XH Capacitor
Pb-free reflowable
XH311HG/XH311HU/XH414HG
FEATURES
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.
• Pb-free reflowable:
Superior heat resistance (260°C peak) allows reflow
soldering by Pb-free solder
• Wide operating voltage range from 0V to 3.3V
• High capacity: 0.08F with “414” size
• Long Cycle Life:
At least 10,000 times of charge/discharge
• Simple charging circuit (constant voltage charging)
• Wide operating temperature range:
Operating temperature range: −20°C to +60°C
For using the battery at a temperature out of the above
temperature range, please consult us.
• RoHS Compliant
APPLICATIONS
Backup power supply for memory and clock functions of
smartphone, tablet, cellphone, PHS, cordless phone, digital
still camera, game machine, and printer, etc.

<APPLICATION NOTES>
• Prohibition ripple charging
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.
• Charge voltage
The age deterioration of the capacitor
depends on the charge voltage.
The age deterioration is accelerated as
charge voltage goes higher.
• Usage environment
Aging degradation of the capacitor varies
depending on the usage environment
(temperature and humidity).
