Hi I’ve searched digikey and mouser and haven’t found a direct replacement. All the donors i have (which are just 3)oddly have the same inductor damaged although the inductor works it’s just a eye sore. Does anyone have a direct replacement with the right size height and with or something close? Here are the specs DEM803C-SM 22uh 20% 2.4a 0.1050ohm.

Looks like I may need a little help from the PSU experts (or anyone really!
) I have a Corsair CX750M (Model 75-002019) that I picked up for free about 4 years ago. This is the PSU:
So here’s what’s strange about this one: it appears to work normally (normal output voltages) and any PC is stable with it. However, after a while (typically 10-20 minutes, but time can vary depending on the load), there is a sweetish smell of burned magnet wire insulation emanating from the PSU. Upon opening the PSU after this happened (many times), I was able to confirm... -
Hi,
I bought a used Marantz SR5007 and it's giving me some issues that I can't seem to really place. It functions well in most settings, ARC mostly works, it has no issues driving my speakers in any of the digital input modes, but I'm having issues running analog inputs in direct or pure direct mode. For some reason in this mode there's distortion for every volume increment I give it, but once the volume is stable it has no issues. Muting creates a loud pop, switching to another source also causes a pop and so does turning off the amp in that mode. Again, no issue in the digital modes.... -
Hi, i have a Lenovo S145 that after 20 seconds shutdown and restart (it's working correctly on thse 20 seconds)
everything seems ok, but on Vcore inductor ( this is an i3 with just 1 switching power supply for CPU)
there is an output to teh CPU with a spike.. seems that inductor can't handle the input...
replaced the capacitor (330) and the inductor (R15) without any change
any idea? very thank you!
input of the inductor seems as usual... only strange thing is that the upper/lower voltages seems to be 21V (main power line is 19.3) ... but not sure this... -
I have a broken samsung galaxy s10 with missing inductor. I want to replace the missing inductor and I have found some vendors. But I don't understand how to read the specifications of the inductor. The specs are:
INDUCTOR-SMD;470NH,20%,2520,T0.8,0.029OH
I understand that the inductor is 470 nH with 20% margin, and the size is 2520 or 1008 (imperial measure), but what do T0.8,0.0290OH mean? I can't find any explanation on the web. -
Hello guys,
I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.
I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...
