When current flows through a conductor it becomes an inductor, when there is an inductor there is an electromagnetic field (EM). This can cause a variety of issues during PCB layout if you don’t plan ...

For RF inductor selection, José Martos and Heinz Zenkner stress the importance of evaluating inductance, natural resonant frequency, quality, DC resistance and rated current for high-frequency ...

This Design Idea shows how tocalculate the inductance of amultilayer air-core coil using only itsdimensions and resistance. If you knowthe dimensions and the number of turnson an air-core coil, you ...

Could the inductor be redesigned in a fundamentally new way? Yes, according to new work by researchers in the US, Japan and China who have made the first high-performance inductors from intercalated ...

This circuit for measurement of inductance and capacitance can be used to test whether the values of inductors and capacitors quoted by the manufacturer are correct. The principle used in the circuit ...

For decades, power-supply designers have set their inductor ripple current to somewhere between 20% and 40% of their power supply’s full rated output current. This is considered a good starting point ...

Inductors range from RF coils used in communications through switchmode inductors used in power supplies and differential and common mode inductors in EMI filters. As switchmode power supply designs ...
