Early metallized film capacitors were identified by CJ, and similar non metallized film paper capacitors were identified by CZ. Now, due to advanced production technology, organic film is easy to use, metal evaporation coating process is simple, and the frequency characteristics are better than pape

Metallized film capacitors emit the sound of Zizz when they pass alternating current. One of the reasons is that the self-healing sound that is specific to the membrane capacitance is not going to be very loud, and it's going to fade over time, and if you disappear, you have to pay attention to the
