    Replacing RIFA X/Y MP capacitors with ceramic

    This is because I thought the leakage current would not easily increase with ceramic capacitors. Due to the high temperature and humidity in Japan, film capacitors are not an eternal component.

    Replacing RIFA X/Y MP capacitors with ceramic

    Since the modern hardware may use ceramic safety capacitor and may not use film capacitors, I think ceramic mods are possible on the Mac as well. There is no 0.1uF in the DE2 SA lineup. Also, ceramic capacitors tend to change their capacitance when AC voltage is applied. I think this requires...

    Replacing RIFA X/Y MP capacitors with ceramic

    I'm not talking about replacing non-X1/Y2 capacitors. I'm considering switching to Murata DE2 SA. DE2 SA is the X1/Y2 certified safety ceramic capacitor! However, the capacitance of DE2 SA seems to be significantly different from that of MP/film capacitors.

    Replacing RIFA X/Y MP capacitors with ceramic

    I know it is possible to purchase new MP capacitors, but since security capacitors are not filters, there is no electrical meaning to inheriting the material. Besides the high dielectric absorption of metallized paper, I don't think it can withstand surge voltages when degraded.

    Replacing RIFA X/Y MP capacitors with ceramic

    I'm going to remove the RIFA X/Y capacitor from my friend's Mac Plus, but like the Murata DE2, today's X/Y capacitor has become an immortal material through the transition from metallized paper to film. So I'd like to purchase ceramic X/Y capacitors or utilize capacitors scavenged from wasted...
