Alternative pinout.
Option M
Surface mount version.
This option defines an alternative pinout.
Option K excludes option M and vice versa.
Note: Precautions should be taken when reflow soldering
the SMD version, option M. The reflow soldering instruc-
tions below should be strictly adhered to. An inadequate

Infrared soldering is not permitted.
The surface mountable version of this product is assem-
bled with high melting point solder (227 C) to ensure that
the solder joints of of the internal components do not de-
grade in the end users SMD soldering process.
This product is only specified for "Forced Convection
Reflow Soldering" (Hot Air). Any conventional soldering
profile is acceptable provided that the restriction curve be-
low is not exceeded at any time during the reflow process.
