![]() ![]() since it adds to the coil or capacitor resis. Visit the capacitor section at to find the capacitor you need and find the information on the datasheets provided. Eq 1 where XS and RS are the series reactance and loss resistance, and RP and XP are the. This would mean a change in the material, leading to higher costs but will produce better results. Clean solder joints will also help with the resistance. Some things you can do to reduce this resistance is increased quality of the pads and conductors. To minimize the dissipation factor in your circuit you may need to choose a capacitor with a higher Q factor and reduce the resistance in the circuit. Q factor can be found with capacitor reactance divided by ESR or Q = Xc/ESR. ![]() Generally, when designing a simple passive RLC filter, the steep. Depending on the arrangement of series or parallel impedance ratios, it may be a bandpass or bandstop filter, or even HPF or LPF with peaking caused by Q>1. The Q factor is the mathematical reciprocal of the dissipation factor as DF decreases QF increases. With a series or parallel LC filter, the shape is also defined by Qfo/f for the resonant f fo and -3dB bandwidth f. The equation for the dissipation factor is the series resistance divided by the capacitive reactance or shown as DF = Rs/Xc.Īnother term that you may see more is the Q factor or quality factor. This temperature increase can be maintained with add on components such as fans and heat sinks but will add weight and cost. Externally, the leads, pads, and solder all lead to an increase in resistance.Ī high dissipation factor may lead to diminished life of the capacitor and cause deterioration of electrical properties of other components affected by the temperature increase. This power is either absorbed by the dielectric material or internal/external resistance. ![]() The dissipation factor of a capacitor is the power loss when AC is applied through the capacitor. ![]()
