I see diiferent values being used on phantom blocking caps. Looking at the INA217 datasheet the blocking caps are shown as 47uf electros. But when I built the SSL9K, it used 2.2uf caps as phantom blockers. I have some 2.2ufs left over from that project and wanted to know if I could use them for blocking caps in the 217 circuit. What I am really asking is how important is the value of the phantom blocking caps?
