupt stored data. As a result, shielding and absorbing materials are designed to attenuate, absorb, and direct these energies away from sensitive electronic systems.

Types of Shielding and Absorbing Materials

The two main categories of shielding and absorbing materials are metallic and non-metallic. Metallic materials, such as copper, aluminum, and tin, are used for the physical conductive barriers required to shield electronic components from RFI and EMI. Non-metallic materials, such as dielectrics, ferrites, and carbon composite structures, are typically used for absorbing EMI inside an electronic system.

5-CN3190-1/2S Application Field and Working Principle

The 5-CN3190-1/2S is a non-metallic type of shielding and absorbing material which is manufactured by Crystal Novations Ltd. It is a thermoplastic elastomer material that possesses electrical characteristics when used in an electromagnetic environment.The 5-CN3190-1/2S is designed to provide shielding and absorbing protection from environmental radiation in the frequency range from 2 Hz to several GHz. What sets it apart from other materials is its ability to combine dielectric loss with mechanical dampening to provide both shielding and absorbing characteristics at the same time. For mechanical dampening, the 5-CN3190-1/2S has a Shore A hardness of 70, providing an effective shock absorption over a wide range of temperatures. The material can be used in a wide variety of applications, from automotive to telecommunications, including medical imaging, MIL-SPEC, and EMI/RFI shielding.The material works by acting as an electromagnetic wave guide. It is designed to allow EMI/RFI radiation to enter and then dissipate energy into adjacent media or mechanical dampening layers. The material can also be manipulated to optimize waveguide properties by manipulating its specific geometry.This type of shielding and absorbing material is especially useful in applications where dampening combined with EMI/RFI shielding is required. This is why the 5-CN3190-1/2S has become one of the most sought-after materials in the EMI/RFI shielding market. The material also complies with all relevant safety and performance standards, making it a safe and reliable choice.
