Basic Characteristics
1. Zero-power Resistance of Thermistor: R
Resistance vs. Temperature

Resistance vs. Temperature Characteristics, R/R25
Measured by zero-power in specified ambient
temperatures.
R=R0 expB (1/T-1/T0) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . (1)
R: Resistance in ambient temperature T (K)
(K: absolute temperature)
R0: Resistance in ambient temperature T0 (K)
B: B-constant of Thermistor
2. B-Constant
as (1) formula
B= n (R/R0) / (1/T-1/T0)
3. Thermal Dissipation Constant
When electric power P (mW) is spent in ambient
temperature T1 and thermistor temperature rises T2, the
formula is as follows;
P=C (T2-T1)
C: Thermal dissipation constant (mW/°C)
Thermal dissipation constant varies with dimensions,
measurement conditions, etc.
4. Thermal Time Constant
Period in which Thermistor's temperature will change
63.2% of its temperature difference from ambient
temperature T0 (°C) to T1 (°C).

of POSISTOR
POSISTOR
Basic Characteristics
Although there is a negligible difference between the
normal and "Curie Point" temperature, POSISTOR
shows almost constant resistance-temperature
characteristics. Yet they have resistance-temperature
characteristics that cause resistance to sharply increase
when the temperature exceeds the Curie Point.
The Curie Point (C.P.) is defined as the temperature at
which the resistance value is twice the one at 25 °C.

Ceramic Substrate
· NTC Thermistor should be mounted on the Ceramic substrate with "Standard Land Dimensions" by our recommendable conductive glue (PC3000:
Manufactured by Heraeus) and be tested. Thickness of the conductive glue screening should be 50μm.
· R25 means the zero-power resistance at 25°C.
· B25-50 is calculated by the zero-power resistances of NTC Thermistor at 25°C and at 50°C.
· After each test, NTC Thermistor should be kept for 1hr. at room temperature (normal humidity and normal atmospheric pressure).
Then the resistances (R25 and R50) should be measured and the appearance should be visually examined.
· In the case that of R25 or B25-50 changes are greater than the specified value due to the method of mounting with conductive glue, these specifications
should be judged by an evaluation with the chip only (not mounting).

NTC Thermistors Thermo String Type !Caution/Notice
!Caution (Storage and Operating Conditions)
This product is designed for application in an
ordinary environment (normal room temperature,
humidity and atmospheric pressure).
Do not use under the following conditions because
all of these factors can deteriorate the product
characteristics or cause failures and burn-out.
1. Corrosive gas or deoxidizing gas
(Chlorine gas, Hydrogen sulfide gas, Ammonia gas,
Sulfuric acid gas, Nitric oxide gas, etc.)
2. Volatile or flammable gas
3. Dusty conditions
4. Under vacuum, or under high or low pressure
5. Wet or humid locations
6. Places with salt water, oils, chemical liquids or
organic solvents
7. Strong vibrations
8. Other places where similar hazardous conditions
exist
!Caution (Other)
Be sure to provide an appropriate fail-safe function
on your product to prevent secondary damages that may be
caused by the abnormal function or the failure of our
product.
4
Notice (Storage and Operating Conditions)
To keep solderability of product from declining, the
following storage conditions are recommended.
1. Storage condition:
Temperature -10 to +40°C
Humidity less than 75%RH (not dewing condition)
2. Storage term:
Use this product within 6 months after delivery by
first-in and first-out stocking system.
3. Storage place:
Do not store this product in corrosive gas
(Sulfuric acid gas, Chlorine gas, etc.) or in direct
sunlight.
Notice (Rating)
Use this product within the specified temperature
range.
Higher temperature may cause deterioration of the
characteristics or the material quality of this
product.
Notice (Soldering and Mounting)
Please note as shown below when you mount this product.
1. Do not melt solder in the resin head when you solder
this product. If you do so, it has a possibility of wire break,
electric short mode failure and wire coating break.
In case you cut the lead wire of this product less than
20mm from the resin head, the heat of the melted solder
at the lead wire edge is propagated easily to the resin
head along the lead wire.
2. Do not touch the resin head directly with the soldering iron.
It may cause the melting of solder in the resin head.
3. Do not separate the parallel lead wires 10mm or less
from the resin head, when you separate parallel lead
wires.
4. If you mold this product by resin, please evaluate
the quality of this product before you use it.
5. Do not bend the lead wire radius 1mm or less when
you bend the lead wire.
Notice (Handling)
The ceramic of this product is fragile, and care must
be taken not to load an excessive press-force or
to give a shock at handling.
Such forces may cause cracking or chipping.

