FAQ: Does MLCC Capacitance Change with Voltage?
When an engineer designs a circuit, he or she needs to ensure that each component will "do what it says on the box." In multi-layer ceramic capacitor (MLCC) design, one area that often concerns …
How to choose capacitor voltage rating for ESD protection?
That internal resistance (and the ESD capacitor in question) form a low-pass RC network that significantly limits the build-up of voltage across that ESD capacitor. In the picture below, the 150 pF capacitor is charged up to (say) 8 kV.
8.2: Capacitors and Capacitance
How much charge is stored in this capacitor if a voltage of (3.00 times 10^3 V) is applied to it? Strategy Finding the capacitance (C) is a straightforward application of Equation ref{eq2}. Once we find (C), we …
Capacitor Basic Calculations
Capacitors are used in many circuits for different purposes, so we''re going to learn some basic capacitor calculations for DC circuits. In the paragraph: "If we needed to store a charge of say 0.0002 coulombs then we just divide this by the voltage, in this case 12V to see we need 0.0024 Farads or 2,400uF microfarads."

If a capacitor has a low voltage rating, why isn''t it damaged by low current, high voltage …
Capacitors usually have a voltage rating marked on them. From what I gather, it''s the maximum voltage it can withstand without being damaged. Let''s assume you have a 35V capacitor and you rub your feet on the carpet to …
8.2: Capacitance and Capacitors
If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …
Capacitor voltage ratings: how much higher can I go?
I''m recapping a couple amps and CD players so I need to order a lot of capacitors. One thing I''m not sure about is the voltage ratings though. I searched previous threads and I now I can go higher, but how much higher is okay? For example, I need 47uf caps of 6.3V, 10V, 16V, 25V, 35V and 50V. To...
