Working Principle: the Internal Heating Element of the PTC Heater Is a Positive Temperature Coefficient Thermistor, and Its Resistance Value Shows a Step Wise Increase with the Increase of the Temperature of the Ptc Thermistor Body. the Higher the Temperature, the Greater the Resistance Value.

PTC Features 
1. Safety: PTC Products Have Constant Temperature Heating, No Open Flames, High Heat Conversion Rate, and Are Minimally Affected by Power Supply Voltage
2. Energy Saving: PTC Products Have Automatic Energy-saving Characteristics. When the Heater Raises the Ambient Temperature, Its Power Gradually Decreases to Only 90%, 80%, or less of the Rated Power.

PTFE High-Temperature Resistant Wire, With A Lead Length Greater Than 70mm, Surface Constant Temperature, And An Error Of ± 10℃.
Reminder: It Is Strictly Prohibited To Remove The Yellow Film On The Surface, Soak In Water, Bend Or Open Holes, And Dry Burn Is Allowed. For Example, 12V, 60 °C Refers To A Voltage Of 12V, And The Surface Of The Heating Element Is Dry Burned At A Constant Temperature Of About 60 Degrees Celsius. When Heating Up, It Is 2.5 Watts. After The Heating Element Is Kept Constant, The Resistance Increases And The Current Decreases, Resulting In A Decrease In Power To About 1 Watt.
