0.22F 5.5V Electrolytic Super Capacitor
Reliable 0.22F 5.5 Volt Super Capacitor for Backup Power
Looking for an easy solution to keep your electronics running smoothly during power interruptions? This 0.22F 5.5V super capacitor offers dependable backup power for devices like digital clocks, memory circuits, toys, and microcontrollers. It’s often used for memory backup, real-time clock (RTC) modules, and other applications where extended, rechargeable power is needed.
Key Features of the 0.22F Super Capacitor
- Capacitance: 0.22 Farad (220,000uF)
- Voltage Rating: 5.5 Volts DC
- Type: Electrolytic “coin cell” super capacitor
- Lead Spacing: Standard radial leads for easy PCB mounting
- Compact Design: Fits into small spaces, ideal for DIY projects
- Rechargeable: Can be charged and discharged many times
How to Use Your 5.5V Super Capacitor
Simply connect the capacitor in parallel with the circuit needing backup power. During normal operation, the super capacitor charges up. When primary power is disconnected, the capacitor provides stable voltage to keep memory or RTCs running without interruption.
Note: Ensure that the voltage across the capacitor does not exceed 5.5V to prevent damage.
Applications for This Electrolytic Super Capacitor
- Memory backup for microcontrollers and SRAM
- Real-time clock battery replacement
- DIY electronic projects and toys
- Small backup power supplies
- Maintaining settings in electronics during power loss
