FT122T-R

Product Overview

Category

FT122T-R belongs to the category of electronic components.

Use

It is primarily used for signal amplification and switching in electronic circuits.

Characteristics

  • Small size
  • High gain
  • Low power consumption
  • Wide operating voltage range

Package

FT122T-R is available in a compact package, suitable for surface mount technology (SMT).

Essence

The essence of FT122T-R lies in its ability to amplify weak signals and control the flow of current in electronic circuits.

Packaging/Quantity

FT122T-R is typically packaged in reels or tubes, with quantities varying based on customer requirements.

Specifications

  • Maximum Collector Current: 500mA
