My dear friends, such as title, using only one capacitor filter to remove the interference of a 200 hz, the capacitance value, how to calculate?

CodePudding user response:

It depends on you what is the approximate size of the output resistance or inductance in the circuit, and then according to the formula to calculate the size of the capacitor,

CodePudding user response:

Is high or low pass, if it is low pass method choice is not the same

CodePudding user response:

Capacitance formula T=RC charge and discharge circuit, R can be regarded as a capacitance on resistance, each capacitor is impedance, f=1/T

CodePudding user response:

See you how to define on the effects of residual filter, filter out 90% or 99.9%, for example, in addition to see working current and load impedance,
General requirements can be between 470-10000, mA level 470 u play, 10 class a job 6800 uf is not enough
