In digital circuits, a 0.1uF capacitor is generally connected to the ground in parallel to the power pin of each chip (this capacitor is called a decoupling capacitor, of course, it can also be understood as a power filter capacitor, the closer the chip is, the better), because The signal in these places is mainly high-frequency signal, and it is enough to use a smaller …
Large capacitor for power outages? | Electronics Forums
For small DC appliances (such as my router) can I not just solder a large capacitor in parallel across the power and ground to keep it powered? Is there anything wrong with my idea, as long as the capacitor is above the DC voltage the router uses and has enough capacitance to power it through a very small power outage?
