Fusing
After fusing the final resistance value will be 50 times the
initial value.
Packaging
All resistors are supplied tape packed ready for loading on
to automatic sequencing and insertion machines.
The standard taping method and critical dimensions are
shown in figure 1. Component wire will not protrude
beyond the outside edge of the tapes.
Lead Formed resistors can also be supplied. Standard
options of Lancet, Radial and Goalpost forming are shown
in Lead Form Information section.
A detailed Packaging Data Sheet is available on request.
