\nI\u2019ve found that a problem with using electrolytic capacitors to filter \nout the RF noise is their internal ESR, effective series resistance. \nThey don\u2019t filter out the RFI as good as they should. I found that \nMLCCs do a better job, if I used some multi microfarad MLCCs. I got \nsome \u2018106\u2019 or 10 uF, 10V MLCCs which have a very low ESR. They\u2019re better\n than \u2018lytics. You can also use tantalums, but they\u2019re somewhat more \nexpensive. Also some RF chokes that are high current and low \nresistance.<\/p>\n","protected":false},"excerpt":{"rendered":"
