How to Read Capacitor Values? (Electrolytic, Ceramic, SMD)

For that, we need to calculate the capacitance value similar to the SMD tantalum capacitor. Tolerance. Film capacitors are the most precise capacitors in terms of their capacitance value, which means they have a very less tolerance value (Range – 0.1% to 5%) as compared to other types of capacitors.

How do you calculate the profit of a film? : r/boxoffice

You can then fit a model to the data, and make an interpolation to figure out what (gross/budget) a profit/loss ratio of 1 corresponds to. In my basic-bitch plot from 2 years ago, it''s roughly 3x. So the conclusion from babies first box office data analysis is that a film needs to gross 3x its production budget in order to be profitable.

Calculating ESR of a capacitor

$begingroup$ @Jess for non-polarized ceramic (e.g. X7R, NP0, etc) capacitors, ESR-vs-frequency and Z-vs-frequency graphs are usually given in the datasheets. When it comes to electrolytic capacitors, you may not calculate the ESR but measure it instead. As the frequency increases, the Z of the capacitor increases as the effect of L (a.k.a. ESL) …

Calculating ESL of a Capacitor – C3STREAM Land Designs

Impedance of Various 100μF Capacitors : The figure tells us that the impedance of a capacitor will decrease monotonically as frequency is increased. In actual practice, the ESR causes the impedance plot to flatten out. As we continue up in frequency, the impedance will start to rise due to the ESL of the capacitor.
