Note:
The high pulse/surge capability of the OARS parts is attributed
to the solid metal alloy construction. In many applications the
cross-section of the OARS is greater than the cross-section of
the board traces connecting the parts to the circuit board.
Cross-Sectional area ranges from approximately 780 mils to
3600 mils.
