L = Length. B = Width. D = Thickness. C = Width of wrap around (in mm)
Packaging:
Bulk in plastic bags or tubes – minimum quantity 100 pieces per value
Blistertape acc. to IEC 60286-3 – minimum 1000 pieces per value
Reel diameter 180 mm or 330 mm
Ordering Data:
Type – value – tolerance – TCR – packaging
Example: CRW 1216 100 R ± 1 % TK50 Tape 180 mm
If no requirements for TCR and taping are given, the standard value (highest value in
table) will be supplied and packaging is bulk
