Product Overview

The BB644/BB664 series are silicon variable capacitance diodes designed for VHF TV-tuners. These diodes offer a high capacitance ratio, low series inductance, and low series resistance. Their excellent uniformity and matching are achieved through an "in-line" matching assembly procedure. The components are Pb-free and RoHS compliant.
