X capacitance analysis and recommendations(I)

In contrast, the common capacitor ripple current is lower and the dynamic internal resistance is higher. Therefore, using an ordinary capacitor instead of the X capacitor, in addition to the capacitor withstand voltage can not meet the standard, the ripple current indicator is difficult to meet the requirements.

Several types of X capacitance parameters of the same type:

Model MKPX2 MKP65 Overvoltage level X2 X2 X2 Capacity 0.001 to 10uF 0.001 to 50uF 0.001 to 10uf Rated voltage 310VAC 305VAC 310VAC Withstand voltage 2000VDC 2000VDC 1333VDC Deviation ±10% ±10% ±10% Loss angle ≤0.3% ≤0.2% No standard insulation Resistance ≥ 25000MΩ ≥ 15000MΩ No standard size W*H*T 13*9*4 13*11*5 13*11*5 Certification: CQC; UL; VDE; ENEC; KC, X2 X-capacitor withstand voltage less than or equal to 2.5 kV, in line with most of the current electrical power input requirements, but there are still more requirements for parameters such as withstand voltage value and loss angle. To Nichia's MKPX2 series X2 grade X capacitors high voltage, low loss, although the loss is slightly higher than the MKP65 series X capacitors, but its high cost, so the production of high-volume products is a better choice.
