The fan is not a precision electronic appliance, as long as the voltage and capacity of the two capacitors are the same, they can be replaced and used with each other. The cost of CBB capacitor is lower, and the electrical performance can be replaced under the condition of meeting the actual DC voltage resistance. CBB capacitor plays a starting role in the circuit of the fan.
Using a slightly larger capacity than the original capacitance will not affect the normal operation of the fan
As long as the capacity and pressure are satisfied, it is OK. Many fan capacitors are originally CBB capacitors.
