I Description Of The MF51 NTC Thermistor
Ampfort
MF51
series
of
Glass
Encapsulated
thermistors
are
a
special
breed
of
NTC
thermistors.
Hermetically
sealed,
these
small
thermistors
eliminate
resistance
reading
errors
caused
by
moisture
penetration
and
they
function
efficiently
in
extreme
temperatures
as
well
as
under
severe
environmental
conditions.
This
class
of
thermistor
is
free
from
limitations
due
to
solder
temperature,
which
enables
them
to
offer
users
a
wide
operating
temperature
range
of
“-55
°C
to
+200
°C”.
With
diameters
of
only
1.5
mm,
the
devices’
small
size
allows
for
encapsulation
in
a
variety
of
housings,
such
as
ring
lugs
and
hex
nuts.Radial
leaded
glass
encapsulated
thermistors
provide
a
low
cost
option
for
applications
that
require
superior
stability
and
high
temperature
operation.
The
thermistors
are
glass
encapsulated
to
allow
for
operation
in
a
wide
array
of
environments
including
high
humidity
and
rapid
thermal
cycling.
The
small
size
allows
the
sensor
to
react
quickly
to
small
temperature
changes.

intake
air,
ambient,
battery,
motor
and
fuel)
,
hybrid
vehicles,
fuel
cell
vehicles,
automotive
electronics
■
Assembly
into
various
probes
of
Temperature
sensors
■
General
Instrumentation
applications
■
Temperature
measurement
and
control
commonly
used
in
HVAC
applications,
water
heaters,
microwave
ovens,
home
appliances
■
Temperature
control
in
common
household
appliances
such
as
coffee
makers,
ovens,
and
refrigerator’s.
■
Industrial
applications
may
include
monitoring
battery
pack
terminal
temperature
while
in
a
charge
state.
■
Medical
applications
that
rely
on
airflow
such
as
respirators.
■
Outdoor
applications
such
as
infrared
lighting
systems.
