# Multiple Lead Types for 5.5V Coin Type Supercapacitors
For coin type supercapacitors, electrical specifications are only part of the selection process. The lead type must also match the PCB layout and assembly method. A correct lead type helps reduce rework and makes the product easier to install in the final device.
## Lead type options
Common lead options for 5.5V coin type supercapacitors include V type, H type, C type and T type. The suitable option depends on PCB space, mounting direction, soldering method and the original design requirement.
## Why it matters
If the lead type does not match, the component may not fit the board even when the voltage and capacitance are correct. For smart meter backup, RTC backup and PCB backup applications, this can delay sample testing and bulk production.
## Custom discussion
For project customers and OEM buyers, custom lead type discussion may be needed. Buyers can send PCB drawings, original sample photos or datasheets so that the lead type, lead pitch and size can be checked before quotation.
## LORIDA support
LORIDA supports 5.5V coin type supercapacitor selection with multiple lead type discussion, size matching, replacement model checking and sample testing before bulk order.
## Need Support?
Need to check lead type compatibility? Send your PCB drawing, sample photo or datasheet. LORIDA will help review the suitable option.
