In the context of electrical engineering, the filter factor of a reactor refers to a measure that indicates how close a reactor is to being a pure inductor or capacitor. It helps in determining the quality factor (Q-factor) of the reactor, which describes its resonant behavior. A higher filter factor means that the reactor behaves more like an inductor, while a lower filter factor means it behaves more like a capacitor.
