Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer verification. Confirm that the specific ordering suffix matches the required package and tape-and-reel specifications. Ensure compliance with RoHS directives and check for any end-of-life notifications prior to final procurement decisions.

Selection Notes

Select this component when a high tuning ratio is required within a 30 V reverse voltage limit. The SCD-80 package is suitable for automated surface-mount assembly processes. Evaluate the 2.75 pF baseline capacitance against circuit requirements to ensure proper frequency coverage without excessive parasitic loading.

Part Context

This part belongs to the BB664 family of varactor diodes from Infineon Technologies. The family provides various capacitance ratios and package options for RF applications. The BB 664 E7902 specifically utilizes the SCD-80 footprint, distinguishing it from other variants in the series that may use different housing styles.

Replacement Considerations

Check for BB664H7902XTSA1 as a related variant within the same product family. Verify pinout compatibility and exact capacitance tolerances before substituting. Ensure the replacement maintains the required 30 V rating and SCD-80 package dimensions.
