THERMISTOR

"Thermistor" is the generic name given to

thermally sensitive resistors.

Negative temperature coefficient thermistor

is generally called as thermistor. Thermistor

is a semiconducting ceramic resistor

produced by sintering the materials at high

temperature and made mainly from metal 

oxide. 

Depending on the manufacturing method

and the structure, there are many shapes

and characteristics for various purposes

such as temperature measurement, 

temperature compensation and etc.

The thermistor resistance values, unless

otherwise specified, are classified at a

standard temperature of 25

C.

B constant is calculated from the resistance 

values at 25

C and 85

C.

The resistance of a temperature is solely a function

of its absolute temperature. Since electrical power

being dissipated within a temperature might heat

above its ambient temperature and thereby reduce

its resistance,  it is necessary to test for resistance

with temperature. The resistance so measured is

called RT, which means the resistance at essentially

zero-power.

The mathematical  expression which relates the

resistance and the absolute temperature of

a thermistor is as follows:

Where:

T

2

B is a constant which depends on the

material of the thermistor

Unless otherwise specified,all values of B are

determined from measurements made at 25

C and

85

C.

The temperature coefficient of resistance

 is expressed in the follow ing equation: 

100 (%/ 

C)

Resistance -Temperature Characteristics

Dissipation factor (

) is power in milliwatts

a specified environment.

thermistor to change 63% of the difference between

its initial and final temperature. Measured with

thermistor suspended by its leads in specified

environment.

HT thermistors are entirely new type of thermistor

for surface mounting (by reflow soldering) and were

acquired from advanced technology.

Our HT thermistors are adapted metal electrodes

packaged in a resin mold, unlike conventional chip

thermistors, and can offer 

2% tolerance for a

resistance value at 25

C.

HT series (SMD Thermistor) is not only compact-

surface mounting type but also highly accurate and

reliable.

POWER

THERMISTOR

The POWER THERMISTOR is a device for

suppressing inrush current to an electric

circuit. Circuits including electric bulbs or

capacitors induce a inrush current more

than 100 times the normal current when the

circuit switch is turned on. The POWER

THERMISTOR in the circuits protects

electric equipments from being damaged

by limiting the inrush current.

MARK    is a NEW POWER THERMISTOR

featuring smaller size and larger energy

capacity to meet severe requirements in

inrush current suppression.

There is the tendency of miniaturization in

low power switching power supply, and

MARK    is effectively applicable for the

needs, though the comparatively larger

sized fixed resistors (ceramic coat) are

used now.

Application

How to use the power thermistor

The power thermistor will suppress inrush current

which is caused by a capacitor, filament for a bulb,

inverter for fluorescent lamp, a heater and etc., also

will control fan motor speed of cooler for electric

circuit.

Especially MARK    was developed to use for power

supply of TV, VCR instead of cement resistor.

Accordingly, suitable thermistors are 6D-22, 5D-18

and 8D-18, and if we consider in the points of small

time constant which means a small size and large

effect for suppressive current which means large

rated zero-power resistance, 8D-18 is the most

suitable one.

Use the following circuit in the power supply for 100V

and 200V.

The most suitable power thermistor for the above

circuit is required to fulfill the following terms and

conditions.

1. The permissible current at ambient temperature of

    55

C should be over 2A.

2. The thermistor resistance for suppressive current

    which becomes below 30A should be over 4.2

    ohm from the under-mentioned formula.

Thermal time constant

If ambient temperature of a thermistor is changed

to T

1

 from T

2

 suddenly, temperature of the thermistor

changes slowly.

The time constant means the time when temperature

of the thermistor reaches 63% of the temperature

difference.

Maximum permissible current

If the maximum permissible current flows to a

thermistor at 25

C, temperature of the thermistor

Residual resistance

If current is flowed through a thermistor, any heat

will be generated in the thermistor by which its

resistance will be decreased, however, a decrease

of a resistance will be stabilized at a saturation

resistance value which is determined by impressed

electric power and a dissipation constant. The

residual resistance value means maximum

saturation resistance value when the maximum

permissible current is flowed through the thermistor.

Temperature coefficient

The temperature coefficient of a thermistor is

expressed by the following equation ;

Dissipation factor

If small voltage is applied to a thermistor, small

current will flow which produce enough heat in the

thermistor. Dissipation factor is electric power

which make 1

C raise by heat in a thermistor.

Resistance-temperature characteristics

The theoretical characteristics of a thermistor is expressed by following equation.

P is applied electric power.

t is rised temperature of the thermistor.

TRANSIENT VOLTAGE SUPPRESSOR

VRD

VRD is a transient voltage

suppressor used for protecting electric

circuits from surge voltage and thus

preventing breakdown.

VRD has superior surge suppression

characteristics, such as extremely fast

response time, very low clamping voltage,

and high surge capacity. Unlike metal oxide

varistors, VRD does not have characteristics

to change with surge variations within the

rated capacity. This feature comprises

another superior characteristics of the VRD

as a transient voltage suppressors.

Electrical characteristics

Figure 1 shows the electrical characteristics. Bipolar

type has almost symmetrical breakdown Voltage (V

B

)

Surge capability

Allowable surge capability (Pm) is determined by the

following equation:

     Pm

Ip

V

C

     Ip:Peak current 

     Vc:Maximum clamping voltage

The allowable surge capability (peak pulse power) of

VRD is shown in following Figure 3 and the surge ca-

pability derating characteristics are shown in Figure 6. 

Surge suppression characteristics

Power derating

When EXP waveform is applied to the circuit

below, the surge suppression waveform shown in the

figure 5 can be observed. 

Surge waveform

There are many types of surge waveform depending

on the source of the surge. For the VRD surge

suppression characteristics test, the EXP waveform

shown below is used. The EXP waveform is shown as

ta / tb depending on the time width, however 10/1000

waveform is used as the standard test waveform.

The reverse breakdown voltage of the ZD type is 200

Volts or more at 10

A DC.
