Electrolytic Cap Structure:

Features:
- Ideal for bulk energy storage and filtering
- Clearly marked positive and negative leads for correct installation
- High capacitance in a relatively small footprint
- Commonly available from 6.3V to over 100V
- Affordable and widely used in consumer and industrial electronics
Applications:
- Power Supply Filtering – Smooths out rectified DC by filtering voltage ripples
- Energy Storage – Stores and releases energy in circuits like camera flashes or backup power
- Coupling and Decoupling – Passes AC signals between stages while blocking DC, or isolates noise
- Timing Circuits – Works with resistors in delay and timing applications (e.g., 555 timer circuits)
- Voltage Smoothing – Maintains steady voltage levels in DC circuits and regulators
