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:

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)

Dissipation factor (
) is power in milliwatts

thermistor to change 63% of the difference between
its initial and final temperature. Measured with
thermistor suspended by its leads in specified
environment.

AT THERMISTOR
The AT thermistor is a high-precision thermal
sensing device featuring extremely small
B-value tolerance and resistance.
When used as a temperature gauge, the AT
thermistor requires no adjustment between
the control circuit and the sensor.
This insures temperature precision of
0.3
C.
Temperature indicators and control instruments
are now available for use with the thermistor.

ET THERMISTOR
The ET thermistor is smaller version of the AT thermistor.
Its fast response time and high reliability makes it
Particularly suitable for use in medical equipment
and thermometers. Manufactured by full-automated
production line, all ET thermistors have identical size and
that makes it possible to assemble sensors automatically.

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.

FT THERMISTOR
The FT thermistors, the highly reliable thermistors, are
characterized by their fast response time, which was
made possible by the miniaturization of the thermistor
dimensions. FT thermistors are also heat-resistant type.
FT thermistors are the most excellent products of today
,
s
chip thermistors manufacturing.

SMD type chip
Chip thermistors are specially processed, highly
reliable thermistors.
They can be face-bonded to act as thermal
compensators for ICs and they are manufactured
in sizes down to 1 square mm, they can also be
used to detect temperature with relatively small
time constants.

GT THERMISTOR
GT thermistor is combined both superior feature of
BT thermistor and ET thermistor as fast response
time, high reliability, wide category temperature
range, high moisture proof, high accuracy and
reasonable price.
GT thermistor is made up of a high quality
thermistor element and the lead wire is connected to
the thermistor element by alloyed technology, and
glass coating for the thermistor element.

CT THERMISTOR
The CT thermistor is a thermal sensor in a DO35
package. Similar to the BT thermistor, it is highly
reliable and offers a wide operating range of
50
C
to 250
C. It is primarily used in home electric
appliances
and features a competitive price for
full-automated manufacturing system.

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
rises to 200
C, (160
C). When ambient temperature is
above 25
C, the maximum permissible current shall be
over reduced as the maximum permissible current
reduction curve.

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.
Taping
One of standard taping is as shown in Figure.
