Mounting Information
The
illustration
indicates
the
recommended
mounting pad configuration for the SC-79, SC70
3LD
and
SOD-323
packages.
Solder
paste
containing flux should be screened onto the pads to
a thickness of 0.005- 0.007 inches. The plastic
package is placed in position, firmly adhering to the
solder paste.
Permanent attachment is performed by a reflow
soldering
procedure
during
which
the
tab
temperature does not exceed +275 °C and the body
temperature does not exceed +250 °C, for standard
models and +260 °C for the RoHS compliant
devices.
These varactors are available in the three case
styles shown. When ordering, specify the desired
case style by adding the case designation (287 for
SOT-23, 1146 for SC70 3LD, 1141 for SOD-323) as
a suffix to the model number. For example,
MA4ST230-1141 specifies the MA4ST230 varactor
in the SOD-323 package. The model number
indicated is for a single varactor. Common cathode
pairs are available in SOT-23 package, and are
specified by adding “CK” to the end of the model
number. For example MA4ST230CK-287 specifies
the MA4ST230 varactor in common cathode pairs.
For RoHS Compliant Parts, use the Following
Suffices for the Given Package Style
( After the Base P/N ) :
SC-79 : 12790T
SOD-323 : 11410T
SC70 3LD : 1146FT
As example, the RoHS P/N for the Base P/N
MA4VR-000230 in SOD-323 is :
MAVR-000230-1146FT.
Please refer to Application Note M538 for surface
mounting instructions.
