Absorb Radiation with Molex HOZOX EMI Absorption Sheets and Tape

May14_MouserMouser Electronics, Inc. is now shipping the HOZOX EMI absorption sheets and tape manufactured by Molex. While 0.1 mm thick, these flexible sheets suppress most unwanted electromagnetic interference (EMI) while meeting government EMC regulations worldwide. The unique dual-layer structure of the HOZOX allows the sheeting to efficiently absorb both megahertz and gigahertz electromagnetic energy, providing a wide range of EMI protection for a variety of applications.

The Molex HOZOX EMI absorption sheets provide improved EMI noise reduction for many electronics systems. Electromagnetic interference can interfere with the proper operation of many electronic systems by inducing electric currents into wiring and PC board traces, resulting in difficult to diagnose equipment malfunctions. In addition, EMI can cause self-heating in magnetically conductive metals, resulting in overheating problems that can result in equipment failure from thermal damage to components.

The HOZOX EMI absorption sheets inhibit stray EMI by using a unique two-layer design. The magnetic layer is composed of a sendust powder that efficiently absorbs low frequency electromagnetic noise. The much thinner conductive layer is composed of ferrite powder mixed with nano-carbon wires that mitigate high-frequency electromagnetic energy. Together these dual layers provide excellent EMI protection over a broad range of frequencies. A layer of adhesive is applied to the conductive layer and allows the sheets to be pressed firmly into place. Optionally, the adhesive can be applied to the magnetic layer. Once properly applied, the sheeting keeps stray electromagnetic fields safely contained.

These sheets are well suited for compact electronic devices such as medical equipment, Wi-Fi and other RF modules, power supplies, and low power consumer electronics.

The HOZOX is available both in sheets, or in 10 or 20mm tape. To learn more, visit
