1. Zero-power Resistance of Thermistor: R

2. B-Constant

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

as (1) formula

B=Rn (R/R0) / (1/T-1/T0)............(2)

3. Thermal Dissipation Constant

When electric power P (mW) is spent in ambient

temperature T1 and thermistor temperature rises T2,

there is a formula as follows

P=C (T2-T1)..................(3)

C: Thermal dissipation constant (mW/°C)

Thermal dissipation constant is varied with dimensions,

measurement conditions, etc.

4. Thermal Time Constant

Period in which Termistor's temperature will change

63.2% of its temperature difference from ambient

temperature T0 (°C) to T1 (°C).

5. Rated Electric Power

Shows necessary electric power that Thermistor's

temperature rises 100˚C by self heating in ambient

temperature 25˚C.

6. Permissive Operating Current

It is possible to keep Thermistor's temperature rising max.

1˚C.

1. Resistance - Temperature Characteristics

POSISTORr has three main characteristics.

Although there is a negligible difference between the

normal and "Curie Point" temperature, POSISTORr

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 temperature which

the resistance value is twice the one at 25 °C.

2. Current - Voltage Characteristics (Static Characteristics)

This shows the relation between applied voltage when

voltage applied to POSISTORr causes balancing of

inner heating and outer thermal dissipation and stabilized

current. This has both a maximum point of current and

constant output power.

3. Current - Time Characteristics (Dynamic Characteristics)

This shows the relation between current and time before

inner heating and outer thermal dissipation arrive at

equilibrium state. This features having large initial current

and abruptly continuous attenuating portion.

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)

1. Be sure that the preheat-up does not melt the

soldering of this product. Excessive heat may

cause failure to open, short or insulation break

down.

2. Do not touch the body with soldering iron.

The soldering point should be min. 5mm away from

the root of lead wire.

■ 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 give a shock at handling.

Such forces may cause cracking or chipping.

2. Do not apply an excessive force to the lead.

Otherwise, it may cause junction between lead and

element to break or crack. Holding element by side

lead wire is recommended when lead wire is bent or

cut.

NTC/PTC Thermistors for Automotive

PTC Thermistor (POSISTORr) for Overcurrent Protection Lead Type

16V Series

This low-voltage, low-resistance type "POSISTOR" is

a circuit protector whose resistance value in normal

operation is very low and in abnormal situations like

motor lock or short circuit, will be increased to

restrain over current. This "POSISTOR" is most

suitable for low-voltage circuits and motor protection

for automotive grade applications.

■ Features

1. Best suited to meet the requirements for power

supply and motor protection. 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.

Durable and strong against mechanical vibration and

shock because it is a solid element.

5. Lead (Pb) is not contained in the terminations.

30-140V Series

New leaded type POSISTOR for overcurrent protection

as automotive grade can be used with wide temperature

range. This product is suitable for short-protect and

current limiting resistor on power supply equipment.

■ Features

1. This product has useful Protective threshold

current range with wide temperature range.

2. Small fluctuation in the circuit due to resistance

tolerance +/-10%.

3. Quick operating time due to small size compared

with conventional products.

4. Best suited to meet the requirements for power

supply and motor protector. Error-free operations

are assured by rush current.

5. Circuit is protected until current is turned off.

6. Restores the original low resistance value

automatically once the overload is removed.

7. Non-contact design leads to long life and no noise.

Durable and strong against mechanical vibration and

shock because it is a solid element.

8. Lead (Pb) is not contained in the terminations.

■ !Caution (Storage and Operating Condition)

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 these factors

can deteriorate the characteristics or cause product

failure 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 conditions

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 damage that may be

caused by the abnormal function or the failure of our

product.

■ Notice (Storage and Operating Condition)

To keep solderability of product from declining,

following storage condition is recommended.

1. Storage condition:

Temperature -10 to +40 degrees 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. Handling after unpacking:

After unpacking, promptly reseal this product or

store it in a sealed container with a drying agent.

4. Storage place:

Do not store this product in corrosive gas

(Sulfuric acid, Chlorine, etc.) or in direct

sunlight.

■ Notice (Soldering and Mounting)

When the lead of this product is soldered, pay

attention as follows to avoid the decline of element

characteristics or break-down of the element.

1. Use Rosin type flux or non-activated flux

2. Do not dip the body into flux (flux should be coated

to lead wire only for soldering).

3. Be sure that preheating does not melt the

soldering of this product.

■ Notice (Handling)

1. Do not apply an excessive force to the lead.

Otherwise, it may cause the junction between lead

and element to break, or may crack the element.

Therefore, holding the element side lead wire is

recommended when lead wire is bent or cut.

2. This product does not have waterproof

construction. Splashed water may cause failure

mode such as decline of characteristics or current

leak.

3. When this product is operated, temperature of some

areas may be over 100 to 160 degrees C. Be sure that

surrounding parts and inserting material can

withstand the temperature. If the surrounding part

and material are kept under such conditions, they

may deteriorate or produce harmful gas

(Chlorine gas, Hydrogen sulfide gas, Ammonia gas,

Sulfuric acid gas, Nitric oxide gas, etc.). And

such harmful gas may deteriorate the element.
