    Filter Cap R&R _ LG42 PDP 42x3

    Hi, does anyone have the parts list for this set?
    So far, I've only found a the Service Manual without the Parts List.

    I need to replace the Iron Inductor, (Filter Capacitor?) labeled as
    L1050 H A , 3/8" dia, x 3/4" long.

    at location L507 of the power supply board 782-ph42d8-2000
    I can't find any reference on the web.

    I'll also check the nearby components for failure as well.

    Any help would be appreciated.
    thanks, Sixstrung

      The letter "L" is the indicator for an inductor (a coil) not a capacitor. Capacitors are labled as "C" - and whatever number after that. Inductors usually (99 times out of 100) do not go bad. I have seen bad solder joints on a few but most likely you may have the indication of the component you really want to change mixed up. Take a picture of the board in question and the area. Post it here using "Manage Attachments" and you'll be pointed in the right direction for the fix.

          Thanks for the reply DG
          I removed the inductor because its sheath overheated and split wide open, either on its own or caused by the nearly touching, two 25v, 3300uF caps, or the F20JC10 transistor.... none of which show any deformation, leakage, etc.
          I can not find, or identify a replacement for the inductor.
          Can you suggest a direction to locate a replacement inductor?
          I'll chase the circuit for failures.
          thanks.

              I really couldnt tell you how to replace the inductor other than to find a service manual on the device and get a direct replacement from the original manufacturer.

                  It may not be necessary. If the inductor is a heavy gauge wire wound around a ferrite core, just put a piece of heat shrink tubing over it.

                  For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

                  Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

                      Thanks Bill, you are correct.... though I believe the heavy gage copper wire has a clear protective sheath on it prior to being wound on the ferite core.
                      Though I can't tell, I suspect that the wire's clear sheath melted somewhat when the inductor's outer wrapping melted.

                          Operating frequency for motherboard common mode inductor/filter
                          by J_T
                          I have a question - I have replaced the PSU on my own iMac Pro. However, when removing the motherboard I knocked of a 120 OHM 30% 0.3A small surface mount common mode inductor/filter (~0602 size) in the ethernet circuit near the female RJ45 port.

                          The closest match I can find on Mouser is 120 OHM common mode inductor at 100MHz - my question is this frequency correct for a motherboard? The schematic for the motherboard only provides '120 OHM 30% 0.3A' and the TDK part number does not return anything in google.

                          Sorry, I am not experienced hence a basic question.

                          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...

                          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.

                          Nvidia GTS 250M Laptop graphics - Inductor and Capacitor values
                          by rashidjafar
                          I am looking for capacitor & Inductor values for my TOSHIBA Qosmio X500-110 - mobile graphics - Nvidia GTS 250M Laptop.

                          Values for :-
                          =========
                          PC43 : Capacitor [3x1.5mm]
                          PL7 : Inductor [2x1mm]
                          PC39 : Capacitor [1x0.5mm]

                          Any ideas would be appreciated.




                          I can get Capacitor values from nearby components but wanted to know the max ratings also I dont have equipment to measure inductors....
