    Looking for help identifying the rating on this thermistor

    I believe it's a 2.2OHM based on reading the other ones with the same markings. Just wondering if anyone knew for sure what it was. Thanks.

    Does the resistance increase or decrease as you warm it up?

    "2407" is probably a YYWW date code.

    I would have thought that "005" would be the resistance in ohms at 25C.

      The closest image I can find is this with the similar numbers 125 003, it is listed as Ametherm Thermistor SL22-2R510, (STI: 125 003) Inrush Current Limiting
      Measure the diameter of yours or provide a make and model of what it is used in

        The part marking is obscure. I can't understand how anyone could make the connection, especially since the datasheet is devoid of this information.

        Nice find, by the way.

          Can not find Model/Value of Thermistor.
          by nmbb
          Machine: Autoclave.
          Brand/Model: SANYO MLS-3780
          Manual: (Sorry search option not working on this PDF)



          Hello guys, this autoclave running with 2 thermistors already connected TH1 and TH3(on CN1,CN2 sockets). One for the water temperture and second one for chamber temperature. But there is another emtpy socket for optional third thermistor CN2 wich is for TH2 for object temperature. I wanna add the third thermistor TH2 to CN2 socket. But i can't figure what model/brand/value i need to use. In manual document, there is no info about TH1 and TH3 model number...

          I need help identifying this thermistor
          by Assurance
          Hi all,

          sorry if this has been posted in the wrong group

          Im trying to replace this thermistor<<<10D-9 >>>> implies 10ohms, 9mm
          im not sure if this NTC or PTC ?

          I need help identifying this thermistor from
          rs online website and
          https://uk.farnell.com/w/c/circuit-p...ost=thermistor


          what will this be an ideal replacement fro RS ?


          Ive been chatting with RS online but theyve been very unhelpful...

          Is it no harm to replace with capacitor without ripple current rating?
          by chth96
          When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


          Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
          But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
          Rubycon YK DataSheet (b...

          Magic chef oven - thermistor ref voltage issue
          by Use2bavolvo
          I am having an issue with my wall oven temperature control is ~180f out of spec. The thermistor is measuring correctly but I noticed the ref voltage appears to be off. With the thermistor wires attached it's reading ~3.4vdc with the thermistor disconnected it's around I9.8vdc. my understanding is the temp is read off the resistance from the thermistor which leads me to believe the issue is with the ref voltage.

          Another observation is the temp setting and readout at lower temps is way off meaning the oven thinks room temp is 300f and bake relay doesn't engage unless temp setting...
