Hi Neil. At at least for TTL, 0.2 uF is probably OK. Don’t want it much larger than that because you are counting on a kind of noise RC filter arrangement. In the past I used to get my 0.1’s from Jameco. But these days they supply them on a reel type tape. It’s a real pain to cut them out, separate the leads each time etc. I like the Mouser blue colored caps (MFG Part No:FK28X7R1H104K). I get them in lots of 500. The nice thing is they are all separate and the leads are correctly spaced for our boards. John From: n8vem...@googlegroups.com [mailto:n8vem...@googlegroups.com] On Behalf Of nbreeden I'm curious as to others opinions about decoupling caps. These are typically 0.1uF disc caps which is what is specified for all of the various boards in the N8VEM family. In a grab bag I recently bought I found a large number of 0.01uF and 0.2uF disk caps (over 1000 of each). What are your thoughts on using these? -Neil -- |
