element14 has been talking about polymer capacitors a lot in the last few months. Before we talk too much, we thought we would give Community members a chance to show their stuff. We wrote a 25-question quiz on polymer capacitors for you to take. Have fun!

After you have answered all the questions, click "Submit Answers." Once you have scored a 100%, leave a comment on this page, and give the page a rating and you will earn a Polymer Capacitor badge. If you don't get a perfect score, that's fine. You will be given a link to the sources used to write the quiz. You can take it as many times as you want.

This quiz is interesting to known more details about the capacitor types and their usage in circuit. Would like to participate in more similar quiz. Thanks for the organizers.

Seeing this immediately reminded me of the Oscilloscope probe shock video by EEVblog.

I'd definitely think about this in the future for sensors on machinery. (Though to be fair the only problem I've had so far is Large SMT electrolytic's falling off if not glued. we changed to through hole on future builds.)

Hi Rusgray
As far as I know, the distortion performance refers to temperature stability and physical effect which could be found in the whitepaper below:

Hi James,

I don't expect them to be much different to alu electrolytic, otherwise firms would have leapt at the chance to charge plastic film prices.
I'm still curious to do the test to see if it is measurable this way. I was thinking about how to go about it, and it's applicability for reuse too, because the same procedure could be used to test audio amps too.

Anyway, I'm just throwing the idea out there.. to see if is interesting or not. I've plenty to work on, so won't pursue this unless there's a real need.

but I don't know how it compares to electrolytic

Keep in mind that what the industry calls "polymer capacitors" are still electrolytic capacitors made with aluminum (or tantalum). The polymer is part of the cathode, not the dielectric. Distortion isn't going to be much different from Al or Ta.

(It would have been better to call them "polymer electrolytic" to avoid confusing them with plastic film, but no one has done a great job of using the proper name.)
