    Help identifying ceramic cap in ECU

    Hi all,

    due to some bad soldering, the capacitor circled in the lower half of the picture needs replacing. No chance of getting a schematic etc of this car ECU. The only thing I can think of is desoldering the capacitor above, and measuring it's value? Then hope it is the same?



    Thanks!

      Re: Help identifying ceramic cap in ECU

      Sounds like de-soldering and measuring would be the best way.

      Just try not to overheat it or lose it.

      Of course if it's not in parallel with any other capacitor you might be able to measure in-circuit...

          Possibly the one above it is the same, but what's the part number of that big chip? Getting a datasheet/pinout would help ID what pin that is and thus what kind of cap would fit there.

              Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
              by sam_sam_sam
              I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

              One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

              Is it possible to test small ceramic disc capacitor with analogue meter?
              by chth96
              I read EBOOK of Testing Electronic Component and found that

              "In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
              Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
              It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."

              Reader PocketBook InkPad 3 ā€“ identification of a black component marked 'CT' on the microUSB line
              by Maniackk
              Hello,

              Device: PocketBook InkPad 3
              Mainboard: XRZ_E091_PB740-VTTOA-V1.1 / 2017-10-12

              I'm replacing the broken microUSB connector on this e-reader, and during inspection after desoldering, I noticed a loose black SMD component marked "CT". One of them was torn off along with the pad, while the other one (marked in the photo) is still in place.

              I would appreciate help identifying this component.

              Measuring the loose component with a multimeter gives 5.84 MĪ© in both directions, while the one still on the board shows no measurable...

              HP EliteBook 840 G6 how to dump without desoldering
              by hans_meier
              Hi,

              I have an "HP EliteBook 840 G6" and would like to know how to dump the BIOS flash chip without desoldering. Putting 3.3V on VCC of the BIOS chip with a programmer does not work (seems to enable the PCH). I have read some general notes about connecting the CPU reset to ground or to bypass oscillators. There does not seem to be a reset line for Intel i5-8365U. Just RSMRST, but it's only accessible on the other side of the mainboard. Is there an easy way to dump the flash without desoldering and without removing the mainboard? Does anyone have experience with this? Maybe...

              ISL95880HRTZ desoldering temperature
              by Dreigas
              Hello,

              I bought from China ISL95880HRTZ (3+1+1 Voltage Regulator with Expanded ICCMAX Register Range Supporting IMVP8 CFL/CNL CPUs) chip, which I think is not the original one, but anyway, I tried to resoldering it with a 380C hot air station. Seems soldering is pretty good, but the laptop doesn't work (it worked before, but still had some problems with power delivery).
              Is there any big chance, that they sent me two fake ISL95880HRTZ chips or did I just use too big temperature for desoldering? I will try with another chip, but I can't find any info about the maximum desoldering...
