Low ESR Capacitors
What is ESR?
ESR is an abbreviation for Equivalent Series
Resistance, the characteristic representing the
sum of resistive (ohmic) losses within a
capacitor.
While ESR is undesirable, all capacitors exhibit it
to some degree. Capacitor manufacturers look to
ways to reduce the ESR of the capacitor…
