47uF 100V Electrolytic Capacitor

This 47uF 100V Electrolytic Capacitor is a high-performing component that utilizes an electrolyte to achieve superior capacitance. The electrolyte, a liquid or gel rich in ions, allows this capacitor to offer larger capacitance compared to other capacitor types, making it a preferred choice for electronics engineers and hobbyists.

? Internal Structure

The internal structure of this electrolytic capacitor is meticulously designed to ensure optimal performance:

• Anode (Positive Electrode): Composed of aluminum, the anode features an insulating layer of aluminum oxide (Al₂O₃) that acts as the dielectric.
• Dielectric: A thin yet robust layer of aluminum oxide with high dielectric strength.
• Cathode (Negative Electrode): A conductive electrolyte in liquid or gel form, which contacts an external conductive layer.
• Separator: An absorbent paper layer soaked 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 explosions.

⚙️ Key Characteristics

This 47uF 100V Electrolytic Capacitor is characterized by its:

• Capacitance Range: Typically from 0.1 µF to 100,000 µF, offering high capacity.
• Voltage Rating: Ranging from 6.3V to 450V.
• Polarity: Being polarized, it's crucial to connect them correctly to avoid leakage, overheating, or explosion.
• Frequency Response: Best suited for low to medium frequencies, not ideal for high-frequency circuits.
• Lifespan: Limited due to electrolyte evaporation, typically lasting 2,000–10,000 hours at 85–105°C.
