• 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.

Capacitance
• Charge voltage
The age deterioration of the capacitor
depends on the charge voltage.
The age deterioration is accelerated
as charge voltage goes higher.

Internal Impedance
The XH414HG is a 4.8mm-diameter, 1.4mm-high
3.3V type coin-shaped capacitor. Compared to
its predecessor (the XH414H), the XH414HG
features excellent high current discharge
characteristics ranging from 3.3V to 0V.
Pb-free reflow (260°C peak temperature) is
also supported.
It is ideal for memory and RTC backup for
500μA max./3.3V, 5 hours/room temperature
High withstanding 4mm diameter capacitor
