c !Caution/Notice
!Caution (Rating)
Do not use products beyond the rated current as
this may create excessive heat and deteriorate
the insulation resistance.
Notice
Solderability of Tin plating termination chip might be
deteriorated when low temperature soldering profi le
where peak solder temperature is below the Tin melting
point is used. Please confi rm the solderability of Tin
plating termination chip before use.
