I want to know if the polarized capacitor has some advantage that they are used in some circuits?
For example, in a schematic of the BISS001 PIR controller IC, in some places, a polarized capacitor is used and in some places a non-polarized capacitor one.
Can I use a non-polarized capacitor with the same voltage and capacitance instead of these polarizing capacitors?
What I've understand from your answers is why the electrolytic capacitors are used, and why these are polarized.
But the designers of this circuit could have used a non-polarized capacitor or even polarized tantalum capacitors. Is it true? As the (Grove - PIR Motion Sensor) module uses polarized tantalum capacitors.
I want to know if the polarized capacitors are being used for circuit protection or is there any other reason (regardless of the type of capacitor.)
Is there a problem if these capacitors are replaced with non-polarized capacitors in these circuits?
