MOQ：1000PCS
Lead time：25days
Factory location: Zhongshan, Guangdong, China
Household appliances: heaters, air conditioning auxiliary heating modules, electric heaters, instant water heaters.
Industrial equipment: automotive air conditioning heater cores, agricultural greenhouse constant temperature systems
Power range:
Household: 200W–2000W (electric heater, clothes dryer, air fryer)
Industrial: 2000W–15kW (industrial oven, medical device disinfection, automotive air conditioning heating system)
Working voltage: 12V–480V AC/DC (global power grid compatible, error ≤±5%).
Resistance value: 10Ω–1000Ω (accurately matched by voltage and power, error ≤±3%).
Working temperature:
Conventional model: continuous and stable operation of 80°C–250°C (self-limiting temperature characteristics, automatic power reduction to prevent overheating).
High temperature model: short-term tolerance of 350°C (customized heat dissipation structure and high-temperature ceramic coating are required).
Material:
PTC chip: barium titanate-based ceramic (Curie temperature 60°C–300°C adjustable, positive temperature coefficient characteristics).
Heat dissipation structure: aluminum fins (thermal conductivity ≥ 200W/m·K) or ceramic substrate (high temperature resistance up to 600°C).
Surface treatment: anodized layer (corrosion resistance) or PTFE coating (acid and alkali resistance).
Dimensions:
Chip size: Φ5mm–Φ100mm (supports special-shaped customization).
Heat sink length: 50mm–1200mm, fin spacing 5mm–30mm.
Service life: 20,000–100,000 hours (based on operating temperature and heat dissipation conditions).
Customizable services: support power, voltage, Curie temperature adjustment, optional explosion-proof certification, IP protection level (such as IP68), integrated NTC sensor, etc.
Self-limiting temperature safety feature:
No external thermostat is required. When the temperature exceeds the Curie point, the resistance rises sharply, and the power is automatically reduced to a safe range to prevent overheating and burning.
High efficiency and energy saving:
Thermal efficiency is ≥95%, electrical energy is directly converted into thermal energy, and energy consumption is reduced by 30% compared with traditional resistance wire heaters.
Fast response and silent operation:
The heating speed is ≤30 seconds (to 200°C), no mechanical vibration noise, suitable for silent home appliances (such as air purifiers, medical equipment).
Long life and high reliability:
No risk of oxide wire burning, life is 2-3 times longer than that of resistance wire heaters, and it is resistant to frequent start and stop (>10,000 cycle tests).
Environmental adaptability:
Moisture-proof, dust-proof, and corrosion-resistant design (optional IP68/IP69K protection level), suitable for humid or harsh industrial environments.
Lightweight and compactness:
The aluminum heat sink has a low density (2.7g/cm³), and the volume is 50% smaller than that of traditional heaters, suitable for space-constrained scenarios.
Intelligent compatibility:
Supports PWM power regulation and IoT access (APP remote temperature control), suitable for smart home/Industry 4.0 systems.
Global Compliance:
CE, UL, CCC, RoHS certified
