ABSTRACT OF THE DISCLOSURE: A trimmer capacitor having coarse and fine adjust- ments. The trimmer is made up of a common stator element and two rotor elements cooperating with respective trimmer adjustment ele- ments to vary the capacitance of each individual capacitor compo- sed of each one of said rotor elements and said common electrode. For large overall capacitances, one rotor element has a large capacitance, for coarse adjustment, whereas the other rotor element is of small capacitance for fine adjustment, the two rotor elements being connected in parallel with the common stator ele- ment. And for small overall capacitances, one rotor element has a small capacitance for coarse adjustment whereas the other rotor element is of large capacitance, for fine adjustment, the two rotor elements being connected in series with the common stator element.
