The FMMT491 NPN Transistor SOT-23-3 manufactured by Shikues is a surface mount, three-pin discrete transistor with NPN polarity. It has an operating current of 1 amp at a maximum collector-emitter voltage of 60V. It is RoHS compliant and has a pin designated as the emitter, one as the base, and one as the collector, allowing for efficient transfer of currents. Additionally, due to its surface-mount design, its low height and large power capacity make it suitable for use in power-constrained applications such as mobile devices.
