(based on temperature rise) when rated current is applied to the products, self-generation of heat will rise to 40 c or less. notice (rated current) inductance-frequency characteristics (typ.) inductance-current characteristics (typ.) temperature rise characteristics (typ.) ! caution (rating) do not use products beyond the rated current as this may create excessive heat. 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. ! caution/notice
