2. 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…
