    I’ve put off ordering from digikey because they seem to have so few different uf sizes in the range we typically use. Am I missing something?

    At the link below…..I see a 0.22uf and a 0.15uf. Nothing in between. Am I missing something?

    Some of the Mercury mags call for 0.18uf…..

    No. you’re not missing anything, that’s what Vishay has to offer in this series of caps. A .22 uF cap would be the logical choice for your Merc mag. Another option might be an Orange Drop cap but they are large and hard to fit. They are more suited for motors from the 20’s – 40’s which had lots of room under the flywheel.

    Here’s something I saved from the old blue boards explaining the P/N’s and applications of the MKP1839 caps. Thanks again Jeff!

    I guess that’s not going to happen. Wordfence won’t let me attach the file. I’ll try it again later doing it another way.
