Models simulate high-frequency inductances
Würth Elektronik eiSos and Modelithics proudly present the results of their cooperation project: with immediate effect, Microwave Global Models™ products are now available for three product families of SMT high-frequency inductors. HF developers now have the opportunity to test the 0402 and 0603 designs of the WE-MK, WE-KI, and WE-TCI coil families in simulations. The […]
Choosing inductors for energy efficient power applications
Energy efficiency in power supplies can be as much about the inductors as about the circuit topology. A few simple calculations can prevent unpleasant surprises. CHRIS HARE, LEONARD CRANE COILCRAFT, INC. In high frequency dc-dc converters, inductors filter out the ac ripple current superimposed on the dc output. Whether the converter steps the voltage down […]
