SFAPI-270K-UL-TR规格书详情
The SFAPI Series is an entirely new line of fixed axial leaded power
inductors. When the current flowing through the coil changes, the timevarying
magnetic field induces a counter electromotive force in the
conductor which opposes the change in current that created it. As such,
inductors oppose any changes in current that pass through them. In power
supplies, an inductor’s role is to prevent sudden changes in current used.
Working alongside a capacitor, an inductor prevents sudden changes in the
power supply’s output voltage and current.
Due to the ferrite core material grade, these fixed power inductors have
high permeability, increased electrical resistivity, and low eddy current
losses such that their characteristics make them suitable for multiple highfrequency
applications. Power Inductors are used in variety of functions
including differential mode filtering, as output chokes and energy storage
devices in power supply topologies such a buck, boost, SEPIC and Cuk etc.
