Current rating IN: The current rating of the inductor is specified as the DC current at which inductor exceeds the permitted tolerance limits (DL) or the self generated heating (DT) exceeds a certain limit. The smaller of the currents defined by the two conditions is termed the current rating of the inductor. This is how ever not the saturation current, which is higher than the current rating.
While that datasheet doesn't show inductance v. temperature, it does show inductance versus current. Here's a further discussion: https://ec.kemet.com/wp-content/upl...-Capacitor-Inductor-Fundamentals-Final-v2.pdf
Edit: From another source:
Thank you much. My setup is a low-pass filter. I need to know how the inductance changes along the day with ambient temperature. Then, I could calculate the changes of time constant of the filter along the day.
Source: https://www.coilcraft.com/getmedia/...9886d68c1/doc1287_inductor_specifications.pdfTypical wire-wound air core and ceramic core chip induc- tors (non-magnetic) have a temperature coefficient of inductance (TCL) in the range of +25 to +125 ppm/°C. Inductors with ferrite cores will have more variation, with temperature, with TCLs up to 700 ppm/°C or higher.
