Replacement NTC with narow transition region
« on: January 21, 2021, 05:21:32 pm »
Hi to everyone,

on the bench i have a board which uses Moxie TS3-75 for the temperature protection. It is a NTC in a TO18 package and has a very narrow transition region around 75°C. You can see in the attached datasheet. The NTC is faulty as it is floating around 35kohm at room temperature. Should be at around 300kohm according to datasheet.
I also included a picture of the NTC desoldered and how it is squeezed against a heatsink, so you can see how much space is there for improvisation.

The problem is that i cannot find an appropriate substitution for it. Any idea?

ebay Germany:

(Noticed he does only ship to Germany; so you need to ask him about shipping - should not be that hard I guess...)

Thanks for that! I did send him a meassage if he would be so kind to send it here, we will see.

It is strange that if i search "TS3-75" on ebay.de, i get 0 results... I can only see this item with the link you pasted

ebay hides items that do not ship to your country...
