Can anyone refresh my memory on the rules regarding the use of two polorized capacitors for use when you do not have the right value (1000Uf, 300 V)?
You will need 2, 2000uF electrolytic capacitors rated at least at 150V each. The rule is double the required capacitance, divide voltage by half. Since you will be wiring them in series, each capacitor will see 1/2 the applied voltage. But because you are in series, capacitance will be divided by half, thats why you have to double it. + – + – – + – + —](—*—)[—- or —)[—*—](— 2000uF 2000uF 2000uF 2000uF 150Vmin 150Vmin 150Vmin 150Vmin Note: Make sure your capacitors are the same capacitance. If you use caps that are from 2 different manufactures or the capacitance are quite different, the voltages will note divide equally on each cap, possibly exceeding the 1/2 rule for voltage. If that happens, you will learn a lesson the hard way, like I did, and have the capacitors heat-up, bulge and explode! CAUTION from another tech: There is only one way to connect 2 polarized capacitors in series. The (-) of one cap must be connected to the (+) of the other cap to maintain proper p
