    USB Type-C and Rapid Power

    USB has evolved from a data interface capable of supplying limited power to a primary power source with a high-speed data interface. USB Type-C™ and USB Power Delivery (PD) 2.0 (and the imminent 3.0 version) have accelerated this evolution. However, care is required to select the most cost-effective solution for the application as USB Type-C and USB PD offer multiple power levels.

    What is the function of the Y capacitor in the charger?

    When charging the charger, it will cause undue spontaneous combustion when it is charged. It will cause cell phone damage, even if it is electrocuted during charging. All this stems from the quality of electronic components in the charger. The cell phone charger y capacitor is used for common mode filtering, which is connected to L between ground or N to the ground to filter the common mode signals of L to ground or N to ground. The Y capacitance is usually used symmetrically, and the main functions are bypass; decoupling; filtering; energy storage.
