Noise suppression sheet
for near-field high performance low frequency(300MHz-1GHz)

Model No. ema04
Noise suppression sheet is used for preventing oscillation in laptop PCs / mobile phones etc. and EMC countermeasures. By putting this sheet on areas where the problems are occuring, you can improve them.
Compared with other standard products, it has 2-3 times higher ability

High performance noise suppression characteristics are achieved by utilizing the anisotropic characteristics of graphite and by matching the spatial impedance.

The Characteristics of this noise suppression sheet are shown in figure below.
The higher the line is, the better the characteristics.

This product has more than twice the performance of standard products, and especially more than three times the performance from 300MHz to 1GHz.

Evaluation method of noise suppression sheet is standardized by IEC in May, 2006.
