2. Surface Temperature: 80°C~300 °C , the temperature tolerance less than ±5°C

3. The lead wire, fiber glass sleeve, insulate film and shells can customize.

                           

Part.1

After switching on, the power is large, and then decrease, finally it become steady state. The steady state power changes with applied conditions. Faster is the heat conduction, higher is the steady state power; higher is the surface temperature, higher is the power.

                           

Part.2

The surface temperature of  PTC heating element can be controlled by itself, control circuit may be omitted in most appliances.

                           

Part.3

Our PTC products are high reliable, long lifetime, but if they are assembled improperly, the power or temperature may be instable.

                           

Part.4

Parallel connection is necessary for two or more PTC connection.

PTC ceramic heater knowledge：

1. PTC ceramic heating elements have special functions of constant temperature, temperature regulation and self-controlling temperature

When AC or DC voltage is applied to the PTC element, the resistivity is very low below the Curie point temperature, and the temperature rises quickly. Once the Curie point temperature is exceeded, the resistivity suddenly increases, causing its 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 Curie temperature of the PTC element can be adjusted by formula according to different temperature requirements.

2. Non-burning, safe and reliable

The PTC element does not turn red when it is hot, and there is no open flame (resistance wire is red and open flame), and it is not easy to burn. When the ambient temperature of the PTC element exceeds the limit, its power is automatically reduced to an equilibrium value, and there is no danger of burning.

3． long life 

PTC elements are oxide ceramics, without the high temperature oxidation disadvantages of nickel-chromium wires, and without fragile phenomena such as glass quartz tubes, and have a long life.

4． Wide operating voltage range

PTC components can be used normally under low voltage (3-36 volts) and high voltage (110-380 volts). Low-voltage PTC components are suitable for various low-voltage heaters, low-temperature compensation of instruments, and various heaters for automobiles. High voltage PTC components are suitable for heating the following electrical equipment: shoe dryers, hot melt glue guns, rice cookers, electric hot shoes, electric mosquito repellents, steam combs, steam generators, humidifiers, curlers, vending machines, wind Curtain, hand warmer, tea dryer, beauty device, bottle thermostat, etc.
