What Is Low ESR - Radial Polymer Aluminum Solid Electrolytic Capacitors
WEET WPB Super Low ESR Radial Polymer Aluminum Solid Electrolytic Capacitors. Do you know what "Low ESR" means and its significance?
Introduction
"Low ESR" is the abbreviation of "Low Equivalent Series Resistance", which refers to low equivalent series resistance.
Equivalent Series Resistance (ESR) is an "equivalent" resistance characteristic exhibited by capacitors due to their internal structure (such as electrode resistance, electrolyte loss, dielectric loss, etc.) when operating at high frequencies or in alternating current.
The unit of ESR is usually milliohms (mΩ) or ohms (Ω). The smaller the value, the better the high-frequency performance of the component.
The core significance of Low ESR is as follows:
Reducing energy loss:
ESR can cause power loss during the charging and discharging process of components.
Improving high-frequency response.
Stabilizing circuit performance.
