WebbSome capacitors are defined by a three number code followed by a letter. This letter represents the tolerance of the capacitor, meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor. The tolerances are indicated as follows. Read B as 0.10 percent. Read C as 0.25 percent. Read D as 0.5 ... WebbIn any HVAC unit, the capacitor must match the motor. The voltage can go higher if necessary but never lower, while the MFD (uf) should always be the same. In the picture, this is a Dual Run Capacitor and reads 55+5 MFD (uf) 440 VAC. The larger number 55 MFD is for the compressor, while the lower number 5 MFD (uf) is for the fan motor. simpleaffy安装包
