DCR of Inductor Models (Coilcraft)

jonnybgood

Hi, 

I am trying to see the effect of the DC resistance in the inductor models by connecting them to a current source or voltage source and see voltages or currents in time domain. According to the datasheet of the 0402CS-10N , it should have 0.2 Ohms DC resistance which at 100mA should give me at least 20mV. However I am only seeing -600uV which seems to be meaning less.

 Is there a specific way to simulate this? thanks

    Capture CIS PSPICE and in simulation settings I leave everything default and in time domain.

    I moved this to the PCB Design forum, because you're more likely to get an answer there. The RF Design Forum tends to be IC-based RF Design (e.g. SpectreRF as the simulator).

    Regards,

    looking at the Model it appears that inter DCR value is set to 0.006 ohms, hence you are seeing such result. This model is supplied by coilcraft. You may want to edit the model and change this to be in sync with datasheet value (0.2 ohm instead of 0.006 for R_R2)
