Outline： Recently, telecommunication and electronic equipments require faster communication, larger information capacitance and smaller equipment size. The generation of electromagnetic noises are accordingly increased. Thus the solution for electromagnetic noise problems of the equipment became an urgent task to solve for circuit designers and EMC/EMI workers. The new CNS and CNF series developed based on accumulated technologies of magnetic materials can eliminate noises effectively.You can solve EMC/EMI problems by attaching CNS and CNF materials simply on the parts of noise sources. CRF Series with high permeability at 13.56MHz concentrates an electromagnetic wave and prevents interference between loop antenna and metal part. Because of these characteristics, communication distance between antenna and RF-ID reader is effectively increased. Concept of Absorber： In contrast with conductive shielding materials,the reflection of incident waves is very low,because electromagnetic energy absorbed is changed to heat.
