Electrical and Mechanical Specifications
The absolute maximum ratings of the SMV1247-SMV1255 group
of varactors are provided in Table 2. Electrical specifications are
provided in Table 3. Typical capacitance values are listed in
Table 4. Typical performance characteristics of the
SMV1247-SMV1255 varactors are illustrated in Figures 1
through 4.
The SPICE model for the SMV1247-SMV1255 varactors is shown
in Figure 5, and the associated model parameters are provided in
Table 5.
Package dimensions are shown in Figures 6 to 12 (even
numbers), and tape and reel dimensions are provided in Figures 7
to 13 (odd numbers).
Package and Handling Information
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The SMV1247-SMV1255 group of varactors are rated to Moisture
Sensitivity Level 1 (MSL1) at 260 C. They can be used for lead or
lead-free soldering. For additional information, refer to the
Skyworks Application Note, Solder Reflow Information, document
number 200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set
at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.
This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.
