Charge/discharge characteristics
14
The XH-HG is a capacitor with an excellent large current
discharge characteristic at least 3 V, compared to its
predecessor (XH414H).
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 of
mobile and information devices.
XH414HG/
XH414HG
XH409HG (under development)
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.
