Outline shown is case U, pin out is the same for all
cases. Also available: flanged – leads bent down (case
V); tabbed – leads bent up (case W), short leads (case
Y), and leads bent down (case Z). See Figures 55
through 60 for dimensions.

For exact specifications for an SMD product, refer to the SMD drawing. In
the SMD number the “X” in the “HXC” suffix corresponds to case U, case
V=U, case W=T, case Y=Y, and case Z=Z. SMDs can be downloaded
