1. Product Name

PTC is the English abbreviation for positive temperature coefficient thermistor

2. Working principle

The internal heating element of the PTC heater is a positive temperature coefficient thermistor, and its resistance value shows a stepwise increase as the temperature of the PTC thermistor body increases. The higher the temperature, the greater the resistance value.

3. Product Advantages

Dry burning, energy-saving, long service life, no open flame, suitable for low-power heat dissipation, preheating, and dehumidification of micro devices.

4. Power selection

Directly connected to the rated voltage, both AC and DC, without positive or negative electrodes.

Taking a 12V heating element as an example, it can be connected to AC and DC 12V. The power current must be greater than the maximum heating current of the heating element, otherwise the heating element cannot be carried.

5. About power

After the PTC heating element is powered on, the power varies from low to high, then to low, and finally stabilizes. Stable power is directly related to heat dissipation, with fast heat dissipation and high power consumption. Our target is maximum dissipated power, and the actual power used is smaller than the maximum dissipated power.

It is strictly prohibited to use in corrosive, flammable, and explosive environments, to throw into water, to strike, and to open holes.

Multiple heating pads with the same voltage can be connected in parallel, and multiple heating pads can be installed side by side. The heating pads cannot overlap each other, otherwise the heat will be offset.

Multiple heating pads should be used in parallel, and the more heating pads, the greater the power.

A decrease in power supply voltage will result in longer heating time and lower power, but the temperature remains basically constant (with a slight decrease in temperature).

6. Purpose

Batteries, security, medical, scientific research, industrial motors, aerospace, and other electronic and electrical low-power heating, preheating, dehumidification, and insulation.

The application is quite extensive, such as electric mosquito coil heating element, shoe warmer heating element, incense burner heating element, heater heating element, electric cup heating element, water dispenser heating element, coffee machine heating element, yogurt machine heating element, automotive component insulation, diesel alcohol heating, instrument heating and dehumidification, electromagnetic valve antifreeze, distribution cabinet dehumidification and dehumidification, electronic component constant temperature preheating, portable heating element, and many other applications that can be developed.

Note: The temperature marked here is the maximum temperature limit for the surface temperature of the heating element in the empty burning state, and this temperature does not represent the temperature during use; The use temperature is controlled by the environment and on-site heat absorption; The surface temperature limit and usage temperature of air burning are completely different;
