I'm looking at two capacitors and trying to decide which would be the
better of the two for filtering digital noise in a circuit. My
knowledge level falls short in interpreting the stat sheets. Maybe
someone here is versed in the nomenclature & can help me understand.
Both caps are 100uf/16V
ESR 100kHz to 300kHz (m) (max.)
Cap A - 32
Cap B - 10
Allowable ripple current (mArms):
Cap A - 2890
Cap B - 4500
Tangent of loss angle (max.):
Cap A - 0.07
Cap B - 0.10
Leakage current (A) (max.)
Cap A - 160
Cap B - 500
I know lower ESR is better which A has, but Cap B allows a greater
ripple and leakage current which seems to me to allow less filtering.
I am thinking A is a more effective filter for digital noise But I am
guessing. If someone understands what's what here, I'd appreciate
knowing.
Thanks much,
Gary
