Capacitor Value Calculator (and Code Calculator)
Let''s break that 3 digit code! The first two digits are the capacitance value in pF and the third digit is simply a multiplier. This is where you need a good memory, or the calculator! The multiplier is always a number between zero and six. If …
capacitor
The word "capacitance" means the ratio between the charge and the voltage. If we have two capacitors, and both of them have a charge of $1 mathrm{mu C}$, but one of them has a voltage of $10 mathrm{V}$ and the other one has a voltage of $1 mathrm{V}$, then the first one is defined as having a capacitance of $0.1 …
