Hi,

thx to my friend(thank you Honza) and his LabView skills I was able to do some crude C/W testing of the inductors. Test were rather rough - no climatic chamber/box, just a programmable power supply and constant power script in LabView. The winner is 7443340330(not on pictures), with cca 7.25C/W. The original part has C/W roughly twice as big. I have the new part soldered on one of blue boards and ready for some more testing :)

Layout is almost done, I'm going trough DRC checks and pondering about some footprint updates. Also two variants of rotary encoders are on the way - one from bourns, one from Alps.

Question for you guys (and gals.) ), do you like dents for volume control?

Take care,

Pitrsek
