* Bulk parts for 320VAC and larger come standard with inline crimp (as referenced at beginning of “Standard Dimensions and Lead Modification
Options” section ) for straight disk seating on PC boards. Therefore, “a” dimension is not applicable. If 320VAC and larger size are required without
in-line crimp, please reference “Part Number System” position # (8) and add “N” and reference “a” dimensions (for off-set) above.
