PTC thermal ceramic heating piece PTC thermistor for heating.pdf
The characteristics of PTC ceramic heating pads are mainly reflected in its three main aspects: resistance-temperature characteristics, volt-ampere characteristics, and current-time characteristics. Among them, resistance-temperature characteristics are the most basic characteristics and the most important factor in determining the performance of PTC materials. special.
working principle:
PTC thermistor ceramic heating piece has special functions of constant temperature, temperature adjustment and self-temperature control.
When an AC or DC voltage is applied to a PTC element, below the Curie point temperature, the resistivity is very low and the temperature rises quickly. Once the Curie point temperature is exceeded, the resistivity suddenly increases, causing the current to drop to a stable value. To achieve the purpose of automatic temperature control and constant temperature, no additional temperature control circuit device is needed, and the living temperature of the PTC element can be adjusted according to different temperature requirements through formulas to achieve the required operating temperature in different application scenarios.
External structure:
There are three types of chip PTC heating element structures: double-sided electrode lead type, single-sided electrode lead type, and side electrode lead type.
| Type | Features | Advantage | Shortcoming |
| Double-sided electrode lead wire | The electrode surfaces are on the upper and lower large planes of the PTC ceramic sheet. | Simple structure, low cost, resistance can be made very small | The large upper and lower surfaces require metal contact pieces to conduct electricity, which is not as reliable as welding. |
| Single sided electrode lead wire | The two electrical contact points are on the same large plane of the PTC ceramic sheet | Can be welded, the entire heater is small in size and highly reliable | The cost is more expensive than the double-sided electrode lead, and it cannot be used to make a heating plate with a small area. |
| Side electrode leads | Two electrical contact points are on the two small sides of the PTC ceramic piece | Welding on the circuit board or welding wires on the side does not affect heat transfer | The smaller the resistance, the more difficult it is to make. The surface temperature of PTC cannot exceed the soldering temperature.. |
In order to facilitate customer installation, we also provide products with other structures, such as: PTC heating parts with insulation layer (and wires), PTC heating pieces with shell (and wires), used for water heating, hair straighteners, air heating, etc. For PTC heaters, see this link to the left.
2.Usage examples:
Heaters, air conditioning heating, clothes dryers, mosquito killers, motorcycle carburetors, car cold start preheating, electric humidifiers, moisture-proof electrical instruments, electric hot plates, massagers, thermotherapy instruments, glue guns, curling hair, Hair straightener heating, hot coffee machine, milk warmer, boiling water, water heater, steam beauty, etc. When the product terminal temperature is below 260°C, PTC heating can be used to maintain a constant temperature without temperature control. It has a compact structure and long service life, which has great advantages.
3.Usage precautions:
1) The PTC heating element has the characteristics of automatic constant temperature and does not require a temperature control system. Just energize the PTC directly.
2) When the PTC heating element is used to heat a liquid (such as water), the PTC heating element will not be damaged after the liquid is dried.
3) If the PTC heating element is used to heat cold air, the PTC heating element will not be damaged when the air is not supplied.
4) There are four electrodes for customers to choose from: electroless nickel + silver (can be welded), melt-blown metal aluminum, printed aluminum + silver, printed silver zinc + silver (can be welded), printed aluminum.
5) Long service life, if used in normal environment, the service life can reach more than 10 years. Our company's heating plate life test is at a high-quality level in China.
6) Reliable operation, using the internal characteristics of PTC to control temperature, it will never overheat.
7) Changes in operating voltage have relatively little impact on surface temperature. When the operating voltage increases by 2 times (or decreases by 1/2), the surface temperature increases (or decreases) by about 8°C.
8) When multiple PTCs are used together, they should be connected in parallel and not in series.
9) Different heat dissipation conditions make the heating power of PTC vary greatly. The faster the heat dissipation, the greater the power.
10) In general, double-sided electrode lead-out type PTC sheets are used, but for special purposes, single-side electrode lead-out and side electrode lead-out can also be used.

Note:
1) As the thickness of the PTC sheet increases, the withstand voltage and reliability increase. For products with relatively high voltage or other products that require relatively high reliability, thicker PTC should be selected.
2) PTC ceramics are fragile, and a single PTC should not be made into a large area. When a larger area is required (such as uniform heating, or increased heating power, etc.), several PTCs can be combined into a large area (with shell or insulation). and wires), see our company's products: insulation-wrapped PTC heating sheet and shell-type PTC heating element.
3) Special shapes, such as ring, hexagon, triangle, rod, ring rod, etc., can be customized according to customer requirements. Extra large sizes can be customized.
4) The price of the heating plate varies according to the specific requirements and dosage of the product
