Re: 8656B & Surge Suppressor


 

I like Kemet caps also, but there are lots of good brands. In general, anything you buy from Amazon, ebay and the like is often fake, rejected parts or bad. I stick to real distributors, Mouser, Digikey, Newark, Arrow, etc.

I use to do searches. They will show what the various prices are and who has stock. All the distributors now will sell small quantities online. For very small quantities, I find Digikey's shipping to be cheaper.

There have been multiple discussions here about the "best" caps to use. It depends on the specific application. All the distributors have online sites that allow you to put in specs. capacitance, voltage rating, temp, size, tolerance, etc, and narrow down to what you need. I generally do that. Sometimes the "right" part just falls out of the search.

I use Surgex surge protectors, which are expensive but not MOV based. K9YC's site has lots of explanation as to why MOV based surge protectors have issues. I found them on eBay for a good price.
