switch mode power supply - input filtering capacitor design



How to make input filtering capacitance circuit (capacitor bank) if values of one capacitor are not enough to handle with voltage and capacitance? For example, calculated input capacitor value for AC-to-DC converter 1.4 millifarad 640 V.


Schematic of example



Answer




They do exist if you look under Caps, Film

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
