6 FAQs about [How big a capacitor should be placed before and after the magnetic beads]
How important is ferrite bead placement & input capacitor placement?
The ferrite bead placement and input capacitor placement is not as crucial. If there is not room for two capacitors to form a Pi filter, the next best thing is to delete the input capacitor. The chip side capacitor should always be there. This is very important.
Are ferrite beads a capacitor or a resistor?
For the remainder of this article, you can assume that any mention of ferrite beads refers to low-Q beads. It’s Not an Inductor, Not a Capacitor, Not a Resistor. . .
Can ferrite beads be used with bypass capacitors?
Ferrite beads used in conjunction with bypass capacitors can provide improved power-supply filtering and decoupling. Ferrite beads used in conjunction with bypass capacitors can provide improved power-supply filtering and decoupling.
Where should a capacitor be placed in a pi filter?
In practice, the capacitor on the chip side should be placed as close to the chip supply ball as possible. The ferrite bead placement and input capacitor placement is not as crucial. If there is not room for two capacitors to form a Pi filter, the next best thing is to delete the input capacitor. The chip side capacitor should always be there.
Do I need a bulk capacitor?
TI also recommends that at least one bulk (approximately 15 μF or larger) cap be present for every 10 or so power pins. This bulk capacitance recharges the smaller capacitors, but are not low enough inductance to replace them, so both bulk and closer pin decoupling capacitors are necessary.
What is the impedance of a ferrite bead?
As shown in Figure 2, the impedance of a ferrite bead is a function of frequency much like an inductor with the impedance being quite low at low frequencies, rising to a high point and then dropping off.
