Performance Data

Packaging

All PR resistors are supplied tape packed ready for loading on

to automatic sequencing and insertion machines.

Component wires will not protrude beyond the outside edge

of the tapes.

Alternative packaging available by request.

Lead formed resistors can also be supplied. Standard options

of Lancet, Radial and Goalpost forming are available.
