A filter is a device that passes or rejects certain frequencies of a signal. Three common type of filters are the low- pass filter the bandpass filter, and the high-pass filter. An ideal low-pass ...

More and more portable devices now use ceramic capacitors for filtering of dc/dc-converter inputs. Ceramic capacitors offer the advantages of small size, low ESR (equivalent series resistance) and ...

Last month, we discussed low power factor and how resonance can disrupt facility operations. This month, we'll talk about harmonic filter design and various system parameters that affect filter ...

Although higher switching frequencies in modern dc-dc converters allow the use of lower-valued capacitors, designers continue to choose tantalum capacitors for such applications. However, the latest ...
