Please also refer to the common precautions shown on page 4 of this catalog. 1. Use rosin-based flux or halogen-free flux. 2. For cleaning, use an alcohol-based cleaning agent. Before using any other type, consult with our sales person in advance. 3. Carefully handle EMI Bead Cores (hereafter called the bead cores) so as not to apply excessive mechanical stress to their bodies in order to avoid damaging them. 4. Store the bead cores in a location with a temperature ranging from -5 C to +40 C and a relative humidity of 40 % to 60 %, where there are no rapid changes in temperature or humidity. 5. Use the bead cores within a year after the date of the outgoing inspection indicated on the packages. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use. Should a safety concern arise regarding this product, please be sure to contact us immediately. - 272 - 00 Sep. 2010
