Features
Silicon epitaxial planar capacitance diodes with very wide effective capacitance
variation for tuning the whole range of UHF television bands.
Two BB721/BB721S tuner diodes in series are used for direct satellite receivers.
These diodes are available as singles or as matched sets of two or more units
according to the tracking condition described in the table of characteristics.
