Philips 2200uF 10V Electrolytic Capacitor

The Philips 2200uF 10V Electrolytic Capacitor is a specialized type of capacitor that leverages an electrolyte to attain a greater capacitance than other capacitor types. The electrolyte, which can be a liquid or gel, is rich in ions.

? Internal Structure

The internal structure of this electrolytic capacitor comprises:

• Anode (Positive Electrode): Constructed from aluminum and 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 (the electrolyte), which is in contact with an external conductive layer.
• 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 equipped with a safety vent on top to prevent explosions.

⚙️ Key Characteristics

The Philips 2200uF 10V Electrolytic Capacitor exhibits the following key characteristics:

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

? Common Applications

The Philips 2200uF 10V 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
