Storage Chokes

Application

Storage chokes, wound on powdered MPP core, specially qualify for use

as storage of energy in switched power supplies (switching mode

regulators). Switched power supplies allow small size with high efficiency

and stabilized output voltage. Most important features of this line of

chokes are the following:

•reduced magnetic reversal

•small size

•constant inductance at high alternating field modulation and large

DC magnetization.
