* Y2/X1 (B16 and M16) 2220 parts with values >5.6nF have a maximum thickness of 4.5mm.
** X2 (B17) 2220 parts with values >10nF have a maximum thickness of 4.0mm.
†M16 parts have an open mode construction to reduce the risk of short-circuit failure in the
event of a mechanical crack developing. For further information on the design of open mode
parts, refer to page 35 of this catalog.
