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 650

mils to 3600 mils.
