The Methods and Problems of Capacitor ESR Measurement
There are many different types of capacitors with many different parameters; each is suited to a range of applications. As operational frequency requirements increase, electronic systems downsize and power usage becomes more critical, the most important parameters are quality factor (Q) and equivalent series resistance (ESR). …
Q Factor Measurements on L-C Circuits
8 QEX – January/February 2012 capacitor, C, for resonance to maximize the voltage across the resonating capacitor C. The Q is calculated using Equation 2.Voltage Across Source Voltage C Q = [Eq 2] Note that the source voltage is in the millivolt range, since it
Equivalent series resistance
Capacitors and inductors as used in electric circuits are not ideal components with only capacitance or inductance.However, they can be treated, to a very good degree of approximation, as being ideal capacitors and inductors in series with a resistance; this resistance is defined as the equivalent series resistance (ESR).If not otherwise …
Tips and Techniques for Capacitor Testing
For making high resistance measurements on capacitors with high voltage ratings, a 1000V source with built-in current limiting is best. For a given capacitor, a larger applied voltage within the …

What resistance should I expect when testing capacitors?
There are no visible signs of bursting or leaking on any of them so I''ve started measuring the resistance using a multimeter, however I have no idea what I''m actually looking for. Testing a 35V 2200µF capacitor shows a gradually increasing resistance that plateaus at around 730Ω.
Q & ESR Explained
Typical values for a good high frequency capacitor of a given value could run in the order of about 0.05 ohms at 200 MHz, 0.11 ohms at 900 MHz, and 0.14 ohms at 2000 MHz. The quality factor Q, is a dimensionless number that is equal to the capacitor''s reactance divided by the capacitor''s parasitic resistance (ESR).

Understanding ESR and ESL in Capacitors
Measuring ESR in Capacitors. Measuring the ESR of a capacitor is bit tricky because the resistance is not a pure DC resistance. ... The Vs is the sine wave source and R1 is the internal resistance. The capacitor C is the Ideal capacitor whereas the R2 is the Equivalent Series Resistance of the ideal capacitor C. ... high quality …
How to Measure Resistance
However, resistance measurement does not involve measuring the circuit''s resistance value itself. Instead, resistance is calculated by measuring the current and voltage applied to the circuit. When a current is applied to the circuit under measurement, the circuit (resistance) exhibits a voltage (or more precisely, a voltage drop).

In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is defined as the ratio of the initial energy stored in the resonator to the energy lost in one radian of the cycle of oscillation. Q factor is alternatively defined as the ratio of a resonator''s centre frequency to its bandwidth when subject to an oscill…
