!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.
