High-performance op amps and specialized software for PCs enable the design of wide-bandwidth active filters, but those advantages don't address the requirements of any specific application. For video ...

Here is a part of ultra-reliable, mission critical power systems that is often understated, but is nonetheless a key component to a robust design—-the surge protection filter. XP Power developed the ...

The QPI-1, an active electromagnetic-interference (EMI) filter for 48-V dc-dc converter applications, provides over 40 dB of common-mode noise attenuation and over 80 dB of differential-mode ...

A new IC-based approach to EMI filtering in ac-dc power subsystems dramatically cuts inductor size and offers other benefits as well. The nature of the EMI problem in ac-dc supplies and its ...
