A low ESR is essential for efficient operation, especially in applications like power supplies where capacitors need to charge and discharge rapidly.
So how can you be sure you''re using the right low-ESL capacitor in your design? The guidelines I''ve compiled here should help you get started understanding how to find and select low-ESL capacitors for advanced applications. What is Low ESL?

These differences are why low ESR and low impedance capacitors are used extensively in switching power supplies to maintain the performance of the power
ESR causes power dissipation in the form of heat and affects the capacitor''s performance, especially at high frequencies. This is the resistance due to the leakage current that flows through the dielectric material of the capacitor when a voltage is applied across it.
High ESR capacitor dissipates heat in high current application and the capacitor life decrease eventually, which also contributes to the malfunction in electronics circuits. In power supplies, where high current is a concern, the low ESR capacitors are

If the ESR of the capacitor is high relative to the reactance of the capacitor ($X_C= frac{1}{2pi fC}$) at frequencies of interest, then you might want a low-er ESR capacitor. The requirement for "low-ESR" capacitors normally arises in output filters of switching power supplies, where the frequency is relatively high (kHz to MHz).
This resistance value is called "insulation resistance," and the unit is expressed as resistance [MΩ] or CR product [Ω･F], [MΩ･μF]. Behavior of insulation resistance Directly after DC voltage is applied to a capacitor, the

Capacitive Reactance (Xc): This is the opposition offered by a capacitor to the flow of AC current. It’s inversely proportional to the frequency of the AC signal and the capacitance of the capacitor. Xc = 1 / (2πfC) where: In summary, while a capacitor doesn’t have a fixed resistance, its impedance varies with the frequency of the AC signal.
Low loss capacitors dissipate less heat. Use of such components enables circuit designers to manage thermal issues in electronic circuits. In high RF applications, use of high ESR ceramic capacitors can lead to excessive heating. In low noise amplifiers, low ESR capacitors are used to increase efficiency and effective gain.
