Outline shown is case U2, pin out is the same for all
side-leaded cases. Also available: flanged – leads bent
down (case V); tabbed – leads bent up (case W), short

For exact specifications for a DSCC product, refer to the
DSCC drawing. Contact your Interpoint representative for
status on the FME DSCC releases. See Section A3,
“SMD/DSCC Lists”, for more information.
*Case/Lead Option: See section B8, cases J4, U1, U2, V, W, Y, and Z for
drawings and dimensions, see Section A5 for ordering information.
FME models: Case U2 has no designator in the case/lead option position.
To designate a case option add the case letter to the model number –
FME28-461V.
FMD models: Case J4 (down-leaded) has no designator in the case/lead-
option position. To designate case U1 (side-leaded) for the FMD place
"SL" in the case/lead option position – FMD28-461SL. The 270 volt FMD
is only available in the side-leaded case – FMD270-461SL.
