Presumably the cheaper manufacturers had missed something or cut some corners while reproducing (or ripping off) the Japanese research. The type of capacitor affected was cheap, large capacitance, low ESR capacitors. These are the kind of thing that appears in huge numbers of consumer devices, so the problem became known in the wider community.

Before I have explained the formula for calculating and optimizing resistor and capacitor values in a transformerless power supply, it would be important to first summarize a standard transformerless power supply design. Referring to the diagram, the various components involved are assigned with the following. . We all know how Ohm’s law works and how to use it for finding the unknown parameter when the other two are known. However, with a capacitive type of power supply having peculiar. . Typically, a transformerless power supplywill produce an output with very low current values but with voltages equal to the applied AC mains (until it’s loaded). For example, a 1 µF, 400 V (breakdown voltage) when connected. . In the entire transformerless design discussed above, C1 is the one crucial component which must be dimensioned correctly so that the current output from it is optimized optimally as per the load specification. Selecting a. . Resistor for the Load: When an LED is used as the load, it is recommended to choose a capacitor whose reactance value allows only the maximum. [pdf]

In , a capacitor is a device that stores by accumulating on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the . It is a with two . Capacitor voltage is crucial in electrical circuits. It's the potential difference across a capacitor's plates. During charging, voltage builds as charge accumulates. [pdf]
The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads. Note that capacitance C is ALWAYS positive and never negative. The greater the applied voltage the greater will be the charge stored on the plates of the capacitor.
When an electric potential difference (a voltage) is applied across the terminals of a capacitor, for example when a capacitor is connected across a battery, an electric field develops across the dielectric, causing a net positive charge to collect on one plate and net negative charge to collect on the other plate.
Also, because capacitors store the energy of the electrons in the form of an electrical charge on the plates the larger the plates and/or smaller their separation the greater will be the charge that the capacitor holds for any given voltage across its plates. In other words, larger plates, smaller distance, more capacitance.
A capacitor can be charged by connecting the plates to the terminals of a battery, which are maintained at a potential difference ∆ V called the terminal voltage. Figure 5.3.1 Charging a capacitor. The connection results in sharing the charges between the terminals and the plates.
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
A potential difference | ∆ V | is then applied across both capacitors. The left plate of capacitor 1 is connected to the positive terminal of the battery and becomes positively charged with a charge +Q, while the right plate of capacitor 2 is connected to the negative terminal and becomes negatively charged with charge –Q as electrons flow in.
