N.B. This product can be custom built to meet specific voltage coefficient or pulse requirements. 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 c 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. f f 1 2 In particular, GC65 & GC70 are available in ZI-form SMD format packed 6 b 6 in blister tape - see:
