II How PTC Thermistorworks
Thermistors for heaters require safety and power saving
performance. The PTC quickly heats up when current flows through
it. The Thermistor reaches the heating temperature evenly
throughout its entire structure. The heating temperature can be
controlled by adjusting the construction of PTC's material make-up.
In addition, because PTC THERMISTOR maintains a constant
temperature thanks to a balance between heat generation and heat
dissipation, it will not exceed the heating temperature.

VI Design Considerations Of The PTC Thermistor for Standard Heaters
When selecting a PTC, you should consider the following factors:
- Thermal Connections
- Switch Temperature (Ts)
- Resistance at 25 °C (R 25)
- Surface Area
- Maximum Voltage (Vmax)
Figure 12: Resistance vs. Temperature for a PTC
Ceramic PTC heaters are usually most efficient when they are flat
and thin and have a smooth surface finish. For a PTC to operate as
a heater, it must have a way to dissipate its heat to the medium,
either by convection (air or liquid flow) or conduction. One common
method is to use a spring contact as both the electrical and
mechanical connection (See Figure 13). One advantage of this
"clamping" technique is that it allows stress-free thermal
expansion. Other techniques involve using electrically conductive
epoxies or solder joints to connect the PTC to the heat spreader.
The switch temperature (Ts in Figure 12) is very important because,
in most heater applications, the maximum surface temperature of the
PTC is just a few degrees above its switch temperature. Thus, the
maximum temperature of the medium to be heated is directly related
to the switch temperature Ts of the PTC.
Figure 13: PTC Heater - Transfer
The R25 of the PTC heater is typically not the most important
design factor. It should not be so low that it causes inrush
current problems, but not so high that there is not enough power
available to heat the PTC to its switched condition. The PTC cold
resistance will, however, influence the heat-up rate of the medium
since a lower resistance allows for higher initial I2R heating.
The surface area of the PTC heater influences the heat-up and
cool-down rates of the medium as well as the power dissipated.
Multiple PTCs are often used in heater design to obtain the desired
results. As with any PTC thermistor application, the heater design
should not exceed the maximum recommended voltage ratings. The
maximum Voltage (Vmax) specified on the MS data sheets is for DC or
60Hz AC only.

XI PTC Heating Element Overview Of The PTC Thermistor
PTC heating element refers to the automatic temperature control PTC
ceramic heating element, a special ceramic material. Its production
process is as follows:
Weighing milling >> >> >> granulated pre-sintered
Sintered molding >> >> >> >> resistance on
the electrode separation
>> Crimping package assembly >> >> >>
withstand voltage test of trade marks
>> >> Final testing resistance detection >>
Packaging >> storage
PTC heating thermostat heating principle is: when the PTC heating
element is energized, because the room temperature resistance is
small, so the starting current is large, make the PTC heating
element heat up quickly, leading to a rapid increase in resistance
value itself into the transition zone, which when the current
through the PTC heating element is very small, so that PTC heating
element surface temperature is always maintained constant, the
temperature only with PTC heating element of the Curie temperature
and applied voltage, and substantially independent of the ambient
temperature.
