Need replacement of NEOSID Ring Core

[Rleo6965]

Hi, This time I need your expertise finding equivalent of NEOSID 17-732-22 Ring Core 14.8X8X6.35mm. I think its now obsolete part.

I need this core as filter choke to avoid 22khz spike from center tap of push pull transformer going back to 12V Car Battery.

I have already build this dc inverter and working properly and I temporary use core from ATX PSU and wound 12 turns of 1 mm enameled wire to have 6.5uH filter choke inductance.

Now my problem was I need 10 pcs of equivalent or replacement of NEOSID core. After googling. I found out that NEOSID 17-732-22 have a Grade=2003, Saturation Flux Density=15,000 gauss and Max Freq = 500khz.

I search in RS and I don't know the equivalent MATERIAL to be able to search correct Ring Core equivalent basing those I mentioned above. I only need the correct core only.

As I mentioned before. I'm not graduate of any Electronic Engineering Course. I'm self study electronic engineer. This the reason I need your expertise.
