    Is this inductor still usable?

    Hi all,
    I found this inductor in a server power supply and I am unsure if its still usable.
    First I thought its an exploded diode, but when I removed it I saw the designation L on the PCB and after asking on discord it turned out its a inductor. How ever... it looks to me like its a wrap of thin layers of some material and its flaking off on touch. Also the area where it was, all the components there are covered in some white powder.. like there was an explosion going out from this inductor.
    So the question is... is this still usable, and if not... what kind of inductor is this and where do I get a replacement?
    Its coming from a server power supply.
    Power-One: HB-PCM01-580-AC

    I am a complete beginner at electronics and just playing around with repairs for fun... more to learn then anything really. Every information is welcome!!

      It is likely ok, I suspect it is basically just a piece of wire with a ferrite bead attached, there was likely some type of coating on it but it should not effect its operation.

              it looks like a ferrite bead actually

                  Corsair CX750M [Model 75-002019] - burned output toroid inductor
                  by momaka
                  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...

                  Troubleshooting of redundant F750E-S0 Dell PowerEdge Server
                  by omega
                  Hello all,
                  as a beginner electronics hobbyist, after a few years I would like to place another post on this Forum section, given that I did not succeed in finding any useful advice among the other posts.

                  Over the last years, I have been using a PowerEdge Dell Server with two redundant PSUs, namely the 750W F750E-S0 ones (aka 06W2PW). Unfortunately, last summer one of them failed (perhaps owing to an overheating), and the server had for working to take into account the other one only. Of course I opened and tried to troubleshoot the failed PSU, but each cap I tested seemed to...

                  Lenovo S145 -15iwl vcore inductor warm.. looking with oscilloscope there is a spike.
                  by Bartoloni
                  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...

                  How to read inductor specs?
                  by badcap111
                  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.
