BB639/BB659...
Silicon Variable Capacitance Diodes
•
For tuning of extended frequency band
in VHF TV / VTR tuners
•
High capacitance ratio
•
Low series inductance
•
Low series resistance
•
Excellent uniformity and matching due to
"in-line" matching assembly procedure
•
Pb-free (RoHS compliant) package
