Ferrite bead inrush current rating

[ku637]

Hi,

I'm analyzing a design of a board using a ferrite bead BLM18PG471SN1D it is 2A rated and used in a supply input operating at 15V, maximum steady state operating current is <1.4A.

The board has got an inrush current that can go upto 28A for <2ms.
I would like to know how if it is safe to use this part as im concerned about reliability.

How to make understand if this inrush spec is within the capacity of the ferrite bead.?


Thanks for any help,

Regards

Well, first of all that part is rated for 1Amp max, not 2.
