Increase list[edit]

Unless anyone objects, I would like to increase this list beyond the standard given. Pi.1415926535 (talk) 11:03, 23 May 2008 (UTC)[reply]

If you mean adding more elements to the list, remember you will still need to supply verifiable references to indicate their validity. CultureDrone (talk) 09:57, 17 June 2008 (UTC)[reply]

Verifiability[edit]

I'm a little concerned by the phrase "The table below lists designators commonly used, and may not comply with the standard." - which ones don't comply with the standard, and why are they listed with no additional references cited ? CultureDrone (talk) 10:04, 17 June 2008 (UTC)[reply]

The problem is that the IEC standard is quite expensive and not openly available. It would be really nice if someone with access to the standard could point out the main differences, and as much information as possible without breaking any copyrights. —Preceding unsigned comment added by 88.90.51.65 (talk) 19:51, 11 September 2009 (UTC)[reply]

merge[edit]

I suggest pulling the reference designator lists out of electronic component and circuit diagram and merging those lists with the list at reference designator. Also leaving behind a pointer to the merged list. --68.0.124.33 (talk) 05:51, 24 December 2008 (UTC)[reply]

Components commonly designated YC[edit]

Anybody know what these usually turquoise blue colored devices are that usually look like fat ceramic capacitors? I don't seem to be able to find out without having to purchase a data sheet. 1812ahill (talk) 18:20, 25 August 2009 (UTC)[reply]

Sounds like a ceramic resonator to me - a ceramic version of a crystal oscillator, often with load capacitors built in and 3 legs. It could also be a "Y" capacitor, with a separate in and out lead to reduce impedance (but then it would probably be named CY). Note that most designers (that I know of anyway, including me) don't use the "standard" designators rigidly, each company may have their own internal standards (eg LED, IC, RLY) which a designer quickly learns when they start work, or makes up as they go along... So there is no way of knowing for sure. Adx (talk) 12:18, 21 September 2009 (UTC)[reply]

If you're still wondering varistor would be my best guess... but I hope you've found your answer by now 1812ahill Mattman00000 (talk) 23:16, 31 December 2015 (UTC)[reply]

Zener[edit]

"D Diode (including Zeners, thyristors and LEDs)", "Z Zener diode" So what is the zener designator? Or it is dependent for the application? (Zener stabilizer is Z and voltage limiter is D?) And the suppressor diode (TVS)? U is the Unit?--Csakegyujonc (talk) 11:43, 12 April 2015 (UTC)[reply]

Wrong article linke in German Wikipedia[edit]

"Betriebsmittel" is not the right link - there is nor matching article in German Wikipedia at all. — Preceding unsigned comment added by Kiu77 (talk • contribs) 17:27, 28 April 2019 (UTC)[reply]

Removed coupling from WikiData. --Ajv39 (talk) 23:24‎, 28 apr 2019 (UTC)

Other standards[edit]

The IEC 750 Item Designation in Electrotechnology is another standard for reference designators. IEC 750 (IEC 60750) is used by e g some electronics industry companies in Sweden and Germany. It conforms with IEEE 315-1975 on a few items (assemblies, resistors, capacitors, inductors, relays) but is generally quite different. For instance, it distinguishes between analogue and digital elements (ICs) (N and D, respectively). Transducers = B; tubes, semiconductors = V, etc etc.
