What does the F on a capacitor mean?
farad
The farad (symbolized F) is the standard unit of capacitance in the International System of Units (SI). Reduced to base SI units, one farad is the equivalent of one second to the fourth power ampere squared per kilogram per meter squared (s4 · A2 · kg-1 · m-2).
What capacitor do I need for my amp?
The rule of thumb is to put in 1 Farad of capacitance for each watt of power. Many see benefits with 2 or 3 Farads per 1,000 watt RMS, and there is no electronic penalty for using larger value caps. The bigger the cap, the quicker it gets ready for the next hit.
What are 100uF capacitors used for?
All three of the 100uF capacitors appear to be used for decoupling. C4 is placed right next to the input of the voltage regulator. Its purpose is to reduce the noise on the incoming power line (specifically to overcome any impedance to the current flowing in).
How many microfarads are there in one farad?
1000000 µF

Do I need a capacitor for a 1200 watt amp?
A: The rule of thumb is to put in 1 Farad of capacitance for every 1,000 watts RMS of total system power. But there is no electronic penalty for using larger value caps, and in fact, many see benefits with 2 or 3 Farads per 1,000 watts RMS. The larger the cap, the more charge is available for the amp when it needs it.
