PACKAGING RULES
Waffle Pack
Can be filled up to maximum quantity indicated in the table
here above, taking into account the minimum order quantity.
When quantity ordered exceeds maximum quantity of a
single waffle pack, the waffle packs are stacked up on the top
of each other and closed by one single cover.
To get “not stacked up” waffle pack in case of ordered
quantity > maximum number of pieces per package:
Please concult Vishay/Sfernice for specific ordering
code
Tape and Reel
Can be filled up to maximum quantity indicated in the table
here above, taking into account the minimum order quantity.
When quantity ordered is between the MOQ and the
maximum reel capacity, only one reel is provided.
When several reels are needed for ordered quantity
within MOQ and maximum reel capacity: Please concult
Vishay/Sfernice for specific ordering code
