Description
Embedded Capacitor 16V 18000uF—Overview
The horn electrolytic capacitor is a capacitor, also known as an aluminum electrolytic capacitor. It consists of two electrodes (aluminum foil) and an electrolyte (aluminum oxide). The electrodes are separated by an electrolyte to form a capacitor. It is characterized by high capacitance density, low ESR (equivalent series resistance), low temperature drift, and long life. Embedded Capacitor 16V 18000uF is commonly used in electronic devices, such as power supply circuits, audio amplifiers, radio frequency circuits, etc.
