Dep ending on its magnetic permeability, a particular ferrite material will be effective in a certain frequency band. A schematic representation of the relationship between the magnetic permeability of each material and the corresponding effective band range is shown in Figure 1. Materials with higher magnetic permeability are effective in the lower frequency range, while those with lower magnetic permeability are effective in the higher frequency range. Thus, Mn-Zn products are mainly used for reducing conduction noise, while Ni-Zn products are commonly used for radiation noise countermeasures. The effective frequency range varies depending on core shape, size and number of windings. This frequency dependence of the magne tic perme ability as shown in the figure serve s for refer ence purpos es only and it shoul d be teste d on the actua l device t o determine its effectiveness. S18H, S15H, 10H, 7H, 5H, 1400L and 700L are KEMET’s proprietary ferrite material names. Other materials can also be available on request.

While the chokes themselves are quite robust in other environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long term storage. KEMET recom mends that maxim um stora ge tempe rature not excee d 40°C and maxim um stora ge humidi ty not excee d 70% relati ve humidi ty and atmosph eres shoul d be free of chlori ne and sulfu r beari ng compo unds. Tempe rature fluctu ations should be minimiz ed to avoid conde nsation on the parts . Avoid also stora ge near strong magne tic fields as this might magnet ize the product. For optimized solderability, AC Line Filters’ stock should be used promptly, preferably within 6 months of receipt. Product temperature rise values The values listed for tempreature rise are the result of self-heating in wires when the rated current (commercial frequency) is applied. Check and evaluate the value of the core temperature rise under actual operating conditions when using. Export Control For customers in Japan For products that are controlled items subject to the “Foreign Exchange and Foreign Trade Law” of Japan, the export license specified by the law is requi red for expor For customers outside Japan AC Line Filters should not be used or sold for the use in the development, production, stockpiling or utilization of any conventional weapons, mass-destruction weapons (nuclear, chemical, biological weapons or missiles) or any other weapons.
