## **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.
## **REMINDERS**
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 sealing 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 countermeasures 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.

**Product compatible with RoHS directive Compatible with lead-free solders**
## **Commercial grade**
## **Overview of the NTCG series**
## **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.

The B constant indicates the magnitude of a change in a zero-load resistance value to a temperature, and is obtained based on arbitrary two temperatures in resistance-to-temperature characteristics.
## B constant calculation formula
InR1–InR2 B= – (1/T1) (1/T2)
B: B constant (K)
T1: Arbitrary temperature (K)
T2: Arbitrary temperature different from T1 (K)
R1:Zero-load resistance value at temperature T1( )
R2: Zero-load resistance value at temperature T2( )
Each temperature is measured in absolute temperature. 0°C=273.15K

## **Product compatible with RoHS directive Compatible with lead-free solders**
## **Attention in the board design**
## **BOARD DESIGN**
(2) When peak levels panning-at soldering is excessive, by solder contraction stress, mechanical-thermal stress causes a Yasuku chip crack.
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.
In addition, when the peak level is underestimated, terminal electrode fixed strength is insufficient. This causes chip dropouts and may affect circuit reliability.

## **NTC thermistors**
**Product compatible with RoHS directive Compatible with lead-free solders**
## **Commercial grade**
## **Description and definition of terms**
## **INITIAL RESISTANCE**
Thermistor resistance is a function of absolute temperature as indicated by the following relationship:
1 1 R=R0 • expB – ............................................................ (1) ( T T0 ) Here R0, R(k ) are the respective resistance values when the surrounding temperature is T0, T(K). B is the thermistor constant(B constant below). | **B CONSTANT** The B constant is found from the following equation: 2.3026(logR–logR0) B= T1 – T10 ....................................................... (2)
The B constant is found from the following equation:
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 measurements.

## ~~|~~ **TEMPERATURE COEFFICIENT**
The relationship between temperature coefficient and B becomes: 1 dR B = R • dT = – T[2] 100(%/°C) ............................................. (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)
**==> picture [234 x 18] intentionally omitted <==**
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.

## **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%.

## a **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[ ] )
