## Product Category 1: PTC Heaters

### What is a PTC Heater?

A PTC (Positive Temperature Coefficient) heater is a self-regulating electric heater made from polycrystalline barium titanate (BaTiO₃) ceramics doped with rare earth elements. As temperature rises, electrical resistance increases significantly, reducing current flow and preventing thermal runaway — no external thermostat required.

**Core Specifications:**
- Curie Temperature: 60°C–250°C (customizable)
- Voltage: 3V–999V (AC/DC)
- Service Life: 10+ years or 200,000+ switching cycles
- Response Time: Near-instantaneous

**Advantages over traditional heaters:**
1. Inherent safety — prevents thermal runaway
2. Energy-efficient — scales power to ambient temperature
3. Exceptional durability — no oxidizing filaments
4. Rapid thermal response
5. Wide voltage compatibility
6. Superior insulation in humid/underwater environments
