Electrolytic Capacitor Tolerances
Secondly, does the consistency of the measured DC capacitance across a number of different capacitors give me any indication of the consistency of actual capacitance values in AC? In other words, is it likely/probable that while all the caps measure the same at DC, that they could deviate significantly from each other at, say, …

RC Charging Circuit Tutorial & RC Time Constant
Notice that the charging curve for a RC charging circuit is exponential and not linear. This means that in reality the capacitor never reaches 100% fully charged. So for all practical purposes, after five time constants (5T) it …
What is the Capacitor Symbol on a Multimeter
Capacitor damage: If the capacitor is damaged or aged, it may not work properly, resulting in a multimeter that cannot measure an accurate capacitance value. Reverse connection of polar capacitors by mistake: For polar capacitors (such as electrolytic capacitors), the connection of positive and negative electrodes is very …
measurement
Short answer: No. A capacitance measurement will only give you part of the picture. You also need to measure the ESR, especially for electrolytic capacitors. …
Q factor | Fundamentals | Capacitor Guide
Good high-Q capacitors can have a Q factor value of over 10,000 at 1MHz and over 1,000 at 100MHz, while standard capacitors can have a Q factor as low as 50 at 1kHz. The difference between a high-Q capacitor and a standard capacitor is in the actual design
