    as long as the esr isnt so low that the psu thinks it's an overload, it wont be a problem.
    this is obviously only going to effect output smoothing too.

    I still think low eSR caps are the way to go as even if though its a power supply Ina monitor its still critical
    To having it run correctly for a long time Japanese caps are the way to go

    budm, 56uF is much higher than 33uF. Also 0.14R may be too far off from 0.3?

    Nichicon PW looks like the best match so far.

    Thanks. The Panasonic FR is close, but I guess the ripple/impedance figures for the 35V version would be different at other voltages, so maybe it would be off with the actual voltage in use? But anyway, no stock.

    The Nichicon HE is actually an exact match. Didn't see it at first both because of bad data in the store parameter fields, and because the 50V version not listed in any store. 35V and 63V are stocked, but not 50V for some reason.

    Well, PW it is.

    You can use PANASONIC FM/FR series 56uF 50V with the same case size with only 0.140 Ohm Z.

    if you can get away with 35v then this maybe!

    By the way, something strange I noticed. The Samxon GF 50V 33uF is rated at 0.3R impedance (6.3x11mm case). I can't find an alternative that's that low for this capacitance. A Nichicon PW with 0.43R might still do, but am I missing something? No equivalent low ESR from other manufacturers? There's no 33uF for 50V in many series, 33uF 35V goes for 5x11mm so higher impedance, etc.

    They are more expensive than the KY series (pun intended) and Nichicon's PW series.... both are pretty good, but i have a soft spot for panasonic and hitachi caps, they are low esr which is what i chose it for you

    So far I see Nichicon PW for cheaper at 12.5x20mm, and NCC KYA and KYB for 10x20mm. Can you suggest other candidates?
    I have a preference for panny's caps so ill suggest this one LOW esr and my favorite FR series...

    this is for 1000uf and 25v

    and for 470uf and 25v

    Can I replace KME cap with Samxon GF cap?
    by chth96
    Hello.
    I have 29inch LG CRT TV,And Yesterday,Whenever I connect AC power cord to power outlet without switch on, I heard a sound like white noise, And When I switched on this CRT TV, It sometime displayed correctly But usually It won't last more than 20 minute and The screen begin to dark and It finally did not display at all for hours..
    Today,I dismantled its plastic case and discharged the biggest capacitor(400wv 470uf) which still holds 250 voltage,and I finally detached PCB from cathode-ray tube.
    I measured ESR value of most of caps in PCB with MESR-100 and I found that KME(25v...

    Decon SH PET Capacitors for “Klipsch The Fives”
    by brad2157
    I’m working on re-capping the power board caps on a Klipsch The Fives audio speaker system. I can’t locate a replacement for these original caps that are labeled “Decon SH PET”. I have three of these on the board with the electrolytics. They are supposed to be a film type capacitor, but they look like a radial mount electrolytic. Everything I find they look completely different, usually a square type body. The two values I need are 16V 470uF and 35V 47uF. I’ve got all the other caps in my cart already from Mouser, so if there’s a replacement there, I would prefer to order from...

    Old Boston Acoustics subwoofer repair, BJT alternatives
    by staze
    Working on an older Boston Acoustics HPS10SE, and while verifying voltages, I noticed one of the PSU BJTs is getting excessively hot and the voltage is dropping out on the 15V rail. Not sure that's actually an issue (I don't have everything plugged in, so maybe something is saturating on the positive end and dragging that rail down and the BJT overheating is cutting out).

    But, figure I need to buy some NP capacitors from mouser anyway, so might as well replace these. They're a H669A and H649A. Pretty "meh". They test fine out of circuit, but I can't really put a load on...

    Samxon capacitor esr
    by GEARELECTRONICS
    Hi all,
    I need your advice.
    -SAMXON 2200uf 50V tested 0.00 esr on Dick Smith Blue Esr meter and 2027 ohm on FLUKE 179 multimeter.
    -Is this esr reading realistic?
    Thank you

    Alternatives to Power-Z?
    by R7027
    Hello everyone!

    I am looking for an alternative to the Power-Z USB power meter, like the model KM001. Are there no alternatives to this? Other than other models from the same company? This is a very popular meter that repair pros use.

    I have a very simple and inexpensive USB power meter. I think it costed around 20 - 30 USD. I'm looking to upgrade it to one that has the logging and graphing functions like the one I mentioned above. Something in the same price range of 80 - 100 USD. Any suggestions?

    I actually have a DC power supply that has a USB port...
