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 MAVR-

000230 in SOD-323 is :

MAVR-000230-1146FT.

Please refer to Application Note M538 for surface

mounting instructions.
