He aha te Q-Factor o tētahi inductor?

Ko te Kounga Whakarite (Q-Factor) o te inductor he ine o te pai o te rokiroki i te pūngao pāni i te tārohia ki te pūngao e ngaro ana i te wā e mahia ana. He mea nui ia i te whakaū i te whakatutuki o te inductor, i roto i ngā hiko RF, ngā paearu hakahaka, ngā lọta, ngā pūhiko, me ngā tono pānga anga.

Ko te inductor tino pai e rokiroki ana i te pūngao me te kore ngaro. I te whakamahinga, e ngaro katoa ana te inductor i ngā hautūtanga, ngā ngaro pokanga pāni, me ngā pānga pāpori e tere huri ana i te wāhanga o ngā pūngao rokiroki ki te wera. Ka āwhina te Q-factor ki te ine i ēnei ngaro.

Me pēhea e whakaritea ai te Q-Factor

Ko te Q-factor e tohu ana hei te ratio o te reactance inductive ki te hautūtanga raupapa whaihua i runga i te auau e tū mai ana.

I reira:

• Q = Kounga Whakarite

• XL = Reactance Inductive

• f = Auau e mahi ana

• L = Inductance

• RESR = Hautūtanga Raupapa Whaihua

E whakaatu ana tēnei tauanga ko te pikinga o te Q-factor e tupu ana i te wā ko te reactance inductive teitei, ā, ka heke ana te ngaro i te wā e nui ana.

X_L=2π(10×10⁶)(10×10^-6)

X_L≈628 Ω

Nā, whakatauhia te Q-factor:

E tohu ana tēnei i tētahi inductor Q-runga e tika ana mō ngā tono RF me ngā paearu hakahaka.
