What is this capacitor?
« on: April 28, 2015, 08:47:28 am »
Well I have been exploring the CD4001, 4013, 4016, etc... IC's and I have been finding a number of circuits that require a 10n or 100n non polorized capacitors and wondering what are they, the Google searches I have done, all came up empty.

I tried building a few already, only to have them fail.

Here is a link to one project: http://startingelectronics.org/beginners/start-electronics-now/tut17-electronic-dice/

I'm just planning on doing an order on eBay next chance I get.

Well a 10n or 100n non-polarized capacitor could be made by a wide variety of different technologies. In practice for general purpose stuff it will most likely be a (multi-layer) ceramic capacitor. Plastic capacitor (polypropylene etc.) used to be common previously but nowadays are used in more special applications (where for example the microphonic properties of ceramic capacitors could be a problem).

The non-polarized capacitors, I have or I have looked up all have two letters, not just one. Is the site I am looking at not adding the 'f', as PA0PBZ is pointing out, it is just a 100nf (103) capacitor?

If you are asking if the "n" refers to the capacitance which is measured in farads, then yes. A 10n cap means a 10nF (nano farad) cap...
Just like the resistors, a 2k2 resistors means a resistor with a resistance of 2200 Ohms.

The pictured cap is 10nF (10 x 103 =10.000pF), not 100nF which would be 104.
Without a letter the capacity is almost always shown in pF.
