Cofiring
Hello editors,

I have a comprehension: the link for 'cofiring' is supposed to be this one: https://en.wikipedia.org/wiki/Co-fired_ceramic

if I'm right - it would be wonderful if one of you will change what necessary. Thank you, Itay Benjamin Sendler.

Coding
In my limited knowledge, i beleive that ceramic disc capacitors are coded with a 3 digit code, i think it would be useful if somebody more well informaed than myself could add information about these codes - eg how to understand them and relate them to microfarads etc. Maybe include a link to a site with a table of values?

--sandeep, RF-Engineer 11:11, 8 February 2007 (UTC) A Ceramic capacitor consists of a wafer of ceramic material between two silver plates. Leads are connected to the plates & the entire assembly is encased in a protective plastic shield. This type is called a ceramic capacitor or because of its most comman shape a ceramic disc. Some ceramic capacitors however are enclosed in rectangular cases. There is no electrical differences & often the rectangular units are called ceramic discs anyway.
 * That's actually more useful than the article its self. How about adding this to the article? 75.100.155.122 06:50, 19 July 2007 (UTC)

HF use of Ceramic
I think the statements about the satisfactory use of ceramic caps in Very High Frequency is incorrect. I believe that at very high frequency - such as radio frequency - ceramic caps are not ideal. Maybe there should be a distinction - that at frequencies up to 100KHz, ceramic is OK - above that - ceramics are not ideal.

Modern ceramic capacitors have excellent high frequency performance, with ESLs in the tens of picohenry range. Please be sure that you use recent information, as the rate of improvement is rapid in this field. — Preceding unsigned comment added by 129.55.200.20 (talk) 13:06, 18 August 2011 (UTC)

not clay-coloured ceramic caps
we are very familiar with the darker-orange clay disc capacitors. i have found some grey-greenish types in a monitor - are these any different? there is no additional codes on them.Charlieb000 (talk) 22:48, 5 March 2012 (UTC)

Merge EIA Class 1 / Class 2 articles
The caption of the articles EIA Class 1 dielectric and EIA Class 2 dielectric are misdirecting, the classes of ceramic capacitors are standardized after EIA and IEC. The content of both articles are complete available in the article Ceramic capacitor within the paragraph Ceramic capacitor and include EIA and IEC coding.

I propose to delete the articles EIA Class 1 dielectric and EIA Class 2 dielectric because the content is already within the excisting article ceramic capacitor and make a redirect from EIA Class 1 dielectric and EIA Class 2 dielectric to ceramic capacitor each.--Elcap (talk) 07:36, 1 May 2013 (UTC)
 * Waiting now 4 days none has indicated, that he don’t agree. So I have deleted the text to EIA Class 2 dielectric and EIA Class 1 dielectric and made a REDIRECT to Ceramic capacitor. --Elcap (talk) 07:50, 4 May 2013 (UTC)

Barrier layer types are "starting to compete" with electrolytics? Or are they obsolete?
Which one is it? This part of the article lacks unity.216.31.219.19 (talk) 21:53, 18 June 2013 (UTC)
 * IEC class 3 ceramic capacitors are obsolete. But I have to say "almost obsolete" because some manufactures describe their material not clear enough, mixing class 2 and class 3 and IEC and EIA specs. --Elcap (talk) 09:42, 19 June 2013 (UTC)

False information
The article implies strongly that MLCC means surface mount, but it only is a type of internal construction. I have a box full of leaded (meaning they have through-hole wires, not a surface mount chip) MLCCs. I don't have a cite, and I don't want to post original research, but people using through-hole construction have just as much access to MLCC technology as people using modern SMD boards. The picture at the top of the article appears to show both leaded and surface mount MLCC, with an incorrect description. Most of the non-disk-shaped, leaded caps will be MLCC, especially the stair-step/up-down shaped ones. 76.105.216.34 (talk) 05:32, 20 January 2015 (UTC)


 * yes, I agree, MLCC is the capacitor internals, not the package. I own personally own MLCC caps in through-hole and surface mount.  •  Sbmeirow  •  Talk  • 13:40, 20 January 2015 (UTC)
 * In industrial datasheets it is common to use the term MLCC (Multi Layer Ceramic Chip) for the chip style in contrast to leaded or through-hole styles. The internal construction could be the same, with ot without leads. --Elcap (talk) 13:48, 20 January 2015 (UTC)

The images don't provide scale.
The images in this article don't give a sense of the physical size, especially for the SMT devices. They are OK if you already know the sizes, but not for a casual reader. There's no way to see that a 102 is the size of a sugar grain and a 603 is the size of a grain of rice. Can someone take a picture that includes something like a person's finger tip? On the other end of the scale, how big are the "doorknob" and "disc-style" power capacitors? In the middle of the article, there are four "styles" images in a row, all at different scales. The picture with the microprocessor helps a little bit, but not much, because not all readers are aware of the size of a microprocessor and microprocessors vary in size by at least a factor of 5 (linear). -Arch dude (talk) 15:15, 4 June 2019 (UTC)
