# Apple IIe RIFA Capacitors 2022-05-30 There are two #RIFA #capacitors in the Apple II power supply unit, a.k.a. #PSU, that are prone to blowing out and a fuse that may or may not need to be replaced. After watching so many restoration videos, I came to the conclusion that replacing these capacitors should be the first repair done if you intend to embark on a restoration journey. You'll find below the specifications and a video from *lmull3* explaining how to do it. ### Specifications * 0.1uF 100nF 275 Vac CLASS X2 CAPACITOR * 0.47uF 470nF 275 Vac CLASS X2 CAPACITOR * GLASS FUSE F2A 250V ![[vladcampos.com/_photos/2022-05-30-apple-iie-rifa-capacitors.jpg]]  <button>[[vladcampos.com/Static/Builds/Apple IIe/The Apple IIe Project|The Apple IIe Project]]</button> ![[vladcampos.com/Timeline/Blog/Posts]]
