    Re: Post help identifying capacitors here

    Wondering if anyone can help identify this component.
    It is out of a Yamaha Golf Cart charger JW9-82107-03.

    My best guess is a capacitor of 2200pF, or some sort of varistor. I can not find any info online for the marking. It reads a resistance of 3.5 ohms and causes the fuse to blow when in circuit. It sits across a relay contact on the 120V AC side before the main input capacitor. See Pic.

    Thanks!

    About the ripple current, for computer motherboards, computer PCI cards, etc, is lower ripple the most desirable? I mean, doesn't that give you a cleaner signal?

    Is ripple always related to height? more height = higher ripple?

    Thanks for bearing with me.
    I tried "Nichicon LF datasheet" as a search result since Nichicon is a large brand in the Aluminum Polymer capacitor space. However, you would be able to get to the same datasheet by searching "LF Polymer Capacitor Datasheet". The format of the capacitor code also made me think it was Nichicon (you can get an idea of the formatting by looking at the non-FPCAP Polymer Capacitor Datasheets on here [e.g. Nichicon [polymer] CF series.pdf ]).

    The key with ripple current capability is that it is ripple current capability. This indicates how much ripple current the capacitor can handle in the input, not how much ripple current is in the output. Bigger capacitors of the same capacitance and voltage in the same series can generally handle more ripple than smaller capacitors of the same capacitance and voltage in that series.
    Let ne know if you have any further questions.

    From the LF and a little bit of searching, we can find out that this is a Nichicon LF series capacitor (datasheet here).
    When we look at the datasheet, on the first page under "Dimensions" we can see a breakdown of the meanings of the markings on the capacitor. From the "voltage" table next to the markings explanation, we can see that an "e" voltage code signifies a 2.5 volt capacitor.
    Now we can look at the second page with "Standard ratings". You can determine the exact capacitor you have by measuring the height with calipers or a ruler. Depending on the dimension, you will be looking for a replacement Aluminum Polymer capacitor with (9mm height) an ESR of 7 miliohms or lower and a ripple current capability of 4800 miliohms or higher or (12mm height) an ESR of 6 miliohms or lower and a ripple current capability of 5700 miliohms or higher. Let me know if you have any additional questions.

    " LF 680 e 672 " (e or 0?)

    I think this one is 680uF but what is the voltage? And how do you guess? Diameter is 7.8mm

    It's a smd capactor 560 picofarads or 0.56 nanofarads , 50 volts . Better test capacitors outside the donor board . Try find similar size and test it .

    Thanks Per Hansson and jiroy!

    I thought maybe they were inductors but I wasn't positive. I have one that is discolored, so much so that the marking is almost unreadable, and the ferrite "cap" has popped off so I'm pretty sure it needs to be replaced. I attached the above pic because the markings were clear. These are in a Samsung surround sound amp/cd changer. I'll order a few and replace the one that's lost its head and see what happens

    Thanks again!

    Re: Post help identifying capacitors here

    Those are discrete Through hole ferrite shielded radial choke inductors , and like Per Hansson mentioned , no need to replace , and they look super fine .
    About the marking , 1310A stand for 13mm x 10mm , A for tolerance 5% , and 1510A stand for 15 mm x 10 mm , A for tolerance 5% .
    Without labeling them with their inductance values , like mh inductance , makes them standard from any series from some unknown company . So the only way to know their real value , without a schema is to measure one of them . Next , you can have any similar 1310A , meaning 13x10,5% , from any other manufacturer , like this series attached , SRC1013 .

    Re: Post help identifying capacitors here

    Hello!

    Can anyone tell me what these are and where to buy replacements?

    Marked 1510A and 1310A

    I have Google searched but haven't had any luck locating any info.

    Thanks in advance

    Here is the component on the back of the socket:



    I removed it to be sure that it being desoldered would not damage anything else.
    That's a smd ceramic capacitor , basically to provide power and stability to the CPU . Measure any surrounding capacitor , they're basically the same here .

    For the BA5P03 , I need more , including height and even the pins ..

    The unidentified component seems to be 3mm * 6mm. It's a bit tricky to measure, because it's between two PCI-e ports and the two capacitors, but I think this is the right measurement.

    Need help identifying capacitors on an MSI MS6163 ver 1. motherboard
    by varkatope
    Hey there, retro fans.

    I have an MS6163 version 1 board I'm trying to repair which was obviously used as a donor because it's missing a few parts, mostly capacitors. There are few high quality images online that would allow me to read the capacitor values (bad angle, blurry photos). I thiiiink I've figured out most of the values for the missing ones except for one in particular, number C210, which is in the bottom-left of the attached photo. Could someone with this board be so kind as to take a look at theirs and tell me the capacitance and voltage values of all the highlighted missing...

    After updating motherboard capacitors, what to do next (Asrock K7VT2, SOLTEK SL-75FRN2L)

    AA and AAA battery charger capacitors?

    hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
    it has inside:
    2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
    2 x 470uf 16v LZ105c branded as G.Luxon
