Talk:Reservoir capacitor

Filter capacitor is a short, three-line stub article which talks about reservoir capacitors used in power supplies, with a brief mention of filter capacitors used as part of an electronic filter. For this reason, I suggest either merging it with Reservoir capacitor, or perhaps replacing it with a disambiguation page.

The subject of filter capacitors for power supplies is vastly more complex than just a reservoir of energy. This page needs some meat to it. There are several books on the subject and it should be possible to quickly capture the essence and make the page worthwhile. I will put it on my list....  If not done by 8/30/07, then merge it.


 * I AGREE. Both articles are short and it wouldn't do harm to merge them. They are about the same thing.--Iamcon 01:42, 17 October 2007 (UTC)

DISAGREE, filter caps and reservoir caps are quite different things, and there is plenty to write about both. Given time these will become 2 full articles about 2 different things.

DISAGREE, keep them separate. In addition to the considerations in the previous post, they are mostly physically different -- large electrolytics are seldom used purely as filters, and small plastics are rarely used as reservoirs. Clearly their nature as capacitors enables both behaviors, and clearly there is a sense in which a filter capacitor "stores" and a reservoir cap "filters", but the applications are distinct enough to warrant separate articles. 68.227.15.115 (talk) 22:41, 23 January 2008 (UTC)

Resistance
The 2nd diagram assumes zero impedance source, which is good for an initial explanation, but IRL transformers have significant resistance, whch complicate matters quite a bit. I suggest we therefore need a 2 stage explanation, first for the simplified case, then in more detail for real world designs. Tabby (talk) 00:35, 12 January 2008 (UTC)

Done and redone - though with room for more depth on the resistive source one. And we now need a pic for that too. Tabby (talk) 13:52, 17 February 2008 (UTC)
