    Looking for information on Metallized polyester Film capacitor.

    Hi
    A metalized polyester film capacitor on my equipment is dead ... time for me to ask what the specificities of this technology... I read that metalized polypropylene film have better reputation…
    Also AR is written on the component, I suppose that it is the manufacturer name?
    Any information welcome!

    Lelon versusTeapo/Luxon

    Hi,
    Does anyone with experience on Lelon and Teapo could advice which one is better?

    ESR meter

    Hi,
    I am looking for a capacimeter / ESR meter. The following :

    [url]http://www.peakelec.co.uk/acatalog/jz_esr70.html[/url]

    Compare to some other ESR meters, which sometime doesn't even have a display, it looks fine and at a competitive price. Best on the market?...
    Any experience on it? Worry a bit about accuracy…
    Thankshttps://Hi,<br /> I am looking for ...e doesn't even

    Just a bit surprise that an important brand like Dell use CapXon capacitors in its PC.... I would guess that, as their PC are used by professional, Dell would select more carefully its supplier...

    Re: Luxon?

    Hi PCBONEZ.
    As you wrote
    “I can't say for sure that's where the name came from but I'm confident Teapo and Tayeh came down the same assembly line after seeing Tayeh branded caps with Teapo trade mark vents.”
    Could you explain what the Teapo “trade mark” vent is? How to differentiate from others vents? Any information on what is wrong (bad electrolyte?)... What we see is that some months production are not too bad, some are awful...

    Re: Luxon?

    Not a respond to your question, but for information Luxon and Teapo are same Taiwanese manufacturer for a few years now (see internet).
    We had huge problem of bulged capacitor from both brands, to avoid 100%.

    Re: Capacitor lifetime

    Thanks a lot for the clarification, KeriJane and Shadow.
    “Get the biggest number that you can afford” and “Stick with a reputable brand and give it moderate conditions to operate in” are quite pragmatic rules. (Unfortunately in consumer design these are not always followed)

    Capacitor lifetime

    The more I look at the capacitor, the more puzzle I get. First we could expect to find the life time of the component in the datasheet, but what we finally get? 1000, 2000, 3000, 5000 hours! That is from one to eight months!!! A colleague explains to me that this figure is calculated in the worse condition, of course working condition are not so bad so the expected life is much longer… Hum, I may miss a point but I don't really care that I can use a capacitor during six months in the worse condition, all I care about is how long it will last in nominal configuration. There I got the explanation...

    Date code

    A colleague told me that date code are year / week of the year.
    Teapo looks more like Year / month to me, I didn't see any second value above "12". But now I got a doubt, could someone help?
    Also I didn't manage to find a single TEAPO datasheet on the internet... Any idea (link) where they are available?
    Thanks

    Re: Test caps on board ?

    I was not aware of specific ESR meter, so I just had a look at B Parkers ESR meter. Any idea on the principle behind this? I think it send a frequency on the board...
    On the board, in parallel with the chemical capacitor I need to check, there are 6 x 4,7 nF CMS, from your experience do you think it should still works...
    Thanks a lot for your reply!

    Test caps on board ?

    Hi,
    New on board, hello to all from France.
    Here is my problem. We got huge number of products with faulty capacitors. Here we speack about filtering capacitor (supply 3V3, 2V5, 1V2 to CPU). They are Teapo and Luxon (2006 production), 100 / 470 UF, 105 degre. First, is there a way to check a capacitor on the PCB, without removing it (save lot of time...)? I tryed with a capacimeter, but as it measure the time to load the components to find its value, its works fine when this component is not on the PCB, but not at all when the component is mounted on the PCB. Maybe there is other...
