PMP4466: L1 & L3 part number

Mohamed Abid

Part Number: PMP4466
Other Parts Discussed in Thread: PMP15002

We are unable to find any information about L1 in PMP4466 design, can you please share it or provide an alternate part ?

L3 in the description is 950 ohm ferrite but the PN point to 52 ohm ferrite, what is the right value ?

Thank you.

Hi Mohamed,

Sorry for the confusion. The part for L1 is a common mode choke with 1.1mH inductance, the package size is 9.5mm. The original manufacture is in China.

I found a part on a similar design (PMP15002) that is from murata - T953-0.45

Anything similar to that should work.

For the ferrite bead, the 52ohm part will work.

Thanks,

Robert

Hi Robert,

Thank you for the information.

Unfortunately, L2 in the PMP15002 is also from Dongguan Fengyue manufacturer (It seems that you miss the line, L1 is from murata and it is another inductor) .

Do you think that this one can be ok ? www.we-online.com/.../744821201.pdf
