Hello,

                Customer meet a temperature drift issue of LDC. They read out L value and it varied on different temperature. Below is inductor they use. Do we have any suggestion for temperature compensation? Thank you.

    Hello Patrick,

    If there is any physical size change in the inductor due to temperature, then the inductance can shift with temperature. If the inductor has a ferrite core, you may also see a change in permittivity with temperature. Either or both of these effects could be present.
