## **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 cause smoke or fire. 

## **REMINDERS** 

- ◯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 as this may lead to staying in thermal runaway mode or the redshorting 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 within 6 months after delivery.) 

If the storage period is exceeded, the surface of the terminal electrode may be oxidized or sulfided and the resistance value may shift. 

- ◯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

## Chip NTC thermistor 

Automotive grade, for conductive glue 

**RoHS Directive Compliant Product Corresponding to conductive glue AEC-Q200** 

## **Overview of the NTCSP 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 resistance characteristics 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 

B: B constant (K) T1: Arbitrary temperature (K) 

InR1–InR2 T2: Arbitrary temperature different from T1 (K) B= – R1:Zero-load resistance value at temperature T1(Ω) (1/T1) (1/T2) R2: Zero-load resistance value at temperature T2(Ω) 

Each temperature is measured in absolute temperature. 0°C=273.15K

## Chip NTC thermistor 

Automotive grade, for conductive glue 

**RoHS Directive Compliant Product Corresponding to conductive glue AEC-Q200** 

## **Attention in the board design** 

## **BOARD DESIGN** 

## **Amount of conductive glue** 

When attached to NTC substrate thermistor, amount of conductive glue has direct impact on NTC thermistor after mounting. Thus, sufficient consideration is necessary 

Excessive amount of conductive glue during mounting can cause electrical path formation under the chip (between the lands). 

In addition, when the amount of conductive glue is excessive, the terminal electrode sticking force is insufficient, causing chip falling off, which may affect the reliability of the circuit. A typical example of the amount of conductive glue is shown below. 

## **Set of land dimensions** 

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 conductive glue is appropriate.

Excess adhesive forms a conductive path under the chip. 

The sticking force is weak, the connection is bad, and there is a risk of falling off.

## Chip NTC thermistor 

Automotive grade, for conductive glue 

**RoHS Directive Compliant Product Corresponding to conductive glue AEC-Q200** 

## **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(kΩ) 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= 1 1 ....................................................... (2) T – T0 

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 α and B becomes: 

1 dR B α= • = – ~~ｘ~~ 100(%/°C) ............................................. (3) R dT T[2] 

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) 

W k= (mW/°C) .............................................................. (5) T0 –Ta 

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.

## **■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%.

## **■PERMISSIBLE OPERATING CURRENT** 

This is the maximum load current limit below 1°C temperature rise due to thermistor self-heating. It\qs possible to express it in the following system. 

Maximum allowed current [mA] = √(Heat dissipation constant[mW/°C] ÷ Resistance[Ω] )
