IMPEDANCE VS FREQUENCY (TYPICAL)
The left-hand portion of the curves represents the
capacitive reactance of two typical values. The
impedance decreases until series resonance is reached.
At this point (the bottom of the V), the only component
of the impedance is the ESR. At higher frequencies (the
inductive portion) the ESR remains relatively low so that
effective filtering is maintained. |

ESR VS FREQUENCY (TYPICAL)
These curves reflect the very low ESR of two typical
values. These ESRs are much lower than Tantalums or
Aluminum electrolytics of the same values. The result
is the ability to provide filtering (low loss) and to handle
high power requirements. |

RIPPLE CURRENT VS FREQUENCY (TYPICAL)
Here are two examples of the ability of Switch-Mode
capacitors to handle high values of ripple current (high
power) at various frequencies. Refer to the “AC Power
Computations” applications note or contact AMC
Applications Engineering for more information. |
