Do not use products beyond the rated current as this may create excessive heat and deteriorate the insulation resistance. 2. Be sure to provide an appropriate fail-safe function on your product to prevent a second damage that may be caused by the abnormal function or the failure our product. Notice Solderability of Tin plating termination chip might be deteriorated when low temperature soldering profile where peak solder temperature is below the Tin melting point is used. Please confirm the solderability of Tin plating termination chip before use. oThis data sheet is applied for CHIP FERRITE BEAD used for Automotive Electronics equipment for your design. !Note: 1.
