Lowest hfe 2n

Web10 nov. 2012 · hfe is niet de dc versterking, maar de kleinsignaalversterking. De hfe curve is meestal bij kleine stromen vrij lineair, om bij grotere stromen af te buigen. Vandaar dat men hfe als richtwaarde opgeeft bij een redelijk kleine collectorstroom. Hfe is ook niet koudweg Ic/Ib, wat slechts een punt op de curve betekent.

Thus, a low current at the base terminal can be used to drive a high current between two other terminals. 2N2222 is used for switching applications or low power amplifying. It can also be used for pulse width modulation as its response time is fast. hunk\u0027s t9
