Product Description

Product Overview

The 2SC3585 is an ultra-high frequency, low-noise NPN silicon epitaxial bipolar transistor manufactured using a planar process. It offers high power gain, a low noise figure, a wide dynamic range, and ideal current characteristics. Packaged in a surface-mount SOT-23-3L, this transistor is primarily used in VHF, UHF, and CATV high-frequency broadband low-noise amplifiers.
