Solution guide “Measures Against Acoustic Noise in Power Inductors” has been released
“Measures Against Acoustic Noise in Power Inductors” has been released as a solution for silencing DC-DC converters.
 
Products such as laptop and tablet PCs, smartphones, television sets, and automotive electronic devices sometimes make high-pitched sounds when they are running. This is a phenomenon known as “acoustic noise” and is sometimes caused by passive components including capacitors and inductors. The mechanics in acoustic noise are different between capacitors and inductors, but acoustic noise in inductors is particularly complex as it involves a mix of factors. This article introduces some causes of and effective measures against acoustic noise in power inductors, which are main components in power circuits of devices such as DC-DC converters.
