Unexpected EMI does not always require a
complete PCB redesign. This episode explains how the EMI Patch
combines a conductive metal layer with a magnetic absorber to
reduce interference in near field and far field conditions, with
advice on placement, grounding, isolation, and applications based
on real examples.

When a DC/DC output stage needs bulk
capacitance, aluminum electrolytic capacitors are often the default
choice. But what happens when ripple current pushes you into
paralleling multiple capacitors, lifetime calculations come up
short, or ESR becomes the design problem instead of the design
solution? While electrolytic...

In this episode, we break down what Power
Factor Correction (PFC) is actually doing inside an offline power
supply. We will explain why bridge-rectifier front ends create
distorted input current, how active boost PFC reshapes that
waveform, and what engineers need to know about conduction modes,
interleaving, EMI...
