Wrong Reliability Calculation?

edit

In Reliability section, FT = temperature acceleration factor, for T = 40 °C is FT = 0.1 doesn't match 10^(To-Ta)/20 rule. — Preceding unsigned comment added by Chungexcy (talkcontribs) 00:19, 21 December 2015 (UTC)Reply

Reliability and life time are two complete different things. Reliability (failure rate) calculation comes from MIL-HDBK 217 and defines the number of failures per time related to the temperature. Life time calculation depends on degradation of electrical parameters related to temperature. The formular given comes from manufacturers assuming, that no failures occure. --Elcap (talk) 13:06, 22 December 2015 (UTC)Reply

Wrong Formula?

edit

The Formula listed under "Lifetime, service life" seems to be wrong and does not fit the presented results. The references (Nichicon) give 10^(To-Ta)/20 which looks better. — Preceding unsigned comment added by 84.63.200.193 (talk) 20:45, 2 October 2015 (UTC)Reply

sorry, writing mistake, formula corrected, thanks.--Elcap (talk) 16:25, 3 October 2015 (UTC)Reply

Silly

Where in the construction is that "polymer"? — Preceding unsigned comment added by 93.221.213.217 (talk) 09:41, 20 March 2013 (UTC)Reply

Working voltage up to 35 V ???

edit

It is said in article that working voltage of polymer capacitor could be up to 35 V. Is it individual capacitor or an array? If sole capacitor then could they give a ref. which proves it?

Hi, Panasonic OS-CON (an ealier brand from Sanyo) have rated voltages up to 50 V, see: New OS-CON Capacitors, Aluminum-Polymer Solid Capacitors; Panasonic [1] --Elcap (talk) 17:43, 23 November 2013 (UTC)Reply

Request - Rectangular Case Size

edit

This article needs a section for "rectangular chip case size", similar to Tantalum_capacitor#Chip_capacitors_.28case_size.29. • SbmeirowTalk18:28, 13 December 2015 (UTC)Reply

nice task, Al- and Ta-chips case sizes in one table. For the cylindrical case sizes, too? Give me some time.Best regards --Elcap (talk) 14:34, 15 December 2015 (UTC)Reply
I'm sure it won't be easy, so it's your call. It appears that manufacturers make part that meet the standards, then maybe some other parts that are unique. At a minimum, the industry standard sizes should be on the table. • SbmeirowTalk12:44, 16 December 2015 (UTC)Reply

E-cap?

edit

Is "e-cap" a common abbreviation in English? I have not come across it before and it doesn't seem to be widely used (except on some Asian websites). Thirteenangrymen (talk) 09:24, 24 July 2018 (UTC)Reply
