Ozone Chebyshev filter

Posted 18th April 2014 at 03:39 AM by abraxalito

I've munged the earlier 8 inductor filters down to only 5 - this one is using off-the-shelf TDK inductors, SLF7045-681, albeit they need to be hand-selected to get the correct values as the production tolerance is 20%. X7R caps sound just fine, surprisingly

FR is -3dB at 17,8kHz with around 0.25dB of passband ripple.

    No, the -150 variant of this inductor looks to be 15uH, it certainly won't work.
