A monolithic multiple ceramic capacitor is made by interspersing layers of green tape containing ceramic powder in a binder with printed layers of electrical conductors, then compressing the layers and heating them to sinter the ceramic powder. Edge connections link the conducting layers in predetermined patterns to provide external connections to the capacitors. Use of parasitic or stray capacitance between pairs of external terminals provides additional useful values of capacitance. Unwanted stray capacitance between adjacent terminals is reduced by making slots by saw cuts or the like in either the green tape or the sintered material. Unwanted stray capacitance between elements inside the capacitor is reduced by ground planes between layers of capacitors and by layers of ceramic materials having relatively low dielectric constants to separate layers of capacitors, to form exterior layers of insulating material, or both.
