Hi,
I am designing a power board based on the LM2596.
Board specifications:
1) Input - 12V
2) Outpuit 5V, 2.5A
At the output, I need to put an inductor. I examined many options and settled on two:
1. TDK - 33uH, RC 3.2A, DCR 47.4 mOhm, Isat 3.2A
2. TAITEC - 33uH, RC 6A, DCR 65 - 75mOhm, Isat 8A
What prevents to determine:
1) Is TAITEC better than TDK in terms of shielding? There will be signal lines near the inductor and I would like to minimize the influence of the inductor.
2) If TAITEC has better shielding, then in comparison with TDK it has a high DCR. 47.4mOhm vs 65mOhm. As far as I understand, the lower the DCR, the better. Is 65mOhm too high?
How to be?
