Hi All
 I need help to understand calculating the equivalent ESR of capacitors in
parallel. For example if we have tant capacitor with 65mOhm ESR and a
ceramic cap with 10mOhm ESR, whether the equivalent ESR is simply the
parallel of these two ESRs? If it is so simple then we can always keep one
ceramic and tantalums in parallel to achieve low ESR as ceramic always will
have low ESR?


Thank you,
Sree
