Emi mpm3612-33?

Are there any recommended components for use in EMI environments for the MPM3612-33 module?

I’m wondering if I can use this inductor?
SRP2010TMA-2R2M
2.2uH, Irms 2.3A, Isat 2.65.

Thank you!

Hi,

For the power module, you don’t need to use the inductor because it has already in the IC. You can try to follow the design of EVM3612-33-LQ-00A | 3V to 22V Input, 1A, Ultra-Low 5μA IQ, Power Module Evaluation Board | MPS.

Hi,

For this two inductor you just need to confirm that the inductor you choose can stand the input current. Your output current is only 0.1A so SRP2010TMA-2R2M is totally fine. DC resistance is related to your efficiency.
