Fast and High-Reliability PTC Thick-Film Ceramic Heaters Achieve RoHS Compliance

September 24, 2025

As industries increasingly demand energy-efficient, environmentally friendly, and high-performance heating solutions, MCH (Metal Ceramic Heater) thick-film PTC technology is emerging as the preferred choice. The Fast and High-Reliability PTC Thick-Film Ceramic Heater not only delivers rapid, even heating, but also complies with RoHS standards, ensuring eco-friendly operation across a wide range of applications.

With zero Pb, Cr+6, Hg, or Cd content, the MCH heater meets global environmental standards, offering manufacturers a compliant, green solution. Its design minimizes hazardous emissions while maintaining high reliability and consistent performance, making it ideal for consumer, industrial, and automotive applications.

Unlike traditional alloy wire heaters, the PTC thick-film ceramic heater generates heat directly through a resistance film layer, which is then distributed evenly via the ceramic board. Key benefits include:

• Consistent component temperature across the entire unit.
• High heat utilization rate for faster warm-up and energy efficiency.
• Self-limiting design prevents overheating and protects surrounding circuits.

The MCH heater is engineered to withstand demanding conditions with robust physical and electrical properties:

• Insulation resistance: R ≥ 5*10⁸Ω (500VDC)
• Compressive strength: up to 4000VAC (short-term)
• Rated operating temperature: 100–230℃, withstanding up to 500–700℃
• Volume density: ≥3.6 g/cm³
• Bending strength: ≥270 MPa
• Compression strength: ≥2700 MPa

These specifications ensure durability, reliability, and long service life, even in high-temperature or industrial environments.

The MCH PTC thick-film heater has broad utility, including:

• Personal care devices: Hair straighteners, curlers, and bidet seats.
• Household appliances: Electric water heaters, small heating equipment, and coffee machines.
• Automotive applications: Exhaust oxidation sensors and vehicle heating elements.
• Industrial equipment: Precision heaters for small machinery and control cabinets.

This versatility makes it a go-to solution for OEMs and ODM manufacturers looking to integrate high-efficiency heating cores into their products.
