Quality Factor of Capacitor: The quality factor of a capacitor is the ratio of its reactance to its series resistance, given by Q = 1 / (ωRC). Lossy Capacitor: A lossy capacitor can be modeled with a capacitance and high parallel resistance, influencing its efficiency. Every inductor has a small resistance along with its inductance.
getcalc.com's Quality (Q) Factor Calculator is an online electrical engineering tool to calculate the quality or efficiency of capacitor. Quality Factor often called as Q factor is a dimensionless quantity to measure the quality of capacitor. It's a ratio between capacitor's reactance (X c) and equal series resistance (ESR).
The standard frequency used in Q factor measurements is 1MHz. However, since the Q factor varies greatly with frequency, the Q factor given at 1MHz is not a good approximation of the Q factor at, for example, 2GHz. Some datasheets will give Q factor values at higher frequencies if the capacitor was intended for use at high frequencies.
Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance. Capacitive reactance is calculated using: Where Q factor or Quality factor is the efficiency of the capacitor in terms of energy losses & it is given by: QF = XC/ESR Where
You don't check. To choose the capacitor, you go to the manufacturer data sheets of the capacitors, which will have the specifications you need to help you choose. You buy from a reputable distributor, and specify the capacitor you want. That way, counterfeits and substitutions are less likely.
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 of the capacitor, as as well as the materials used.
