Taping and packaging of leaded varistors
Tape packaging for lead spacing
= 5 fully conforms to IEC 60286-2, while for lead spacings
= 7.5 and 10 the taping mode is based on this standard.
The overview of delivery mode on pages 11 ff lists disk types available on tape in detail, i.e. with
complete ordering code and type designation. Taping mode and, if relevant, crimp style and lead
spacing are coded in the type designation. For types not listed please contact EPCOS. Upon re-
quest parts with lead spacing
= 5 mm are also available in Ammo pack too.
