<strong>EMI</strong> <strong>Filters</strong> <strong>for</strong> the SJ300/L300P<br />
NF-<strong>CE</strong>H Series<br />
The following describes the components <strong>Hitachi</strong> offers to meet <strong>CE</strong> <strong>EMI</strong> requirements, Class A and<br />
Class B. The NF-<strong>CE</strong>H <strong>Filters</strong> provide <strong>EMI</strong> attenuation to meet Class A. The addition of the FC-H<br />
Ferrite will provide attenuation sufficient to meet Class B. If you have further questions, please<br />
contact <strong>Hitachi</strong> or your Authorized Sales Representative.<br />
