WHONOES replied to the thread Tantalum capacitors Vs. Aluminium capacitors for synchronous switching converter input pin..I generally use Aluminium. -
WHONOES replied to the thread Tantalum capacitors Vs. Aluminium capacitors for synchronous switching converter input pin..Input capacitors for voltage regulators are there to decouple the device from the inductance of the wiring or pcb track supplying it and...
