2200uF 35V Electrolytic Capacitor

The 2200uF 35V Electrolytic Capacitor is a specialized type of capacitor that leverages an electrolyte to achieve a larger capacitance than other capacitor types. The electrolyte, a high-ion concentration liquid or gel, is a key component of this device.

🔧 Internal Structure of the Electrolytic Capacitor

The internal structure of the 2200uF 35V Electrolytic Capacitor consists of several key components:

• Anode (Positive Electrode): Constructed from aluminum, the anode is coated with an insulating layer of aluminum oxide (Al₂O₃), which serves as the dielectric.
• Dielectric: This is a thin layer of aluminum oxide with high dielectric strength.
• Cathode (Negative Electrode): This is a conductive liquid or gel, the electrolyte, which contacts an external conductive layer.
• Separator: This is 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. It typically features a safety vent on top to prevent explosion.

⚙️ Key Characteristics of the Electrolytic Capacitor

The 2200uF 35V Electrolytic Capacitor exhibits several distinctive characteristics:

• Capacitance Range: Generally ranges from 0.1 µF to 100,000 µF, offering high capacity.
• Voltage Rating: Ranges from 6.3V to 450V.
• Polarity: Electrolytic capacitors are polarized, and incorrect connection can result in leakage, heat, or explosion.
• Frequency Response: Best suited for low to medium frequencies. Not recommended for high-frequency circuits.
• Lifespan: Limited due to electrolyte evaporation, typically lasting 2,000–10,000 hours at 85–105°C.
