5-CN4490-1S

RFI and EMI - Shielding and Absorbing Materials has been used in various applications across a wide range of industries. One such application is the 5-CN4490-1S, which is a multi-layer shielding material used to absorb and attenuate both receiving and transmitting electromagnetic interference (EMI). This shielding material is intended for use in applications where electromagnetic shielding, filtering, and control is essential, such as in aircraft, radar, communications and security systems.The working principle of the 5-CN4490-1S is based on the concept of attenuation of an incident electromagnetic field. This is done through the combination of two key elements – the shield material and the absorber material. The shield material serves as the outer layer of the shielding system, blocking the incident electromagnetic field from penetrating into the system. The absorber material is the inner layer, designed to absorb the electromagnetic energy that is not blocked by the shield material. The combination of these two components results in effective EMI shielding, allowing only a minimal amount of noise and interference to reach the device.The 5-CN4490-1S is suitable for both receiving and transmitting electromagnetic interference shielding purposes. It can be applied in a wide range of applications, including those in aircraft, radar, communication, military and security systems. The standard design consists of an outer shield layer and an inner absorbent layer, both containing uniform conductor spirals. The absorber layer is used to absorb the incident time-varying electric and magnetic fields. This layer is usually made of properly mixed or “meandered” PMM (Permanent Magnetic Material) components, which are then adhered between two thin wall copper shields.The construction and working principle of the 5-CN4490-1S enable it to provide come certain advantages, such as greater shielding effectiveness, convenience in manual mounting or installation, and compatibility with most types of systems. In addition, the material has excellent vibration resistance, airtightness, and chemical resistance. Any imperfections that may occur during the production and development process can be identified and corrected easily. Furthermore, the material is able to provide shielding solutions for both narrowband and broadband applications.In general, the 5-CN4490-1S provides a cost-effective solution for applications requiring effective EMI shielding and attenuation. The shielding material can be used to effectively reduce the amount of noise and interference that might otherwise affect the performance of sensitive equipment. Its features, including compatibility with most systems, ease of installation, and superior shielding effectiveness, make it an ideal choice for many different kinds of applications.
