Hi All,

I'm not sure what an inductor is, and what it does.  I copied part of a schematic (http://www.sparkfun.com/datasheets/Prototyping/LiPower-v11.pdf) to go into a development board that I have.  The part number of the inductor is CDRH3D28, and I can't find the component on Digikey.  The value that I'm suppose to find is 4.7uH, 1.2A.  The products that I find are 4.7uH, 1.68A, and 10uH, 1.18A.  Any help on which part I should get (or a different part on Mouser)?

Thanks,
Qtechknow

Thanks.  Do you know which part that I should get from Mouser/Digikey?

Page 16 of the TPS61200 data sheet discusses the inductor, in terms of uH needed and current carrying capability.

Digikey carries Wurth Electronics inductors, here's an example.

Thanks.  Do you know if they carry CDRH3D28 packages of them???
