NTC thermistor

[multimeter]

hi guys long time no see

currently repairing a samsung bluray player with a blown NTC part no,NTC3D-9 due to a suspected surge,all surrounding components test fine,bridge,caps,diodes mosfets etc..

the NTC is a 3 OHM 4 AMP,im un-able to find the exact part number..

i found a 3 OHM 5.4AMP NTC from RS components,my question is will the higher amperage NTC cause any problems?,and what is the function of the amp rating of the NTC?,does it limit at 4AMP the current going into the power supply?,or is that the max rating the NTC will take before destruction?

cheers guys hope you are all well

Edit! just read thats a pulled used part so maybe best to go with the rs part im sure budm will advise if the part you have chose is ok.

Re: NTC thermistor

It will work fine, it just means it can handle a bit more current than the original, when the unit is working all the current of the unit must flow through it so it has to handle at least that amount of current, going higher is not a problem.
