Product information
V-Type layout for compact PCB backup
V-Type is a mechanical designation; electrical approval still requires leakage, ESR, temperature and backup-time verification. Usable backup duration depends on voltage drop, load current, tolerance, ESR, leakage and temperature.
Electrical profile
Define charge voltage, load current, minimum voltage, backup time and cycle frequency.
Mechanical interface
V-Type coin supercapacitor; confirm lead orientation, pitch and envelope from the controlled drawing. Verify polarity and soldering.
Application fit
Use for RTC, memory or meter-data backup only after circuit validation.
Calculate, fit and validate before approval
Define load current and hold-up time.
Set charged and minimum usable voltages.
Allow for tolerance, leakage, ESR and temperature.
Confirm footprint, leads, polarity and height.
Test voltage decay and restart in the real assembly.

Frequently asked questions
Questions to resolve before sampling
How is capacitance estimated?
Use load current, backup time and permitted voltage drop, then include tolerance, leakage, ESR, ageing and temperature.
Can C-Type, H-Type and V-Type parts be interchanged?
Not automatically. Confirm the drawing, footprint, lead orientation, polarity and profile.
Is 5.5V enough information?
No. Capacitance, leakage, ESR, temperature, charge method, load and fit also matter.
What should sample testing include?
Check charging, voltage decay, backup duration, restart, temperature, soldering and fit.
Which documents govern the order?
The selected-model datasheet, drawing, quotation and approved sample govern.
What determines MOQ and lead time?
The exact model, capacitance, leads, quantity, testing, marking and packing determine the result.
