2018-11-16 Low ESR MLCCs

I’ve found that a problem with using electrolytic capacitors to filter out the RF noise is their internal ESR, effective series resistance. They don’t filter out the RFI as good as they should. I found that MLCCs do a better job, if I used some multi microfarad MLCCs. I got some ‘106’ or 10 uF, 10V MLCCs which have a very low ESR. They’re better than ‘lytics. You can also use tantalums, but they’re somewhat more expensive. Also some RF chokes that are high current and low resistance.
