Note: 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.
CAUTION: 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. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.

Electrical and Mechanical Specifications
The absolute maximum ratings of the SMV1247-040LF and
SMV1249-040LF varactor diodes are provided in Table 1.
Electrical specifications are provided in Table 2. Typical
capacitance values are listed in Table 3.
Typical performance characteristics of the SMV1247-040LF and
SMV1249-040LF varactor diodes are illustrated in Figures 1
and 2.
Package Dimensions
The PCB layout footprint for the SMV1247-040LF and SMV1249-
040LF varactor diodes is provided in Figure 3. Typical case
markings are shown in Figure 4. Package dimensions are
provided in Figure 5. Tape and reel dimensions are provided in
Figure 6.
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 SMV1247-040LF and SMV1249-040LF varactor diodes 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 these products, whether it is
done manually or in a production solder reflow environment.
Production quantities of these products are shipped in a standard
tape and reel format.
