Taping (leaded varistors)
All leaded varistors are available on tape.
Exception: S10K510 … K680, S14K510 … K1000, S20K385 … K1000.
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 ordering tables on page 213 ff list disk types available on tape in detail, i. e. with complete type
designation and ordering code. Taping mode and, if relevant, crimp style and lead spacing are cod-
ed in the type designation. For types not listed please contact EPCOS. Upon request parts with lead
spacing
= 5 mm are available in Ammopack too.

Taping modes/reel types
Taped varistors have the letter “G” appended to the type designation.
The different tapes and matching reel types are identified by numbers as shown in the table on
page 208.
Types with lead spacing
= 5, reel diameter 360 mm, have the code letter “G” while types with
lead spacing
= 7,5 and 10 on 500-mm reels are identified by “G5”.
Furthermore types with lead spacing
= 5 are available in Ammopack, code letters “GA”.
Versions G2, G3 and G4 are special tapes on 360-mm reels resp. Ammopack: G2 denotes the seat-
ing plane height
H
0
= 18 for crimped versions. Tapes G3 and G4 are available on 360-mm reels in
case the 500-mm reels are too big for your insertion machine.
Crimp styles
Both crimped and straight leads are standard for taped disk varistors. The leads are differently
crimped for technical reasons; the individual crimp styles are denoted by consecutive numbers
(S, S2 … S5) as shown in the dimensional drawings on page 212.
The crimp styles of the individual types can be seen from the type designation in the ordering tables.
Example straight leads:
