Capacitor series codes

[James B]

Hi

I'm currently fixing a car alarm for my Saab which has suffered a common fault with capacitor failure. I'm trying to find equivalent capacitors online (Maplin don't have the ones I need). I have the values (farad and DC voltage values for electrolytic aluminium caps), however there is also a 'series' number (FA) written on the side of the capacitors in the alarm module. The equivalent ones I have found online have series (FM) written on them. I've researched this but can't find much and not sure if these are compatible or what the code actually means? Would really appreciate any advice!

Thanks

Hi James
What value and voltage rating are the caps.

Hi

They are:

10v 220uf
16v 10uf
25v 330uf

The FM series are not recommended for automotive use. The FA series looks like it's discontinued also, but you might be able to match another capacitor. http://industrial.panasonic.com/lecs/www-data/pdf/ABA0000/ABA0000CE72.pdf
Let me see if I can find something.

Thanks for your help. I had no idea there would be a difference! I found this doc useful:

Its seems FK, FT and FP might be best?
