Consequently the impedance at 1 GHz is up to 3 times higher. &lt;/span&gt;&lt;/li&gt;&lt;li&gt;&lt;span style="font-size:12pt;"&gt;Application e.g. HDD, fast bus signals&lt;/span&gt;&lt;/li&gt;&lt;li&gt;&lt;span style="font-size:12pt;"&gt;High Current: &lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:12pt;"&gt;&amp;quot;High Current&amp;quot; SMD ferrites &lt;span class="we-catalog-wordhighlight"&gt;WE&lt;/span&gt;-CBF are designed for high current (o&lt;span class="we-catalog-wordhighlight"&gt;ve&lt;/span&gt;r 1 A). The rated current refers to 40 K &lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:12pt;"&gt;self-heating.

Therefore they are &lt;/span&gt;&lt;span style="font-size:12pt;"&gt;wide band through the whole spectrum.&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:12pt;"&gt;Application e.g. control signals, RS232, RS422, DC/DC con&lt;span class="we-catalog-wordhighlight"&gt;ve&lt;/span&gt;rter&lt;/span&gt;&lt;/li&gt;&lt;li&gt;&lt;span style="font-size:12pt;"&gt;Advice:&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:12pt;"&gt; Pay attention for the use of SMD-Ferrites for high rated current &amp;gt;1 A and ambient temperature o&lt;span class="we-catalog-wordhighlight"&gt;ve&lt;/span&gt;r +85°C that the rated current has to be reduced when temperature is abo&lt;span class="we-catalog-wordhighlight"&gt;ve&lt;/span&gt; +85°C (Derating).&lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;&lt;p style="margin:0;"&gt;&lt;a class="jive-link-external-small" href="http://katalog.we-online.de/en/pbs/WE-CBF?m=t&amp;amp;sq=we+ve&amp;amp;sp=&amp;amp;sp=http%3A%2F%2Fwww.we-online.de%2Fweb%2Fen%2Fpassive_bauelemente_standard%2Fsearchpage_PBS.php%3Fsearch%3Dwe-ve#vs_t2:1_ct:3" rel="nofollow ugc noopener" target="_blank"&gt;&lt;br /&gt;&lt;/a&gt;&lt;/p&gt;&lt;table border="0" cellpadding="4" cellspacing="4" class="jiveBorder" style="width:100%;border:0px solid #000000;"&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td style="border:0px solid black;border:0px solid #000000;text-align:center;"&gt;&lt;span style="font-size:14pt;"&gt;&lt;a class="jive-link-external-small" href="http://katalog.we-online.de/en/pbs/WE-CBF?m=t&amp;amp;sq=we+ve&amp;amp;sp=&amp;amp;sp=http%3A%2F%2Fwww.we-online.de%2Fweb%2Fen%2Fpassive_bauelemente_standard%2Fsearchpage_PBS.php%3Fsearch%3Dwe-ve#vs_t2:1_ct:3" rel="nofollow ugc noopener" target="_blank"&gt;Würth Elektronik parts overview&lt;/a&gt;&lt;/span&gt;&lt;/td&gt;&lt;td style="border:0px solid black;border:0px solid #000000;text-align:center;"&gt;&lt;span style="font-size:14pt;"&gt;&lt;a class="jive-link-external-small" href="http://uk.farnell.com/jsp/search/browse.jsp?N=2031+203674&amp;amp;Ntk=gensearch&amp;amp;Ntt=742792&amp;amp;Ntx=mode+matchallpartial&amp;amp;No=0&amp;amp;getResults=true&amp;amp;appliedparametrics=true&amp;amp;locale=en_UK&amp;amp;divisionLocale=en_UK&amp;amp;catalogId=&amp;amp;skipManufacturer=false&amp;amp;skipParametricAttributeId=&amp;amp;prevNValues=2031+203674&amp;amp;filtersHidden=false&amp;amp;appliedHidden=false&amp;amp;autoApply=false&amp;amp;originalQueryURL=%2Fjsp%2Fsearch%2Fbrowse.jsp%3FN%3D2031%2B203674%26Ntk%3Dgensearch%26Ntt%3D742792%26Ntx%3Dmode%2Bmatchallpartial%26No%3D0%26getResults%3Dtrue%26appliedparametrics%3Dtrue%26locale%3Den_UK%26divisionLocale%3Den_UK%26catalogId%3D%26skipManufacturer%3Dfalse%26skipParametricAttributeId%3D%26prevNValues%3D2031%2B203674" target="_blank"&gt;Farnell parts overview&lt;/a&gt;&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;&lt;p style="margin:0;padding:0px;"&gt;&amp;nbsp;&lt;/p&gt;&lt;p style="margin:0;padding:0px;"&gt;&amp;nbsp;&lt;/p&gt;&lt;p style="margin:0;padding:0px;"&gt;&amp;nbsp;&lt;/p&gt;&lt;p style="margin:0;text-align:center;"&gt;&lt;span style="font-size:18pt;"&gt;-follow us on &lt;a class="jive-link-external-small" href="http://www.element14.com/community/groups/wuerth-elektronik" target="_blank"&gt;element14&lt;/a&gt;-&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;
