* For 10mm lead spacing use suffix “X” for bulk parts (18 and 20mm disc diameter).

Notes:
1.  Maximum epoxy extending on leads (measured from bottom most portion of disc) is 3mm for all disc sizes with exception of 20mm, 25mm and 32mm disc sizes which are 4mm.
2.  Reduced dimensions, special lead diameters and special lead spacing may be avaliable upon request.
3.  Bulk parts for 320VAC and larger come standard with inline crimp (as referenced above) for straight disc seating on PC boards. If 320VAC and larger size are required without in-line crimp, please reference “Part Number System” position # (8) and add “N” and reference “a” off-set dimensions.
4.  The maximum straight lead length avaliable for 5mm leadspacing is 40mm max, 7.5mm leadspacing is 32mm max, 10mm leadspacing is 35mm max.

* 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 disc seating on PC boards. Therefore, “a” dimension is not applicable. If 320VAC and larger size are required without inline crimp, please reference “Part Number System” position # (8) and add “N” and reference “a” dimensions (for off-set) above.

** These dimensions also apply to “E” Series (High Energy) parts. For suffix “V” (Extremely High Energy Type) add 0.1 (0.004) to “E Max.”
