Feature:

1. Core Performance Characteristics (Core Advantages)

• Self-Limiting Temperature & High Safety: It has an inherent self-limiting temperature characteristic. When the temperature reaches the Curie point (generally 80℃-300℃, adjustable by material formula), the resistance will increase sharply (up to 10⁴-10⁶ times), and the heating power will drop rapidly to maintain a constant temperature. There is no risk of overheating or open flame, even if the air duct is blocked or the fan fails.
• Rapid Heating & High Thermal Efficiency: The thermal response speed is fast. It can reach 90% of the rated power within 3-5 seconds after power-on, and the surface temperature rises stably. The heat conversion efficiency is as high as 95% (traditional resistance wire heaters are about 70%-80%), which can quickly provide hot air without energy waste.
• Stable Operation & Long Service Life: The heating process has no thermal expansion and contraction caused by repeated heating/cooling, and no oxidation or aging of the heating body. Under normal working conditions, the service life can reach 50,000-100,000 hours (equivalent to 5-10 years of continuous use), which is 3-5 times that of traditional resistance wire heaters.
• Energy Saving & Intelligent Adaptability: The power automatically adjusts with the ambient temperature. When the ambient temperature is low, the power is high to speed up heating; when the temperature is close to the set value, the power is reduced to keep warm. This "on-demand heating" mode can save 20%-30% of energy compared with fixed-power heating elements.

2. Key Performance Parameters (Technical Indicators)

• Rated Power: Generally 50W-5000W, which can be customized by combining multiple PTC chips. For example, household heaters usually use 800W-2000W, while industrial equipment can use 3000W-5000W.
• Curie Temperature (Tc): The critical temperature for power attenuation, usually 80℃-300℃. It is selected according to the application scenario—for example, bathroom heaters use 100℃-150℃, and industrial drying equipment uses 200℃-250℃.
• Working Voltage: It is compatible with AC and DC voltages. Common specifications include AC 110V/220V/380V (for household/industrial use) and DC 12V/24V/48V (for automobiles, RVs, and outdoor equipment).
• Thermal Resistance: The thermal resistance between the PTC chip and the heat dissipation surface is ≤0.5℃/W. Lower thermal resistance means faster heat transfer and higher efficiency.
• Insulation Performance: The insulation resistance between the heating body and the shell is ≥100MΩ (under 500V DC), and it can withstand a voltage of 1500V AC for 1 minute without breakdown, ensuring safe use in humid environments.

3. Environmental Adaptability (Applicable Conditions)

• Temperature Range: It can work normally in the ambient temperature range of -40℃ to 80℃. In low-temperature environments (-40℃), there is no problem of "difficult startup" of traditional heaters; in high-temperature environments (80℃), the self-limiting temperature function can still play a role.
• Humidity Resistance: The protection level can reach IPX4 (splash-proof) or IPX5 (water-jet proof) through structural design, which is suitable for humid scenarios such as bathrooms, kitchens, and ships.
• Vibration Resistance: It has good mechanical strength and can withstand vibration of 10-500Hz (acceleration ≤10G), which is suitable for mobile scenarios such as automobiles, RVs, and engineering vehicles.

Application:

1. Household and Daily Electrical Appliances (Core Application Scenario)

• Heating equipment: Tower heaters, baseboard heaters and bathroom-specific heaters are typical representatives. They adopt honeycomb PTC heating elements, which can blow out hot air within 3-5 seconds after startup, eliminating the need for long waiting. When the temperature reaches the designed value (e.g., 80℃), the power will automatically decrease to maintain a constant temperature. Even if the air outlet is blocked or the fan malfunctions, there will be no overheating and fire hazards. They are especially suitable for families with the elderly and children, as well as humid bathroom environments.
• Air treatment appliances:
  • Heated humidifiers: Use PTC elements to heat water and generate pure steam, featuring high humidification efficiency and sterility, which avoids water pollution problems of traditional humidifiers.
  • Air coolers (with heating function): Rely on PTC elements to provide stable heat sources when switching to the heating mode in winter, realizing "one machine for two uses".
  • Fresh air systems/air curtains: Preheat the cold air flowing in from the outside to prevent a sudden drop in indoor temperature and improve the sense of comfort.
• Kitchen appliances:
  • Instant hot water dispensers/water purifiers: Equipped with PTC heating tubes, they can achieve instant heating in 3 seconds, avoiding "reboiled water" caused by repeated boiling. They can also maintain a constant temperature for a long time, with a service life of up to 50,000 hours.
  • Smart rice cookers/electric kettles: PTC elements are used in the heat preservation stage to control the temperature accurately (with an error of ±1℃), preventing burning due to dry heating and reducing energy consumption at the same time.
• Personal care and small daily electrical appliances:
  • High-end hair dryers, hair straighteners and curling irons: Adopt ceramic-coated PTC, which can heat up quickly with a temperature fluctuation of less than ±3℃, avoiding hair damage caused by local overheating. Some products also use PTC's temperature stability to achieve intelligent temperature adjustment according to different hair types.

2. Automotive Industry (Fast-Growing Application Scenario)

• Cabin heating: NEVs use PTC heaters as the core heating component of the air conditioning system. Compared with traditional resistance wire heaters, PTC can heat the air in the cabin to a comfortable temperature (e.g., 22-25℃) in 2-3 minutes after the vehicle is started, and the energy consumption is reduced by about 30%, effectively extending the driving range.
• Seat and steering wheel heating: Built-in thin-film PTC heating sheets in car seats and steering wheels. The heating sheet is only 0.5-1mm thick, which does not affect the comfort of the seat or the grip of the steering wheel. It can quickly heat up to 38-42℃ and maintain a constant temperature, improving driving comfort in cold weather.
• Window defrosting and defogging: Small PTC heating modules are installed at the bottom of the front windshield and rear window. They can quickly melt the frost and fog on the window surface in 1-2 minutes, ensuring clear vision for the driver and improving driving safety.

3. Industrial and Commercial Fields (Professional Application Scenario)

• Industrial drying equipment: Used in small drying ovens, textile drying machines and plastic processing equipment. PTC heating elements can maintain the internal temperature of the equipment within a fixed range (e.g., 50-120℃) with an error of less than ±2℃, ensuring the consistency of product quality (such as the moisture content of dried textiles and the forming effect of plastic products).
• Commercial air conditioning and heating: Installed in central air conditioning systems of shopping malls, hotels and office buildings (especially in areas with no central heating). PTC modules can be flexibly combined according to the area of the space to adjust the heating power, realizing "on-demand heating" and reducing the operation cost of commercial buildings.
• Medical and laboratory equipment: Used in constant temperature incubators, medical drying cabinets and laboratory reagent storage cabinets. PTC heating elements have no open flame and low electromagnetic interference, which can avoid affecting the activity of biological samples or the accuracy of reagents, meeting the strict environmental requirements of the medical and laboratory fields.
