# 0.1F to 4F Coin Type Supercapacitor Series for Electronic Devices
Different electronic devices require different backup times, PCB space and lead types. This is why a complete 5.5V coin type supercapacitor series is useful for distributors, traders and OEM buyers who need more than one model for their customers or projects.
## Model range
The LORIDA 5.5V coin type supercapacitor range includes 0.1F, 0.22F, 0.33F, 0.47F, 0.68F, 1F, 1.5F and 4F options. 0.1F is often used for small RTC backup. 0.22F and 0.33F can be used for meter and PCB backup. 0.47F is a popular model for smart meter and RTC applications. 1F and 1.5F are suitable when higher capacitance is needed. 4F can support longer backup requirements.
## Application matching
Applications include smart meter backup, water meter backup, gas meter memory backup, RTC circuit backup, PCB backup, industrial control boards and small electronic devices. Choosing the right capacitance depends on backup time, load current and available board space.
## Lead type support
Different PCB layouts may require V type, H type, C type or T type lead options. Buyers should confirm lead type, lead pitch and installation direction before placing an order.
## Buying suggestion
For buyers who are not sure which value to select, it is better to send the application and target backup time first. LORIDA can help narrow the selection and suggest sample testing before bulk order.
