 # Deprecated Options
 
+###### NTC 100K beta 3950
+## Removal of `NTC 100K beta 3950`
+
+The "NTC 100K beta 3950" temperature sensor is _deprecated_. This sensor will be removed in the near future.  
+Most users will find the "Generic 3950" temperature sensor more accurate.
+
+To continue to use the older (typically less accurate) definition, define a custom thermistor with `temperature1: 25`, `resistance1: 100000`, and `beta: 3950`.
