on start capacitors 10% variation won''t be a problem. But on RUN capacitors the mfd should not vary (can go up on voltage but mfd should be same) Get Copeland''s electrical handbook and learn how to combine Capacitors in parralel and series so you can always provide proper mfd:
A couple reasons come to mind. Lower ESR. The effective ESR of the capacitors follows the parallel resistor rule. For example, if one capacitor''s ESR is 1 Ohm, putting ten in parallel makes the effective ESR of the capacitor bank ten times smaller.
A parallel plate capacitor with a dielectric between its plates has a capacitance given by (C=kappa varepsilon _{0} dfrac{A}{d},) where (kappa) is the dielectric constant of the material. The maximum electric field strength above which an insulating material begins to break down and conduct is called dielectric strength.
The voltage and MFD range of the run capacitor should be as close to factory spec as you can find. Typical capacitor tolerance is +/ 6% of the factory spec. Now review the mfd specifications. The mfg of the capacitor should be close to the original - it is ok if it is off just a bit, say 5%. What happens if we install a mis-matched capacitor:

It seems all those capacitors are on 5v, look what it says on them, if it says 6.3v or 10v, then 100 percent they''re filtering 5v. Having so many go bad can be a sign that the power supply has started to fail and outputs a bad quality 5v voltage - could still be within reasonable values if you check with multimeter but during use and higher load the …

Now if you replace that electrolytic with a different type of capacitor, say a film type for example, the tolerances are much tighter so you …
What is the effective capacitance of two ( 2, text{nF} ) capacitors in parallel? The effective capacitance is given by [ 2, text{nF} +2, text{nF} = 4, text{nF}.
If value is not within ±10 percent value stated on capacitor, it should be replaced. If capacitor is not open or shorted, the capacitance value is calculated by measuring voltage across capacitor and current it draws. Use following formula to calculate capacitance: Capacitance (mfd)= (2650 X amps)/volts 3. Remove any capacitor that …
If these two components are still struggling to start, they may have been permanently damaged from the failing capacitor that was just replaced. You should see a marked difference. Everything should now be working properly, and your room should begin to cool down. Get the Repair Parts You Need. Capacitors; A/C Capacitor …
If a circuit contains a combination of capacitors in series and parallel, identify series and parallel parts, compute their capacitances, and then find the total.

When a voltage (V) is applied to the capacitor, it stores a charge (Q), as shown. ... Common capacitors are often made of two small pieces of metal foil separated by two small pieces ...
The capacitors combine in parallel, so 10 + 220 equals 230 microfarads. We can keep adding more such as a 100 microfarad capacitor. And the total is just the sum of all of the capacitors.
Capacitor technology since the late 80''s is such that you shouldn''t have to worry about them failing in even 15-20 years. Realistically, probably more than double that these days (30-40 years).
The other things you need to pay attention to are the voltage (370 or 440) and tolerance (+/- %) ratings on each of the capacitors. 1. The replacement capacitor''s voltage (370 or 440V) rating should be the same or higher than the original one 2. The replacement capacitor''s tolerance (+/- %) rating should be equal to or lower than the ...
The capacitor leaks oil. This doesn''t always happen, but bad capacitors frequently have oil leaking out of them. A leaky capacitor = a capacitor that''s past its prime. And there you go! That''s how you know you need a new AC capacitor. Sometimes, an old, rusty-looking capacitor will still read at the appropriate level of microfarads.
