A supercapacitor or double layer capacitor is a brand-new type of energy storage device. It is one of the most advanced inventions in recent years, which is much better than conventional capacitors in many aspects. Supercapacitor or ultracap is now widely used, of which the coin cell supercapacitor plays an important role in the application of supercap capacitor. Kamcap is one of the most professional supercapacitor suppliers from China. Kamcap strictly controls the production lines of small supercapacitors, and our coin capacitor meets the ISO 9001 Standard and ISO 14001 Standard.
A 1 Farad capacitor, especially a 1F supercapacitor, is a powerhouse in a tiny package. Unlike small-valued traditional capacitors, a 1F capacitor can store a significant amount of energy for its size, enabling short-term power backup and peak power delivery in countless modern electronics.
At Kamcap, we specialize in high-performance coin-type supercapacitors, including our popular 5.5V 1 Farad capacitor models. These devices are engineered for applications where reliability and space-saving design are critical.
Common Uses for a 1 Farad Capacitor:
Memory Backup: Acts as a miniature battery to prevent data loss in devices like RAM, smart meters, and real-time clocks during a main power interruption or battery replacement.
Power Bridge: Provides a critical few seconds of power to allow for an orderly shutdown in car dash cams, smart home devices, and digital cameras, preventing file corruption.
Peak Power Assistance: Delivers instant bursts of energy to support power-hungry components in motor drives, small toys, and LED flashes, easing the load on the primary battery.

Using a 5.5V rated supercapacitor in a 5V circuit provides a critical voltage safety margin. Standard 5V power rails can sometimes experience minor voltage spikes or fluctuations. The 5.5V rating ensures the capacitor operates well within its limits, significantly reducing the risk of electrolyte degradation and extending the overall MTBF (Mean Time Between Failures) of your device.
The choice depends entirely on your PCB layout and space constraints:
Type V (Vertical): Best for high-density boards where footprint area is limited but height is available.
Type H (Horizontal/Low-profile): Ideal for slim electronic devices like handheld terminals or smart meters where vertical clearance is restricted.
Type C (Stacked/Button): Often used for standard through-hole mounting or as a direct replacement for backup batteries in legacy systems.
Yes, in many applications. Unlike batteries, a 1.0F 5.5V supercapacitor offers over 1 million charge-discharge cycles and requires zero maintenance. It is perfect for providing "last gasp" power for data transmission or maintaining Real-Time Clock (RTC) functions during power outages, provided the backup duration needed is minutes to days rather than months.
Supercapacitors are much simpler to charge than batteries. They generally only require a current-limiting resistor to prevent the initial inrush current from overloading the power supply. They do not suffer from the "memory effect" and can be charged and discharged at the same voltage level.
At room temperature (25°C), our 5.5V series is designed to last for the entire lifespan of the host device (often 10+ years). Even at its maximum rated temperature of 70°C, it maintains an endurance life of 1,000 hours, making it a highly reliable component for industrial-grade electronics.
