Description
5.5V Super Capacitor – High Capacitance Button Type | 0.1F to 4.0F | H, V & C Mount Variants
The 5.5V Super Capacitor Button Series provides reliable and efficient energy storage for low-power electronic applications. These super farad capacitors are ideal for real-time clock (RTC) backup, memory retention, energy harvesting, and short-term power support.
Available in a wide capacitance range from 0.1F to 4.0F, these capacitors offer high charge/discharge efficiency and long cycle life. The button-style design makes them compact and easy to integrate into printed circuit boards (PCBs).
They come in three mounting styles — H-Type (Horizontal), V-Type (Vertical), and C-Type (Snap-in) — providing flexibility for various layout requirements.
