470uF 100V Electrolytic Capacitor

The 470uF 100V Electrolytic Capacitor is a specialized capacitor that utilizes an electrolyte to achieve a higher capacitance than other capacitor types. The electrolyte is a substance, either in liquid or gel form, that contains a high concentration of ions.

? Internal Structure

The internal structure of this electrolytic capacitor consists of the following components:

• Anode (Positive Electrode): Composed of aluminum, the anode's surface is coated with an insulating layer of aluminum oxide (Al₂O₃), which serves as the dielectric.
• Dielectric: A thin layer of aluminum oxide with high dielectric strength.
• Cathode (Negative Electrode): A conductive liquid or gel, which is the electrolyte, contacts a conductive layer on the outside.
• Separator: An absorbent paper layer saturated with electrolyte, positioned between the anode and cathode.
• Case: The entire structure is housed in a metal cylinder with two leads, typically featuring a safety vent on top to prevent explosion.

⚙️ Key Characteristics

The 470uF 100V Electrolytic Capacitor exhibits the following key characteristics:

• Capacitance Range: Typically ranges from 0.1 µF to 100,000 µF, providing high capacity.
• Voltage Rating: Ranges from 6.3V to 450V.
• Polarity: Electrolytic capacitors are polarized, meaning that connecting them in reverse may result in leakage, heat, or explosion.
• Frequency Response: Performs best at low to medium frequencies and is not ideal for high-frequency circuits.

? Common Applications

The 470uF 100V Electrolytic Capacitor is commonly used in:

• DC voltage filtering in power supplies
• Coupling and decoupling in audio circuits
• Delay circuits in timers
• Energy storage and voltage smoothing

It is a versatile component suitable for both Arduino and Raspberry Pi projects, as well as other electronics applications requiring voltage control and microcontroller modules.
