WebBJT Internal Capacitances There are very small capacitances in a BJT between the collector and the base, and the base and the emitter. Since the capacitor values are very small, their impedance at low and moderate frequencies is large. I.E.: 1 is large if C 1 C Z jC ω ω = In other words, at low and moderate frequencies, these capacitor impedances
