POSISTORr for Circuit Protection
for Overcurrent Protection 6V Series
D max.
T max.
Smaller size and lower resistance by new raw material
having low resistivity. Smaller size can provide
faster operating time. Smaller voltage drop when
voltage is applied to this PTC and excellent heat
resistance due to ceramic construction. Initial
resistance will not be changed by soldering heat or
self heating during overcurrent protection. In
addition, resistance of "POSISTOR" during operation is
large and it will return to initial low value when
abnormality to removed.

Features
1. Best suited to meet the requirements for power
supply circuits. Error-free operation is assured
by rush current.
2. Circuit is protected until current is turned off.
3. Restores the original low resistance value
automatically once the overload is removed.
4. Non-contact design leads to long life and no noise.
s
Applications
1. Overcurrent protection (countermeasure for short
circuit) of USB power supply circuit in Personal
Computers and peripherals.
2. Overcurrent protection of low voltage circuit
(countermeasure for short circuit test of safety
standard).

PTGL Series Specifications and Test Methods
Item
Continuous Operating
Temperature
Rating value
-10 degree to +60 degree
Method of examination
The temperature range with maximum voltage applied to the
POSISTORr.
Resistance value is measured by applying voltage under
1.5Vdc (by a direct current of less than 10mA) at 25°C.
(But it must be measured after maximum voltage is applied for
180 seconds and then is left for 2 hours at 25°C.)
As for 6V and 16V series, measurement probe should be con-
nected on the lead wire at the point within 2mm from the below
side of the forming. Resistance should be measured 4 wing
method.
We apply AC voltage 120% (110% for 6V series) that of the
maximum voltage to POSISTORr by raising voltage gradually
for 180±5 seconds at 25°C. (A protective resistor is to be
conected in series, and the inrush current through POSISTORr
must be limited below max. rated value.)
The load is gradually applied to each terminal of POSISTORr
until the force of the following table in the axial direction with
fixing POSISTORr's body itself and this load is being kept for
10 seconds.

POSISTORr is held so that it is perpendiculer to the lead wire
with the following lead hanging in the axial direction of the lead
wire. The lead wire is slowly bent toward 90° and returned.
Then it is slowly bent in the opposite direction and returned to
original state.

Solderability
Solder is applied around the lead wire covering 3/4 or more of
the circumference without gap in the axial direction.
The Lead wire of POSISTORr is soaked in a Isopropyl
alchohol (JIS K 8839) solution (about 25wt%) of colophony (JIS
K 5902) for 5 to 10 sec. And, each lead wire is soaked in
Molten solder (JIS Z 3282 H60A) at 235±5°C from the bottom
to a point of 2.0 to 2.5mm for 2±0.5 sec.
The lead wire of POSISTORr is soaked in Molten solder (JIS Z
3282 H60A) at 350±10°C from the bottom to a point of 2.0 to
2.5mm for 3.5±0.5 sec. And, after the device is being left at
room temperature (25°C) for 24±4 hours, the resistance is
measured.
POSISTORr is set in an environmental chamber at 40±2°C
and 90 to 95% humidity for 500±4 hours. And after the device
is being left at room temperature (25°C) for one hour, the resis-
tance measurement is performed.
POSISTORr is set in an environmental chamber at 60±3°C
with maximum voltage applied for 1.5 hours and then is left
without voltage applied for 0.5 hours. This cycle is repeatedfor
1000±10 hours, and after the device is left at room temperature
(25°C) for one hour, the resistance measurement is performed.
(A protective resistor is to be connected in sereis and the
inrush current through POSISTORr must be limited below
max. rated value.)
