Tips: Factors that Increase the ESR Value

• Bad electrical connections. The connection between the copper leads and the aluminum plates in the capacitor are usually welded or made using mechanical crimps. This type of connections introduces some series resistance, and is used because the aluminum cannot be soldered.
• The drying of capacitor electrolyte solution. As the liquid component of the electrolyte dries out due to elevated temperatures, the electrical resistance increases.
• ESR increases with increase in temperature and frequency. In power supplies with high currents, the power dissipation associated with the ESR may further increase the temperature and lead to capacitor failure.
