MultiCapTM - Metalized Polypropylene Multiple-Section Capacitor

The PPMFX series of the MultiCapTM reduces typical capacitor loss factors with a patented design that winds capacitors coaxially one upon the other, into a single, self-bypassed unit. Since each section is parallel, the inductance of the overall capacitor is reduced by the number of sections used - typically 10. Inductance characteristics never exceed those of a piece of lead wire the same length as the capacitor's body; measured ESR values are 5 to 10 times lower than conventional designs (see Figure 1). The PPMFX MultiCapTM is recommended for lower current applications. With its overall reduction of parasitics, this series is ideal for use wherever low ESR, low DF, high resonant frequency, high performance, and small size are important, and wherever metalized capacitors are in use.
