    Resonator - quartz broken - how to find the same (same frequency) ?

    Hello, I have a Fujifilm hybrid camera with an issue : the time don't run. I set 12:00 and 3 min later, the same : 12:00
    I saw an obvious root cause : a broken quartz (resonator). But with the box broken, I can't read the marking code. Probably : 464… or A64…
    I found on the web a picture of the same camera board but with marking code very different. Probably : A7…5N
    I'm searching another one for compare…
    Do you have an idea or another way for find the frequency of this resonator please ?
    (I did not found the manufacturer of this component ? And I did not found the chip).

    It's probably a Seiko-Epson 32.768 kHz crystal.

      Yes, you found it, exactly this one.
      And now I saw why marking codes are so differents : only the first letter « A » is usefull.

      Thanks you

          Is it possible bridging tiny broken trace
          by chth96
          When I assembled dreamcast I mistakenly fastened long bolt and It resulted in
          cutting tiny trace.
          This tiny trace(Total width of white coating is 5.5mm) is between R337,R343 and IC101 and it is covered with white coating in the below screenshot.


          Firstly I tried to bridging tiny broken trace with my own eyes...But it is totally impossible..So a week ago, I ordered G1200 Digital Microscope and I magnified this tiny broken trace with it.

          But It seems that It is really very tiny trace So I plan to order 0.1mm coper wire from aliexpress in order to bridging...

          Where to find a very small fpc connector 0.3mm between 2 pins ?
          by corrize
          Hello, I search this connector (oxydated).
          It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
          I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
          I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?


          Do you know how to find this connector please ? What is the exact name for find it ?

          by sam_sam_sam
          This Dell computer is a pain in the a** because of it only has one memory slot this computer only had 4 megabytes of memory and slower than shit I found a 8 megabyte memory module and it is better but still slow as shit the maximum is 32 megabytes of RAM but I was not able to find one I found some that are 16 megabytes but they are 1600/128000 type and I am not sure if this computer will work with this type of memory or not

          Dose anyone knows where I can find a 32 megabytes memory module for this computer because the battery still works fairly well still I would like to use it on my...

          Sentey ATX PSU - ERP650-PS - Trying to find out the right Standby IC
          by temyth
          Greetings! I have this ERP650-PS atx power supply, it is a relatively simple psu, the primary has a driver IC that controls the two main mosfets (two 20n60S5), together with a Classic Standby circuit with a PWM IC (not a FET like the VIper22A) , relatively similar to the SDC606P.

          The whole point is that I got this power supply years ago when I had no knowledge, apparently the PWM IC was burned because someone turned the power supply on with the switch at 110v in a 220v network (classic error). Important detail: the power supply at the time came without the primary capacitors.
