The round shape Electric PTC ceramic heating element are use for round shape electric heaters which use PTC as the heating element. It is Positive Temperature Coefficient heating element, which supplies automatic constant temperature without temperature controls.
With the maturity of PTC technology, PTC thermistor heating elements have been closely related to people's daily life. In just a few decades of development, it has been widely used in light industry, agriculture, transportation, aerospace, medical, environmental protection, mining, civilian equipment and other industries. But in many domestic using field, the round ptc ceramic heating elements are using low voltage. They are suitable for all kinds of low-voltage heaters, low-temperature compensation of instruments, heaters on automobiles and computer peripherals, warm beauty instruments, circuit board PCB board heating, USB heating pads, incense burners, mosquito repellents, etc. Voltage range: 3.7VDC, 5VDC, 6VDC, 9VDC, 12VDC, temperature range: 60 ℃, 65 ℃, 70 ℃, 75 ℃, 80 ℃, 85 ℃, 90 ℃, 95 ℃, 100 ℃, and 100 ℃ ~ 265 ℃ .
Because of following advantages, they are safe and effective heating elements
1) They use PTC internal characteristics to control temperature, never over temperature.
2) The effect of changes in operating voltage on surface temperature is relatively small. When the operating voltage is doubled (or decreased by 1/2), the surface temperature rises (or falls) by about 8 ° C.
3) There is no lead wire and insulation layer for this type of product. Customers also choose our products with wires and insulation layer, or products with shells.
4) When multiple PTCs are used together, they should be connected in parallel, not in series.
5) The heating power of PTC varies greatly due to different heat dissipation conditions.
