DESCRIPTION
The BB147 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 gliding matching and a
direct matching assembly procedure.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
