Notice (Rating) In operating temperatures exceeding +85D, derating of Derating current is necessary for chip Ferrite Beads for which rated current is 1500mA or over. Please apply the derating curve shown in chart according to the operating temperature. 6A 6 5 4A 4 3A 3 2.5A 2A 2 1.5A 1.4A 1.2A 1 1A 0 85 125 Operating Temperature D Impedance-Frequency Characteristics BLM41PF800SN1 100 Z 75 R 50 X 25 0 1 10 100 1000 Frequency (MHz) Caution/Notice Caution (Rating) Notice Do not use products beyond the rated current and Solderability of Tin plating termination chip might be rated voltage as this may create excessive heat deteriorated when low temperature soldering profile and deteriorate the insulation resistance. where peak solder temperature is below the Tin melting point is used. Please confirm the solderability of Tin plating termination chip before use. o This data sheet is applied for CHIP FERRITE BEAD used for General Electronics equipment for your design. Note: 1.
