Product Material:
The heating core is made from barium titanate-based (BaTiO3) PTC thermistor ceramic. Depending on the operating temperature, heat-transfer requirements, and assembly design, it can be combined with alumina (Al2O3) insulating parts, aluminum heat-transfer components, high-temperature insulation, and lead wires. Aluminum nitride (AlN) or zirconia (ZrO2) ceramic options can be evaluated for projects that require improved thermal performance or mechanical strength.
Functional Features:
As the ceramic temperature rises, its electrical resistance increases and the power input gradually decreases. This allows the heater to maintain a more stable temperature while reducing the risk of continuous overheating. Voltage, target temperature, dimensions, lead wires, and insulation structure can be adjusted to suit the equipment.
Applications:
Used in hair straighteners and curling irons, laboratory sample heaters, compact hot-melt and sealing tools, portable liquid-warming devices, temperature-controlled incubation equipment, anti-condensation modules, and wearable heating devices.

Lead Time:

This PTC ceramic heating element is made for compact equipment that needs steady, controlled heat. It uses barium titanate-based PTC ceramic and is suitable for hair styling tools, laboratory sample heaters, anti-condensation modules, and portable warming devices. As the ceramic heats up, its resistance increases and power draw falls, helping limit temperature overshoot and unnecessary full-power operation.
The heater uses a layered construction, with each material serving a specific purpose:
The final combination depends on the voltage, target temperature, available space, and the way heat needs to reach the working surface. Aluminum nitride (AlN) or zirconia (ZrO2) ceramic parts can also be considered when a project has higher thermal or mechanical requirements.

This heater is intended for equipment that needs localized heat within a limited installation space. Typical uses include:
For medical or body-worn equipment, material safety, electrical protection, and certification requirements must be confirmed as part of the complete device design.
As the heater approaches its designed temperature, resistance rises and power consumption falls. This makes PTC ceramic well suited to equipment that spends more time holding temperature than heating from cold.
The material responds directly to its own temperature, helping reduce the excessive heat rise that can occur when a standard resistance heater remains at full power.
The ceramic body, insulation, and heat-transfer parts can be assembled into a thin or strip-shaped unit that fits inside small housings.
Power output changes with the heater temperature and surrounding heat loss. This allows the element to respond naturally as the equipment warms up or the ambient conditions change.
For applications with moderate temperature accuracy requirements, the PTC effect can simplify power control. Sensors and independent over-temperature protection may still be required by the finished equipment.

These figures are reference values. Final specifications depend on the heater size, required power, installation method, and agreed test conditions.
| Parameter | Reference Specification | Selection Notes |
|---|---|---|
| Heating Material | Barium titanate-based PTC ceramic (BaTiO3) | The formulation is selected for the required temperature range. |
| Insulation Material | Alumina ceramic or high-temperature insulation | Selected to suit the voltage and installation structure. |
| Heat-Transfer Part | Aluminum heat spreader or heat-transfer component | Configured around the required surface temperature distribution. |
| Reference Curie Temperature | 160–230°C | The Curie temperature is not necessarily the continuous operating temperature. |
| Operating Voltage | 100–240V AC, customizable | Each voltage requires a matching resistance and structural design. |
| Reference Heat-Up Performance | 180°C in less than 30 seconds | Measured under specified voltage, size, and test conditions. |
| Reference Dielectric Withstand Test | 3750V AC / 0.5mA / 1 second | Must be confirmed for the final insulation structure. |
Important: The 100–240V range refers to available design options. It does not mean that one heater can be connected directly to every voltage in that range.
| Heating Technology | How It Is Controlled | Best Suited For | Typical Uses |
|---|---|---|---|
| PTC Ceramic Heater | Power falls as the ceramic temperature rises. | Continuous warming and reduced temperature overshoot | Compact warming devices and anti-condensation modules |
| MCH Ceramic Heater | Usually paired with a sensor and external controller. | Fast heat-up and higher power density | Soldering iron cores and rapid-heating tools |
| Resistance Wire Heater | Mainly relies on an external temperature controller. | General heating over a larger area | Air heaters and general heating equipment |
| Aluminum Nitride Ceramic Heater | Uses a precision heating circuit with external control. | Fast heat transfer and improved temperature uniformity | Semiconductor and precision thermal equipment |
PTC ceramic is a practical choice when the main requirement is steady warming in a compact space. MCH or aluminum nitride heaters may be a better fit when rapid heat-up, higher power density, or precise external control is more important.
No. It is a heating component installed inside the customer’s equipment. The power supply, control panel, housing, and complete-device safety protection are normally supplied separately.
Please provide the installation space, rated voltage, target temperature, ambient temperature, contact surface, expected heat-up time, and estimated order quantity. If an existing sample is available, cold resistance, power, lead arrangement, and operating conditions are also helpful.
Usually not. The ceramic formulation, resistance, size, and internal structure must be designed for the intended voltage. Applying a different voltage can significantly change power and heating performance.
The final surface temperature also depends on voltage, heat loss, contact material, mounting pressure, and ambient temperature. If the first sample does not meet the target, the resistance, material formulation, heat-transfer structure, or mounting method can be reviewed.
That depends on the required accuracy and safety level of the finished equipment. The PTC effect helps regulate power, but it does not replace a sensor, controller, or independent over-temperature protection in every application.
Common checks include dimensions, cold resistance, heat-up curve, stabilized temperature, dielectric withstand, insulation, lead connection, and heat distribution after installation. Additional tests can be agreed for the end application.
Stable contact is normally needed for efficient heat transfer. Gaps, mounting pressure, thermal interface materials, and the fixing method all affect heat-up time and final temperature. Providing the installation design helps us recommend a suitable heat-transfer and insulation structure.
