Procurement Notes
Verify component authenticity through authorized distribution channels to ensure compliance with RoHS standards. Confirm that the ordering suffix matches the required package marking and lead-free specifications. Review the datasheet for absolute maximum ratings to prevent damage during handling or assembly processes.
Selection Notes
Select this component when a smaller capacitance value is required compared to other members of the SMV121x family. The SOT-23 package offers a standard footprint suitable for surface mount assembly. Ensure the circuit design accommodates the specific series resistance and parasitic inductance characteristics defined in the electrical specifications table.
Part Context
This part belongs to the SMV121x series of silicon hyperabrupt junction varactors. The series includes variants such as the SMV1213 and SMV1214, which differ primarily in their capacitance values and package options like SC-79 and SOD-882. All devices share similar operating temperature ranges and reliability standards.
