    Help identifying a blown cap

    I'm new to the forum and not much of an electrical whiz. I run a small WISP in Utah and I use Mikrotik/Routerboards all over my network. They are great devices with horrible capacitors in them. I have had this problem when the boards are powered with a wall wart as well as POE, indoors and outdoors. I've tried contacting Mikrotik regarding the capacitor problem but have not gotten far. I'm hoping to find some answers here. I have pictures of the capacitor and one of the offending boards. I am looking for two answers.

    1. why do these caps keep failing?
    2. What cap would be a better choice for replacing the blown ones.

    Welcome to Badcaps!
    Quick answers (I'm suppose to be working...)

    1 - Su'scon are absolute crap caps.
    2 - Panasonic FM series.
    36 Monitors, 3 TVs, 4 Laptops, 1 motherboard, 1 Printer, 1 iMac, 2 hard drive docks and one IP Phone repaired so far....

      And don't forget to crack open the wall warts too.

        The Su'scon is a 560uF 6.3v capacitor. You can replace with 560uF 6.3-16v capacitors (capacitors with bigger voltage rating can be used with no problems at all)

        Replace with Panasonic FM or Panasonic FR series capacitors.

        FR series handle heat a bit better but even FM would be much better than what's used now. As mockingbird says, double check the wall warts as well.

          Thank you for your quick replies. I can't check the wall warts. They're at the metal recyclers.

            What are you going to use instead?

              If I use it for a point to point I'll inject power.

                Lightform LFC mini PC,Blown Component - Need help identifying or Next Steps
                by silver60618
                Hi gang, I have 2 of these Lightform LFC mini PC's, and both suffered a blown component near the 12V power input. Im assuming its a voltage regulator,
                But Im unable to identify the component or its marking. (The best I can make out is M48i)

                Can anyone help me clarify what this component maybe? or what would be the next troubleshooting or logical step to try next? Schematic is unavailable

                I removed the IC for better clarity of traces...

                Samsung U32D970 PSU blown up (Identifying Parts)
                by Fr3shGy
                Hi, my U32D970 PSU (BN44-00786A) has blown up. It went out with a loud bang.

                One of the N-Channel Mosfets (OM802C) caused a short and fried the trace and its components connecting to one of the pins of the 6A01 IC.

                I need help to identify 2 SMD resistors which lost their markings
                highlighted in picture 3 (RM812 and RM808).

                Maybe someone can help me identify them, has a schematic or can give me some advice. would be much appreciated.

                LG 47LB5DF blown power supply board
                by cmlewis89
                Hi folks,

                I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown...

                HP X360 convertible battery blown fuse error, not charging
                by drscoot
                HP Modelnumber: 14-dh0061nb​
                This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
                The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
                I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
                And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)
                All these 3 batteries are charging...
