The SMD aluminum Electrolytic capacitor is used in the pulsating circuit, and the main factor causing power consumption and heating is the ripple current (ripple voltage for capacitors with smaller capacity). Generally, the relationship curve between Failure rate and temperature is measured under the DC voltage without……

In line aluminum Electrolytic capacitor is one of Electrolytic capacitor, also called plug-in capacitance, lead capacitance. The in-line Electrolytic capacitor uses a metal foil (aluminum) as the positive electrode, and the insulating oxide layer (aluminum oxide) of the metal foil as the dielectric. The negative electr……

Use of aluminum Electrolytic capacitor 1. DC isolation: to prevent DC from passing through and allow AC to pass through. 2. Bypass (decoupling): Provides a low impedance path for certain parallel components in an AC circuit. 3. Coupling: As a connection between two circuits, it allows AC signals to pass through and tra……
