Working Principles

The 650R-07LF is an NPN transistor that operates based on the principles of bipolar junction transistors (BJTs). It consists of three layers: the emitter, base, and collector. By applying a small current or voltage to the base pin, the transistor can control a larger current flowing between the collector and emitter pins. This allows for signal amplification in electronic circuits.
