* 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 .

** For suffix “V” (Extremely High Energy Type) add 0 .1 (0 .004) to “E Max .”
