Induktorer til højtydende switching regulatorer
Würth Elektronik introducerer koblet flatwire induktor tll brug sammen med højtydende switching regulatorer (in english).
High-performance switching regulators require powerful inductors with stable inductance and soft saturation to cope with high currents. Würth Elektronik eiSos has developed the WE-CFWI range of coupled flatwire inductors.The windings can be connected in series and parallel. This means that this compact double choke can be used in SEPIC, CUK or Buck/Boost converters. The special core material enables high saturation currents of up to 62 A, which is four times higher than with previously comparable double chokes.
Soft saturation, a very tight tolerance inductance and very low DC resistance with only 10 % tolerance are convincing. The leakage inductance of less than 0.5 % reduces peaks in start-up currents. Excellent inductance stability over temperature and low DC resistance makes this component particularly suitable for high-performance switching regulators.
This component is available in an extended temperature range up to 150 °C with inductance values of up to 17.6 µH.