Do not store this product in corrosive gas
(Sulfuric acid gas, Chlorine gas, etc.) or in direct
sunlight.
Notice (Rating)
Use this product within the specified temperature
range.
Higher temperature may cause deterioration of the
characteristics or the material quality of this
product.
Notice (Soldering and Mounting)
Please note as shown below when you mount this product.
1. Do not melt the solder in the resin head, when you solder
this product. If you melt the solder in resin the head,
the wire could break and short.
If you cut the lead wire of this product less than 8mm
from the resin head, the heat of the melted solder at the
lead wire edge is propagated easily to the resin head
along the lead wire. Please do not cut this product below
9mm.
2. Do not touch the resin head directly with the solder iron.
It may cause the melting of solder in the resin head.
3. If you mold this product with resin, please evaluate
the quality of this product before you use it.

NTC Thermistors Temperature Sensor Lead/Lead Insulation Type !Caution/Notice
Continued from the preceding page.
Notice (Soldering and Mounting) Insulation Type
Please note as shown below when you mount this product.
1. Do not melt the solder in the resin head when you solder
this product. (more than 25mm in full length of the
product).
If you melt the solder in the resin head, it has posibility
that the wire could break and short.
2. Do not touch the resin head directly with the solder iron.
It may cause the melting of solder in the resin head.
3. When additonal processing is carried out on this product
(such as bonding, resin molding, and resin coating, etc.),
please perform an audit of quality level on an automated
machine and only use the product after confirming its
reliability.
Please talk to us if you have concern matter, like
process it under the high temperature and the high
pressure.
(For example, exposed to high-temperature and
high-pressure environment as mold sealing with
injection molding.)
Notice (Handling)
1. The ceramic element of this product is fragile, and
care must be taken not to load an excessive
press-force or not to cause a shock at handling.
Such forces may cause cracking or chipping.
2. Do not apply excessive force to the lead.
Otherwise, it may cause the junction between lead and
element to break or crack. Holding the element by the
side lead wire is recommended when lead wire is bent
or cut.
Notice (Handling) Insulation Type
1. The ceramic element of this product is fragile, and
care must be taken not to load an excessive
press-force or not to cause a shock at handling.
Such forces may cause cracking or chipping.
Especially under high-temperature environment,
there is a possibility that epoxy resin will become soft.
When you set up the processing environment, please
examine the processing method after evaluating the
quality of this product.
34
2. Do not apply excessive force to the lead.
Otherwise, it may cause the junction between lead and
element to break or crack.
Holding the element by the side lead wire is recommended
when lead wire is bent or cut.
Handle the lead with care; there is a possibility
that a crack may go into the polyurethane
insulated coat when bending the lead.

1. Rapid operation to protect the circuit in an
overcurrent condition abnormality such as a
short circuit.
By removing the overcurrent condition, these
products automatically return to the initial
condition and can be used repeatedly.
2. Suitable for countermeasure to short circuit test
in safety standard.
3. Stable resistance after operation due to ceramic
PTC.
4. Similar size (0603 size) is possible due to the
large capacity for electric power.
5. Possible to use these products as current
limiting resistors with overcurrent protection
functions
6. The SMD type's small size and light weight are
helpful in miniaturizing the circuit.
