Anyone know how to tell the values of these tropical fish caps? Been searching the net for ages and i'm getting nowhere!

Even the Ebay page google keeps throwing up wont tell me!!!!!! lol!

Read on one forum that the resistor codes are the same!!!! Well i know for a fact one of these caps is 1uf and nothing there matches!

Please help, i really want to try these.

Lol! going to have to go to 'how to search the internet' school!  ;)

Cheers mate.

PM me I have a site that does tropical fish capacitors sales. I 'll send you a color code chart/data sheet from Philips who made them.

lol.... add "how to search this forum" to that, and you'll be all set!

No problem at all really.

I have decided to put the full four page data sheets and colorcode charts up on my website. The link will be posted here once they are up. Thank you, Terence

Here are some data sheets and color code charts as given to me by Philips. These are pdf. Converting sizes may have made them a bit out of focus so you may have to zoom to see them better.

Cheers Terence,

Thats better than anything i've ever found!  ;D

You're welcome. Remember the multiplier. You will be getting a high number as the values are in picofarads. One nanofarad is a thousand times greater than one picofarad. One microfarad a million times- so for nanofarads move the decimal three places to the left. For microfarads move the decimal six places to the left. :icon_smile:

i would just meter them.  their value can fluctuate quite a bit.

I appreciate that and have similar feelings towards part fluctuation, over time. But amazingly, I 've had only a handful that have tested outside of the designated parameters, out of thousands I've tested, save of course the small percentage, of obviously bad ones, which I immediately discard. These capacitors, have really kept their capacitance values, as well as any capacitor, I have dealt with. Additionally, I have had extensive experience, with as many of these capacitors, as anyone(truth not bragging) Unfortunately after forty years or more, these capacitors can change dramatically at any time, which make them, a pretty bad risk, in the long run, for consumers considering their addition, to their collection of parts. What is discussed less often, is how humidity can seep through these polydipped capacitors, which can easily, degenerate the parts. Although the capacitance values appear within an acceptable range, that part can still increase in noise and degeneration, over time, which can affect inductance, df and eventually, the capacitance itself. PLEASE CAPACITOR MANUFACTURERS: COULD YOU TEST AND FIND OUT IF ANYTHING SPECIAL, IS FOUND WITHIN THE GOOD ONES OF THIS VARIETY? IF IT HAPPENS, THERE IS YOUR IMPETUS, TO PUT THOSE POSITIVE ANOMOLIES, IN A MODERN, PLASTIC INCASED, MPF CAPACITOR, OF CURRENT PRODUCTION. If theres nothing special discovered, in a major laboratory study, the public will accept the findings and put this legend of "mojo" to bed for good. I promise!
