PTC
THERMISTOR
FOR
OVERCURRENT
LIMITER
Description
This
case
type
Posi-R
is
ideally
suited
for
motor
starting
in
air-conditioners.
Linear
PTC
Thermistor
(LPTC)
resistance
increases
with
the
temperature
rises
in
linearity,
displays
a
virtually
linear
positive
temperature
coefficient
over
their
entire
temperature
range,
suitable
in
measurement
and
control
system,
temperature
compensation.
As
the
construction
material
is
mainly
semiconductor
monocrystalline
silicon,
also
called
silicon
temperature
sensor,
silicon
thermistor,
sometimes
referred
to
as
silistors.
As
the
temperature
coefficient
is
positive,
the
silicon
temperature
sensors
exhibit
fail-safe
operation
when
a
system
overheats.
Furthermore
silicon
is
inherently
stable,
so
silicon
temperature
sensor
are
extremely
reliable
and
have
very
long
operational
lifetimes.
Hermetically
sealed
glass
package,
axial
leaded,
2
leads,
can
operate
in
high
temperature
and
moisture
environment.
Linear
PTC
thermistor
in
small
dimension,
tightness,
convenient
for
automatic
installation.

2.1 |
Zero Power Resistance and allowable deviation
|
3.3KΩ±30% |
After being placed in the air at 25 ℃± 2 ℃ for 2 hours, measure with a voltage not exceeding 1.5vdc. Figure 2 |
|
2.2 |
Switching temperature (Curie temperature) |
T25=75±7℃ |
The temperature corresponding to the resistance temperature characteristic (curve) 2 times R25 resistance value is specified as the switch temperature. |
|
2.3 |
rated operational voltage |
220VAC |
The withstand voltage of the element allowing long-term normal operation. |
| 2.4 | maximum operating current (Imax) | 60mA | The maximum initial current that can flow on PTC is specified as the maximum current. |
|
2.5 |
withstand voltage
|
600VAC/60S ΔR/Rn≤∣±20% ∣ |
Starting current: 0.06a, starting Voltage 220VAC, lasting for 10s; Then it is converted to high voltage (600vac) for 60s. After recovering for 4-5 hours under normal temperature and pressure, the rated zero power resistance value is retested. |
