Surface Mount Low Profile NTC Negative Temperature Coefficient Thermistor 44mm 45mm
Description Of The NTC Negative Temperature Coefficient Thermistor
Ampfort has released a new Thin Film NTC Thermistor. The Thin Film NTC Thermistor are frequently used for applications where space is a concern and standard design are not thin enough. With a typical thickness of 0.9mm max offers the solution engineers have been looking for. They are an ideal choice for precise temperature measurement between flat surfaces where quick time response is critical. The thermistor chip is loaded between 2 conductors then sandwiched with polyimide insulation. This provides excellent moisture resistance, along with flexibility. All the usual benefits of thermistors where sensitivity to temperature change is paramount.

Precautions Of The NTC Negative Temperature Coefficient Thermistor
•
Do
not
bend
the
resistance
coil
holder
lest
the
resistance
deviates
due
to
the
shake-off
of
chips
and
coil
holder.
•
keep
the
temperature
under
300℃
at
soldering
and
not
more
than
0.5
seconds
for
soldering.
•
Use
hot
air
gun
for
heat
shrinking
tubing
and
keep
the
air
gun
at
about
120℃
in
temperature.
•
When
soldering,
use
constant
temperature
iron,
with
one
hand
holding
the
resistor,
the
other
holding
electric
wires
for
butt-welding
to
improve
the
productivity
and
shorten
the
soldering
time.
•
Special
notice:
never
touch
the
chip
(the
top
of
resistor)
with
hand.
