The Extended Temperature lithium coin batteries support wider operating temperature -40 to +85 °C and
are ideal for automotive devices and outdoor IoT systems. Also CR3677X can be used as an alternative
solution to conventional cylindrical batteries.

Features
• Lightweight, High Voltage and High Energy Density
The
battery
voltage
is
3V,
that
of
normal
alkaline
or
manganese
batteries.
This
means
that
the
number
of
batteries
required
for
equipment
can
be
halved
for
maximum
space
saving
and
weight
reduction.
• Excellent Discharge Characteristics
Voltage
characteristics
remain
stable
even
for
a
long
period
of
discharge,
greatly
improving
the
reliability
of
equipment
that
uses
the
battery.
Such
equipment
is
also
maintenance-
free
(battery
replacement
is
seldom
required).
• Wide Operating Temperature Range
While
the
operating
temperature
range
of
the
Standard
is
from
-
30ºC
to
70ºC,
the
range
of
the
Extended
Temperature
has
been
expanded
from
-
40ºC
to
85ºC.
This
type
supports
electronic
components
and
IC
of
which
operating
temperature
range
is
up
to
85ºC
in
many
cases.
Also,
the
excellent
storage
characteristics
minimize
the
voltage
drop
compared
with
the
Standard
even
when
the
Extended
Temperature
is
stored
for
100
days
or
more
at
85ºC.
• Maximum capacity with coin lithium battery*1
The
capacity
"CR3677X"
*2
in
the
Extended
Temperature
has
the
largest
capacity
*1
among
coin
batteries.
This
model
has
a
nominal
capacity
higher
than
the
CR123A
battery
and
CR2
battery,
and
contributes
to
downsizing
and
slimming
of
electronic
devices.

Shipment
of
mass-
produced
CR3677X
is
scheduled
to
start
at
the
end
of
2019
• Excellent Leakage Resistance
The
newly
developed
battery
construction
and
electrolyte
ensure
maximum
leakage
resistance
over
a
long
span
of
time.
• Excellent Long-Term Reliability
Carefully
selected
active
materials
are
used
for
the
active
material
as
well
as
for
the
electrolyte.
These
materials
are
by
Murata's
innovative
technology
to
minimize
battery
self-
discharge.
The
self-
discharge
rate
at
room
temperature
and
normal
humidity
is
less
than
1%
of
the
nominal
capacity.
• UL Approved Parts
Murata's
Coin
Manganese
Dioxide
Lithium
Batteries
are
approved
by
UL.
(UL1642
File
No.
MH12566)
• RoHS Directive / European Directives
This
product
does
not
contain
Mercury(Hg),
Cadmium(Cd),
nor
Lead(Pb),
and
conforms
to
EC
regulation
values.
(Directive
2006/66/EC,
