Are the parameters of aluminum electrolytic capacitors affected by the application environment?

1 Temperature characteristics of capacitance 🍏Are the parameters of aluminum electrolytic capacitors affected by the application environment?Capacitance varies with temperature. The change itself is determined by the rated voltage and capacitor size, from 25°C to the high temperature limit, the capacitance increase is generally not more than 10%. For the lowest rated temperature of -40℃, the [...]

Power supply high frequency filter capacitor selection skills

Power supply high frequency filter capacitor selection skills 1) Theoretically, the impedance of an ideal capacitor decreases as the frequency increases (1/jwc), but due to the inductive effect of the pins at both ends of the capacitor, the capacitor should be regarded as an LC series resonant circuit, and the self-resonant frequency is The FSR parameter [...]

Which capacitor is more suitable for filter circuit?

Which capacitor is more suitable for filter circuit? Many electronic designers know the role of filter capacitors in the power supply, but the filter capacitors used at the output of the switching power supply are not the same as the filter capacitors selected in the power frequency circuit. They are commonly used as filters in the [...]
