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).
