REMINDERS FOR USING THESE PRODUCTS
Before using these products, be sure to request the delivery specifications.
SAFETY REMINDERS
Please pay sufficient attention to the warnings for safe designing when using this products.
Incorrect usage may lead to destroyed NTC thermistors and damages or malfunctions with the devices used.
Please use them within the ranges of the ratings and performance provided in the catalog and delivery specifications upon confirming
the environments where they are to be used and installed.
Do not use them outside the operating temperature range.
Do not use them with the ratings or maximum permissible power levels exceeded.
Do not quickly apply 5mW or more of load with the constant-voltage power supply in the NTC thermistors as this may lead to staying in
thermal runaway mode or the red-shorting of chips.
Please be cautious of the applied voltage in thermistors as instruments may malfunction with the lowering of resistance due to self
heating.
With instruments that consumers can touch the thermistors with their hands, please carefully warn them not to touch the thermistors.
Store them in locations where the temperature is 10°C to +40°C and the relative humidity is 75% or below, avoid environments where
there are sudden changes in temperatures, direct sunlight, corrosive gas, grit, or dust, and keep them packed in a manner where no
loading stress is applied in order to avoid deterioration and damage. (please use them within six months.)
When sealing thermistors, please do so upon first considering the type, quantity, hardening conditions, and adhesiveness of the seal-
ing material and confirming its reliability.
Avoid powerful vibrations, impact (such as by dropping), pressure, etc. on thermistors that exceed the prescribed levels.
Do not use them for long periods of time in environments with a relative humidity of over 85%. (this excludes cases where countermea-
sures have been taken.)
Do not use them in the following environments. (this excludes cases where countermeasures have been taken.)
・Corrosive gases (Cl2, NH3, SOx, NOx, etc.)
・Environments with highly conductive substances (electrolytes, water, saltwater, etc.)
・Environments with acid, alkali, or organic solvents
・Dusty areas
Please observe the following precautions when attaching them to substrates as failure to do so may result in destruction or malfunction.
・Do not let the substrates get warped or twisted at any time during the soldering.
・The landing size must be even on both the left and right sides.
・Do not use items that have been dropped or detached.
・Do not allow the adherence of more solder than needed.
Reflow mounting is recommended with NTC thermistors, and not flow (dip) mounting.
Attaching or making corrections with a soldering iron is not recommended as it can lead to troubles such as significant distorting due to
thermal shock or cracking. If a soldering iron must be used, it should be 20W or below with the temperature of the tip at 350°C or
below, and at a maximum of 5 seconds of soldering time. Also, do not let the tip of the soldering iron come in direct contact with the
chips.
Please use a substance such as resin that does not generate hydrogen (H2) when forming insulation film over chips.
Please contact our sales offices when considering the use of the products listed on this catalog for applications, whose performance
and/or quality require a more stringent level of safety or reliability, or whose failure, malfunction or trouble could cause serious damage
to society, person or property ('specific uses' such as automobiles, airplanes,medical instruments, nuclear devices, etc.) as well as
when considering the use for applications that exceed the range and conditions of this catalog.
Please note that we are not responsible for any damages or losses incurred resulting from the use of these products that exceeds the
range and conditions of this catalog or specific uses.
Please take appropriate measures such as acquiring protective circuits and devices that meet the uses, applications, and conditions of
the instruments and keeping backup circuits.

NTC thermistors
Commercial grade
CHARACTERISTICS OF NTC THERMISTORS
NTC(Negative Temperature Coefficient) thermistors are
manufactured from sintered metal oxides. Each thermistor
consists of a combination of two to four of the following materials:
manganese, nickel, cobalt and copper. NTC thermistors are
semiconductor resistors that exhibit decreasing
resistancecharacteristics with increasing temperature. TDK
thermistors have low thermal time constants which result in
extremely high rates of resistance change to accurately track the
temperature.

BOARD DESIGN
When attached to NTC substrate thermistor, amount of silver used
(fillet size) has direct impact on NTC thermistor after mounting.
Thus, sufficient consideration is necessary.
Set of land dimensions
(1) As the stress rises in the NTC thermistor owing to the increase
in silver, breakage and cracks will occur. Cause including crack, as
caution on board land design, configure the shape and dimensions
so that the amount of silver is appropriate.
If you installed 2 or more parts in the Common Land, separated by
a solder resist and special land of each component.
Dimensions shape
(2) When peak levels panning-at soldering is excessive, by solder
contraction stress, mechanical-thermal stress causes a Yasuku
chip crack.
In addition, when the peak level is underestimated, terminal
electrode fixed strength is insufficient. This causes chip dropouts
and may affect circuit reliability.
Representative example of the panning of peak levels is shown in
the following.

