With just a photo we cannot determine topology requirements, turns, or materials to hand you a definitive number. Perry *may* recognize the PCB just by looking at it and might have that information handy for those specific inductors.
However, without stating your intentions he and others might be hesitant to give you a figure that say, might not work for your intentions. If you are building a class D amplifier stage and have a schematic, or even partial schematic, the 'Class D' section of the forums might be the best place to get help with choosing an inductor.
They don't fail often, so I can only presume you're building something. Good luck.
