Esr in ceramic capacitors.
Esr ceramic vs electrolytic.
But low esr is not always the primary consideration and in a development outside of electrolytic devices murata has actually increased esr of some of its multilayer ceramic chip capacitors in order to control unwanted resonances that can reduce the decoupling performance at peak frequencies.
How esr affects the performance of capacitor.

Generally speaking while electrolytic capacitors provide the largest capacitance they suffer significant degradation in capacitance and leakage current at higher temperatures and frequencies.
Aluminum electrolytic and tantalum capacitors have high esr compared with the box type or ceramic capacitors.
Ceramic capacitors have a very low esr and esl that makes them suitable for transient performance but they have limitations on capacitance.
If the esr is too high then the current flow through the circuit would be too small.
For electrolytic capacitors the equivalent series resistance esr is an important concept.
However electrolytic capacitors have stable capacitance with high bias voltage and are inexpensive.
The figure below shows how the esr impedance of a capacitor changes with resistance.
Electrolytic capacitors are famous for having higher volumetric efficiency.
This means a small capacitor is able to hold larger amount of charges than a ceramic capacitor of the same size.
Ceramic capacitors have very low esr but capacitance.

Equivalent series resistance is one of the most important parameters to consider when selecting a ceramic capacitor for your electronic circuit.
Ceramic capacitor has two metal sheets at the terminals to store charges.
100µf aluminum electrolytic capacitor.
Multiple ceramic layers may also be arranged and compressed together to form a block reducing equivalent series inductance and creating a monolithic ceramic capacitor.
Esr value of the capacitor is a crucial factor for capacitor output.
However modern advancement in capacitor manufacturing technology makes it possible to manufacture super low esr capacitors.
