filter
In this question Ferrite beads used to filter high frequency noise. Capacitor also can be used to reduced noise and filter out high frequency noise. Are they have the same effect on filtering high frequency noise or reducing EMI? When to use ferrite beads and when to
Why does an inductor behave as a capacitor at high frequencies?
In truth, I''ve only been told this anecdotally by an instructor, but can someone explain the physics at play? I have been told that if an inductor is driven at a high enough frequency, it will begin to behave as an capacitor, but I cannot figure out why.

3.2. Mechanism analysis of High-frequency harmonics suppression As analyzed in the previous section, the TTI-LCL consists of the equivalent inductance L gtfi on the grid-winding side, the added equivalent filter capacitor C f connected to the filter winding, and the equivalent inductance L tgfi on the traction-winding side. ...
How do smaller capacitors filter out higher frequencies than larger …
I commonly see 0.1 µF used on IC pins for decoupling. I occasionally see 0.01 µF and 0.001 µF capacitors used for filtering out higher frequencies. Is that incorrect, because I thought the impedance If practical capacitors were purely capacitive, then indeed, a larger capacitor would do an even better (or at least "as good") job of filtering …

Calculation and modelling of transformer parasitic capacitance
Parasitic capacitance is an important parasitic parameter of high-frequency transformer. It is the common-mode coupling channel between the primary and secondary sides of the transformer. This paper analyzes several types of typical transformer parasitic capacitance models and introduces the most suitable one for …
High-pass Filters
A high-pass filter allows for easy passage of high-frequency signals from source to load, and difficult passage of low-frequency signals. Capacitive high-pass filters insert a capacitor in series with the load; inductive high-pass filters insert a …
