Important! Always connect the sense pins. If they
are not connected to a remote load, wire each
sense pin to its respective voltage output at the
converter pins.
The 0.145-inch pin length is shown. Please refer to
the part number structure for alternate pin lengths.

Please note that some competitive units may use
different pin numbering or alternate outline views;
however, all units are plugin-compatible.
It is recommended that no parts be placed beneath
the converter
