Packaging
Figure 2
The standard method of packaging GC resistors is taped in
ammo packs. Taped resistors on reel or loose packed
components can also be supplied by special request. In the
case of tape packed components the usable lead length is
reduced by the width of the tape. A detailed taping
specification is available on request.
c
These products are also available in a range of lead forming options.
In particular, GC65 & GC70 are available in ZI-form SMD format packed
in blister tape - see:
