2 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.
2.1 Taping in accordance with IEC 60286-2 for lead spacing 5.0 mm
2.2 Taping based on IEC 60286-2 for lead spacing 7.5 and 10 mm
