  • Patent number: 5973907
    Abstract: Multielement capacitors have at least one metal capacitor and at least one ceramic capacitor with common terminals in a common case. The preferred metal capacitance elements have an effective series capacitance of at least 1 microfarad at frequencies of up to 100 kHz. The individual metallic capacitance elements exhibit an ESR of less than 100 milliohms at 100 kHz and a dissipation factor (DF) of less than about 6% at 120 Hz. The ceramic capacitance elements useful in the invention have an equivalent series capacitance of at least about 0.1 microfarads at frequencies of up to about 100 MHz. The individual ceramic capacitance elements have an ESR of less than 20 milliohms at 1 MHz and a dissipation factor of less than 10% at 1 kHz.
