Test Frequency: 100kHz Class of Magnetic Shield: Magnetic shield of magnetic powder in resinOperating Temperature Range (Self-temperature rise is not included): -40 to +85 COnly for reflow soldering.*1 When Rated Current is applied to the Products, Inductance will be within 30% of nominal Inductance value.*2 When Rated Current is applied to the Products, self-generation of heat will rise to 40 C or less.

(Based on Inductance Change)When Rated Current is applied to the Products,

Inductance will be within +-30% of nominalInductance value. (Based on Temperature Rise)When Rated Current is applied to the Products,self-generation of heat will rise to 40 C or less.

! Caution (Rating)Do not use products beyond the rated current asthis may create excessive heat.

NoticeSolderability of Tin plating termination chip might bedeteriorated when low temperature soldering profilewhere peak solder temperature is below the Tin meltingpoint is used. Please confirm the solderability of Tinplating termination chip before use.
