    Post 47uH inductors on sproggy mk2.5

    I'm building sproggy's mk2.5 but the 47uH inductors that I found at digikey are much smaller in size than the one's in sproggy's picture. Will they still work? The digikey part # for them is M6015-ND at digikey.com

    Well, they might not be high enough current, they are supposed to be rated at like 7.5amps or something, and I don't think that smaller ones would be rated as highly..

    I looked up the specifications at farnell and the inductors seems to be 47uH at 8.5A. I found them at fastpower.com but the lead time is 8 weeks and shipping is $25, for two parts!

    Would a 47uH coil from jw miller (through digikey) rated at 9 amps work?

    Yeah, should do, but you will probably have to bend the legs around to get it to fit. I had to aswell with parts from Gowanda...

    Ummm....
    *cough*F*cough*R*cough*E*cough*E*cough* *cough*S*cough*A*cough*M*cough*P*cough*L*cough*E*c ough*

    The part number that I got was......
    DB3-472
    But when using this part, you will have to mount some of the components on the bottom of the PCB because the inductors cover the holes...

    What 10uH inductor are you using, the 2 different types I have (from gowanda) are not suitable...

    Well I asked for a free sample from Wilco and will do the same for gowanda. Actually, I found the exact inductors at Sager Electronics but they require a $25 minimum order and I do not want to buy 11 coils. Do you or does anyone else want to do a group buy? I ordered two inductors from coilcraft for the 10uH, part number PCV-0-103-05.
