Most of the module power capacity concept is still stuck in the ideal module power capacity phase, as usual, the module power capacity is C. However, I do not know that there are many tight parameters in the power capacity of the module, and I do not know the difference between the power capacity of the 1UF ceramic module and the power capacity of the 1UF aluminum module. The actual power supply capacity of the module can be equivalent to the power supply circuit of the following modules:

C: module power capacity. Also refers to 1kW, 1V equivalent ac module power supply voltage, dc bias voltage of 0V, but there can also be many modules of the power capacity measurement environment is different. One thing to be careful about, however, is that the module's power capacity C itself varies with the environment.

ESL: the module power capacity is equivalent to the power perception of the series module. There is a sense of module power supply in the pin of module power capacity. In low frequency applications, inductance is too small to be considered. When the frequency is high, the power sense of the module needs to be considered. For example, the power capacity of a 0805 packaged 0.1uf patch module, and the power sensor of each pin module is 1.2nh, then ESL is 2.4nh. We can calculate that the resonant frequency of C and ESL is about 10MHz. When the frequency is greater than 10MHz, the module power capacity is characterized by the module power sensor.

ESR: module power capacity equivalent to series module power resistance. No matter which module power capacity value has an equivalent series module power resistance, when the module power capacity value is working at resonance frequency, the capacity of the module power capacity is proportional to the inductance, so it is equivalent to the power resistance of the module, and the power resistance of the module is ESR. Due to the different power supply capacity structure of the module, there are great differences. The power supply capacity of the aluminum module power release module ESR is hundreds to several euros, and the power supply capacity of the ceramic module is dozens of milligrams. The power supply capacity of tantalum module is between the power capacity of aluminum module and the power supply capacity of ceramic module.
