47 uF 16V Through Hole Electrolytic Capacitor (Pack of 40)

The description provided indicates that the component is an electrolytic capacitor with the following specifications:

• Capacitance: 47 microfarads (uF)
• Voltage Rating: 16 volts (V)
• Type: Through-hole type

As you mentioned, an insulator sits between the electrode’s relative conductors in the capacitor. This insulator is typically a thin layer of oxide formed on one of the electrodes (usually the anode) during manufacturing. This oxide layer acts as the dielectric, separating the two electrodes and allowing the capacitor to store electrical charge.

Through-hole electrolytic capacitors are commonly used in various electronic circuits where moderate capacitance values and relatively low voltage ratings are required, such as in power supply filtering, decoupling, and signal coupling applications. The through-hole design allows for easy mounting onto a circuit board by inserting its leads through holes in the board and soldering them in place.
