Current 0.4 to 1.5 A
|
These chokes are made with a toroid core in molypermalloy powder (MPP).
Compared with the iron powder (IP) storage chokes, the MPP types have smaller dimensions, lower
inductance loss and better saturation conditions.
They are mainly used in switched-mode power supplies. They can also be used as RFI suppressors.
