PCB Warping
PCB should be designed so that products are not
subjected to the mechanical stress caused by warping
the board.
• Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.
• This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please review our product specifications or consult the approval sheet for product specifications before ordering.

Soldering and Mounting
Products should be located in the sideways direction
(Length: a<b) to the mechanical stress.
Poor example
Do not use gild pattern; excess soldering heat may dissolve
metal of a copper wire.
