Note
• Pulse capability increases based on the amount of wire for the resistance value and construction. The WSC0002 has greater pulse capability
than WSC4527 due to differences in internal construction. The non-inductive WSN has greater pulse capability for the same size WSC
because the second layer of wire increases the wire mass available to withstand pulse energy without exceeding temperature limits.
