Hi

I am working on a wireless power receiver design (Qi compliant)

As part of design I need to measure Inductance of my receiver coil @ 100kHz / 1Vrms (using the test setup as explained on page -29 of of following document)

https://www.ti.com/lit/ds/symlink/bq51050b.pdf

The coil I am using is:

From Wurth Elect


In order to do this I need a LCR (or Inductance meter).

I have seen some online LCR meters (like from Peak Atlas, Tenma, etc)

But it looks like they have fixed test frequency and 100kHz is not there also not sure about 1V either

Do you have any suggestions for good handheld LCR meter preferably < £500 that would help me to do the above measurements (and also for other inductance in case I end up changing the coil like in range of 5ish uH to 50ishuH at least)
 

The inductance doesn't change with frequency or voltage, excepting that some resistive or parasitic parameters may change a little. You can use any LCR meter. I use one that cost < £10 from Ebay that also tests transistors and ESR. Search for ESR or LCR meters and you should find one.

The PDF for the inductor says 7.5uH, look at the top of the chart.

Brian.
