Charge/discharge characteristics
6
The XH series capacitor has a better discharge characteristic
above 3V. It is an environmentally friendly product that
is reflow mounted by Pb-free soldering. It features high
capacity, and long-term reliability, as well as a wide operating
voltage range. It is thus suitable for backup power supply
of clock and memory functions on mobile and information
devices.

A ripple (high frequency fluctuation of
voltage) in the charge voltage extremely
lowers the capacitor performance.
Be sure to charge capacitors with a
stable voltage.
