What’s the meaning of “CR” marked on the PCB?

C for capacitance. R for resistance. CR for capacitive reactance circuit.

Alternating current can pass through the capacitor. When the capacitor is connected to the AC circuit, the charge on the capacitor plate has a hindering effect on the directional moving charge, which is called the capacitive reactance.
