Packaging

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.

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:
