Hi,
I am using the TPS23756 device to create POE products.
I have selected the parts based on the information of EVM(SLVU329A).
However, there are some parts that are not already supplied, so we are considering alternative parts.
Among them, C15(22uF/EEVFK1E220R) used in the EVM circuit also needs to consider alternative parts.
I am considering EEFCX1E220 R as an alternative product of C15.
Although this product is an aluminum electrolytic capacitor, it has lower internal impedance than the previous part.
I want to ask you a question.
Is it possible to use EEFCX1E220R instead of EEVFK1E220R?
Also, the internal resistance is further lowered, but is it possible to use a ceramic capacitor?
Does the difference in internal impedance affect the magnitude of noise?
Best Regards,
