I Features Of The PTC Thermistor

• Quickly heats up to desired temperature.

• Its temperature is uniform and never gets red hot, making it very safe.

• PTC's self-temperature-control effect prevents excessive heating.

• The PTC's self-temperature-control function ensures power savings.

• Users can select their desired temperatures.

• High accuracy temperature within ± 8 ℃ or less.
• High withstand voltage up to 500VAC or more.
• Complete specifications.

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.
