Many good capacitors wil have ESR lower than shown above, that is good. O Values in this table are calculated from publ'shed dissipation factors for Panasonic@ FR-Series capacitors from

The Atlas ESR is an advanced instrument designed specifically for the analysis of capacitor equivalent series resistance (in or out of circuit). In addition it will, where possible, display the capacitance of the device under test. ESR measurement range 0 to 20 (40 for ESR70). ESR resolution as low as 0.01 . Capacitance range 1AF to 22,000AF.

We'll look at an easy way of estimating ESR with test equipment you may already have. To check a capacitor's ESR, here's the basic test circuit: An AC voltage source supplies a voltage V 0 to a voltage divider composed of R 1 and R 2 .

ESR values cover a huge range. A good low voltage capacitor of thousands of µF can have an ESR of much less than 20mΩ (0.02Ω) while a 1µF 400V cap might read over 30Ω and be quite OK. The chart on the front of the meter gives some fairly typical figures for a range of common electrolytic capacitors. I've reprinted a more detailed chart at ...

Questions continually arise concerning the correct definition of the ESR (Equivalent Series Resistance) of a capacitor and, more particularly, the difference between ESR and the actual physical series resistance (which we'll call Ras), the ohmic resistance of …

Low ESR tantalum capacitors can improve circuit power efficiency, reduce heat generation for the circuit, and increase low-term reliability. When choosing a capacitor for any application, there are a few key characteristics that must be understood in order to analyze its suitability for the circuit.

This application note describes how to measure the equivalent series resistance (ESR) of a capacitor using the Bode 100 vector network analyzer in conjunction with the B-WIC Impedance Adapter. The ESR1 of a capacitor strongly influences its characteristic behavior.
