PTC THERMISTOR
FOR CIRCUIT PROTECTION
PTH8L Series
Posistor
®
protects circuit components at the load and power
supply sides by reducing the current when abnormal current
flows through the circuit.
I
Posistor
®
continues to protect a circuit until the abnormal
current situation is corrected.
I
Posistor
®
returns to the initial condition when the overcurrent
is removed.
I
No noise is emitted due to no contact.
I
Excellent durability
I
Posistor
®
is resistant to mechanical vibrations and shocks
due to solid element construction.
I
Non-contract design protects circuits quickly

.
TERMS
INITIAL RESISTANCE (R@25°C)
The resistance of the posistor is the measured value with a
terminal voltage of less than 1VDC to prevent self-heating.
MAXIMUM RATED VOLTAGE
The maximum voltage that can be applied to the posistor
continuously in the operating temperature range.
MAXIMUM RATED CURRENT
The maximum in-rush current that may be repeatedly
introduced into Posistor
®
when the circuits operates
abnormally.
NON-TRIP CURRENT
At maximum operating temperature, this is the maximum
current value that doesn’t trip the Posistor
®
to the high
resistance state. Under these conditions, Posistor
®
performs
as a fixed resistor.
TRIP CURRENT
The minimum current value that will cause the Posistor
®
to
trip to the protective high resistance state.
OPERATING TEMPERATURE RANGE
The ambient temperature range in which a Posistor
®
can
be used when the maximum voltage is applied. Range is
–10°C to +60°C.
TEMPERATURE CHARACTERISTICS
(CURIE POINT)
The temperature at which the resistance of the Posistor
®
is
twice the initial 25°C resistance value.