CLEANING
(1) If cleaning liquid is inappropriate, residues and other foreign
body of fluxes builds up on NTC PTC surface, and can degrade the
performance of NTC thermistor (particularly the insulation
resistance).
(2) Wash conditions may compromise performance of NTC
thermistor if they are improper (wash due, wash excess).
2-1) For wash due
(a)By substance of a system in flux residue halide, metal including
terminal electrodes may experience corrosion.
(b)Substance of a system in flux residue halide builds up on NTC
PTC surface, and reduces the insulation resistance.
(c) Soluble flux makes comparisons of colophony series flux, and
there is event with trends of significant (1) and(2).
2-2) For excess wash
(1) Owing to lavage, NTC PTC surface deteriorates, and reduces
performance of NTC thermistor.
(2) In ultrasonography, when output is passed, substrate resonates
size, and crack occurs in body and sprang of NTC thermistor in
vibration of substrate. Since this may reduce the strength of the
terminal electrode, please note the following conditions.
Output Ultrasound output
Frequency Ultrasonic frequency
Cleaning time Ultrasound cleaning time
2-3) Concentration including halogen that when cleaning liquid to
pollution, when you released is higher, and may cause similar of
results into wash due.
SUBSTRATE HANDLING AFTER COMPONENT
MOUNTING
(1) When substrate is divided, a flexible so that show in following
diagram to substrate, and is given by stress including twist, as there
is possibility that crack occurs of NTC thermistor, please check that
stress is within acceptable limits.
(2) During each substrate operational check, push pressure with
contact failure of check pin of boards checkers of check pin may be
toned up to be prevented. As substrate is bent under loading, NTC
thermistor is broken owing to stress. There is also the possibility that
solder on the terminal electrode will peel off. Follow the diagram for
reference, and check that the substrate bends, please.
SINGLE-PART COMPONENT HANDLING
(1) To drop impact, as there is possibility that breakage and crack is
entered, do not NTC thermistor that(1) NTC thermistor falls.
(2) At stacking storage after implementation and treatment of
substrate, corner of boards is regarded as NTC thermistor. Please
be careful, as there is the possibility that breakage and cracks will
occur on impact.

INITIAL RESISTANCE
Thermistor resistance is a function of absolute temperature as indicated by the following relationship:
............................................................ (1)
Here R0, R(k) are the respective resistance values when the surrounding temperature is T0, T(K). B is the thermistor constant(B con-
stant below).
B CONSTANT
The B constant is found from the following equation:
....................................................... (2)
This B characteristic is indicated by the slope of the linear plot of log R-1/T inverse absolute temperature.
The B constant value is generally in the vicinity of 2500K to 5000K. B constant values of 3000K to 4000K are frequently used for measure-
ments.
Resistance-temperature characteristics (Fig.1)
TEMPERATURE COEFFICIENT
The relationship between temperature coefficient
and B becomes:
............................................. (3)
The negative sign of the temperature coefficient indicates that the temperature coefficient decreases as both thermistor resistance and
temperature rise. If B is taken as 3400K, the temperature coefficient found at 20°C (293.15K) becomes –4%/°C.

HEAT DISSIPATION COEFFICIENT
Temperature rises due to thermal energy formed as electrical current flows through the thermistor. The thermistor temperature T0 is then
related to the surrounding temperature Ta and the electrical input W:
W=k(T0–Ta)=V•I(mW) ............................................................ (4)
.............................................................. (5)
This k value is the heat dissipation coefficient, which represents the additional electrical power (mW/°C) needed to raise the thermistor
temperature by 1°C. This heat dissipation coefficient varies with changes in the measurement and environmental conditions. When a
thermistor is used for temperature measurement, it is naturally important to lower the applied electrical current as much as possible in
order to reduce measurement error resulting from self heating.
VOLTAGE - CURRENT CHARACTERISTIC
The voltage - current characteristic indicates the drop in voltage as electrical current through the thermistor is gradually increased.
Voltage-current characteristics (Fig.2)
HEATING TIME CONSTANT
The time period required to heat up a thermistor from a certain temperature T0 over a target temperature rise is called the heating time
constant. Various types of heating time constants are indicated by the symbols shown in Table 1 as determined by the percent change
from T0 toward the target temperature. The standard change is typically taken to be 63.2%.
Thermal time constants (Fig.3)
Table 1 Heating time constant and temperature change ratio
PERMISSIBLE OPERATING CURRENT
This is the maximum load current limit below 1°C temperature rise due to thermistor self-heating.
It's possible to express it in the following system.
Maximum allowed current [mA] ＝ √（Heat dissipation constant[mW/°C] ÷ Resistance[] )
