Quick Details
Specifications
Toroid cores for switching power supply made of nanocrystalline are featured by its high magnetic
permeability and low loss. It's the ideal material for many components in single-ended, push-pull or bridge type high frequency switching power supply, such as main transformer, magnetic amplifier, choking coil, stored inductance, filtering inductance, common mode choke and spike blocker.
Application :
power supply modules.
▲ Applicable in different kinds of work mode, like single-ended, bridge type, push-pull, etc.
Properties :
▲ High magnetic permeability and low coercivity
▲ Low loss, low temperature rise
▲ A flexible selection of cores with different magnetic performances according to the work mode of
switching power supply.
Magnetic properties
▲ Properties compared to ferrite core
