Capacitor identification 2

"Peter Hucker"

Suitable for connection across active and neutral .

Removed from a broken (caught fire!) fanless power supply (fanless PC power supplies are NOT a good idea - Yesico was the manufacturer if you want to avoid them).

It was right next to the AC input, so I assume it's a filter capcitor (to remove high frequency noise?)

It says on it 0.33uF, and my multimeter agrees.

But, when I tried to use it in a circuit to limit AC current, it did not limit. I expected it to limit the current twice as much as a 0.67uF capacitor which I had in the cirucit previously. It limited it a lot less, as it blew stuff! Replaced blown components in circuit, then put this thing in series with the original 0.67uF cap. It did not affect the current at all.

Is there something other than a capacitor in here?

Ohmeter shows infinite resistance both ways.

BTW

The lack of LHS indent markers with your post is bad usenet practice.

Fix it.

It is a specialized cap specifically for AC entry filtration.

I expected it to limit the current twice as much as a 0.67uF capacitor which I had in the cirucit previously. It limited it a lot less, as it blew stuff! Replaced blown components in circuit, then put this thing in series with the original 0.67uF cap. It did not affect the current at all.

resistance both ways.

The construction of a capacitor will determine the applications for which it functions best. It may also read fine at low voltages but leak straight through at some higher (a mere few volts even) voltage, if it has been breached (read dielectric piercing), that is.

Good answer, but will you ever learn how to post properly in Usenet?

limit. I expected it to limit the current twice as much as a 0.67uF capacitor which I had in the cirucit previously. It limited it a lot less, as it blew stuff! Replaced blown components in circuit, then put this thing in series with the original 0.67uF cap.

So you hooked it up in series with for example a 500W load and the load drew full current?

I guess that could explain the fire :)

My post was the original in the thread, there are not meant to be indent= markers you twit. It is YOU who failed to indent what you quoted from = me.

not limit. I expected it to limit the current twice as much as a 0.67uF= capacitor which I had in the cirucit previously. It limited it a lot l= ess, as it blew stuff! Replaced blown components in circuit, then put t= his thing in series with the original 0.67uF cap. It did not affect the= current at all.

Ah, maybe it's broken then. The fault with the power suply was at the o= ther side of it though, a couple of 2 watt resistors look to have overhe= ated, causing meltdown of quite a few surrounding components.

Har har. Actually 15mA.

That is a VERY RARE event.

It MUST be your software.

....... Phil.

Yes there are. I indented the "see if it explodes line", which can stil= l be seen above, indented one more level than my "what?" However you fa= iled to indent anything at all.

ROTFPMSL! So when YOU make a reply with YOUR software, you claim it's m= y fault somehow? All your software has to do is take the text of my pos= t, add markers to each line, then let you add text unindented at the end= . Not very hard is it? I bet you're using Outhouse Distress [checks he= aders] OHO! I was correct. Now how did I know that?

"Peter F***er"

Yes there are.

There is none above these very words.

ROTFPMSL! So when YOU make a reply with YOUR software, you claim it's my fault somehow?

YOU F****NG TENTH WIT !!

Hope that stupid X cap blows up in your ugly face.
