I mainly associate Molex with being a connector companen-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/experimenting-with-thermistors/b/challenge-blog/posts/thermistor-thermometerTue, 26 Jul 2022 22:44:10 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:433f7cd8-c088-47f5-89d4-6deebbae724dntewinkel1<p>Great to see you&#39;ve joined this challenge too, [mention:193ac2434c814a24b46635a2210baec1:e9ed411860ed4f2ba0265705b8793d05] !</p> <p>Looks like today might be a good day for me to test that the thermistors in my kit are in the right order!

Kit contains 21386<strong>0-1</strong>637, 21386<strong>0-2</strong>637 and 21386<strong>2-2</strong>637. While all three has resistance 10k@25&deg;C, there are still some differences. First two are from 21386<strong>0</strong> family while the third is from 21386<strong>2</strong> family (last digit is different). Difference between families is in characteristics. Family&nbsp;213860 has beta value of 3500 and family&nbsp;213862 has beta value of 3800 which results in different &quot;speed&quot; of resistance decreasion. Difference between two thermistors from 21386<strong>0</strong> family is in accuracy (21386<strong>0-1</strong>637 is 1%@25&deg;C and 21386<strong>0-2</strong>637 is 2%@25&deg;C).</p><img src="https://community.element14.com/aggbug?PostID=24029&AppID=377&AppType=Weblog&ContentType=0" width="1" height="1">
