EMI Absorbers Detail
With the demand for faster speeds in more compact products, engineers have come to face new and more EMI (Electromagnetic Interference) related problems. Excessive EMI will not only decrease the performance of components but can also possibly emit harmful waves.
To ensure quality control the FCC and other government agencies have imposed more EMC requirements to pass for those designing products. As a result EMI solutions have become more critical than ever.
KITAGAWA INDUSTRIES America, Inc.’s EMI absorber materials can be life-saving solutions that can be applied when there is no time to do major redesigning of the board layout. These non-conductive materials that consist of metallic particles, ferrite material, and silicone gather magnetic field and convert EMI noise into negligible heat energy. They work effectively at various frequency ranges from the KHz and MHz range up to the higher GHz range. With non-conductive adhesive on one side, they can be easily applied directly over ICs, CPUs, graphic chips, and even cables without fear of short-circuiting. These flexible sheets come in a variety of different thicknesses to fit any application’s space restrictions.
- Easy to installation. …etc from presentation materials
- Applications: Smart phones, Cell phones, Tablet PCs, Laptops, ultra-thin type laptops
- RoHS Compliant
These absorber sheets can also serve other uses. Coupling and cross talk are major problems in applications where many components have to share extremely limited space. Adding EMI absorbers can reduce these two problems while also adhering to space restrictions. Absorber sheets have also been used to increase the performance in RFID applications by correcting the magnetic field loop for RFID reader malfunctions at 13.56 MHz. This material gathers magnetic field to gain more signals in order to eliminate the need for wires. They come in a variety of types depending on the attenuation needed and application including those devices with near field communication (NFC) technology.
