  • Publication number: 20140285949
    Abstract: A hard start capacitor replacement unit has a plurality of capacitors in a container sized to fit in existing hard start capacitor space. The capacitors are 4 metallized film capacitors wound in a single cylindrical capacitive element. The container has a common terminal and capacitors value terminals for the plurality of capacitors, which may be connected singly or in combination to provide a selected capacitance. An electronic or other relay connects the selected capacitance in parallel with a motor run capacitor. The hard start capacitor replacement unit is thereby adapted to replace a wide variety of hard start capacitors.

  • Patent number: 8830655
    Abstract: A capacitor (20A-E) formed as a roll of inner and outer electrode strips (21, 23) alternating with inner and outer dielectric strips (22, 24). Each of the dielectric strips (22, 24) is shorter than an inwardly adjacent one of the electrode strips (21, 23) at a radially outer end thereof (21 E, 23E). This exposes the radially outer end of each electrode strip on respectively different portions of an outer side surface (26, 28) of the capacitor. The exposed ends of the electrode strips may be arranged on opposite sides of the capacitor, such that stacking the capacitors interconnects them either in parallel, in series, or in combinations thereof in different embodiments.

  • Patent number: 8693162
    Abstract: A multi-layered capacitor includes three or more capacitor layers. A first layer includes a first DC-biased, tunable capacitor. A second layer, acoustically coupled to the first layer, includes a second DC-biased, tunable capacitor. A third layer, acoustically coupled to the second layer, includes a third DC-biased, tunable capacitor. Each dielectric of the first, second, and third capacitors has a resonance of about the same frequency, within 5%, and inner electrodes of the first, second, and third capacitors have a resonance of about the same frequency, within 5%. The resonance of each layer is a function of at least thickness, density, and material. The first, second, and third layers are biased to generate destructive acoustic interference, and the multi-layer capacitor is operable at frequencies greater than 0.1 GHz.

  • Patent number: 8649156
    Abstract: In a capacitor body of a multilayer capacitor, one second capacitor portion is sandwiched between two first capacitor portions. An ESR is controlled by setting a width of lead portions of third and fourth internal electrodes disposed in the second capacitor portion to be less than that of lead portions of first and second internal electrodes disposed in the first capacitor portions and by changing ratios between the first and second capacitor portions in the width of the lead portions and in the number of stacked internal electrodes. In the first capacitor portions, current paths from the internal electrodes to an external terminal electrode are widely distributed so that the first capacitor portions have a relatively low ESL, and accordingly, the ESL of the entire multilayer capacitor is reduced.
