DESCRIPTION
The BB134 is a variable capacitance
diode fabricated in planar technology, and
encapsulated in the SOD323 very small
plastic SMD package.
The excellent matching performance is
achieved by a direct matching assembly
procedure. The unmatched type, BB135
has the same specification.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
