| Core Principle | Positive Temperature Coefficient: Resistance increases as temperature rises. |
| Product Overview | A type of sensor characterized by a sharp change in resistance in response to temperature variations. It is primarily used for overheat protection, temperature switching, and self-regulating heating. |
| Typical Applications | ·Overheat protection in motors (e.g., fans, water pumps)
·Overcharge/overheat protection in batteries
·PTC heating elements (e.g., automotive seat heaters)
·Overcurrent protection in circuits (as self-resetting fuses) |
| Recommended Use | Ideal for applications requiring temperature switching, limit protection, or heating, such as:
·Safety protection in industrial equipment
·Safety circuits in appliances
·Thermostatic heaters |
| Key Advantages | ·Excellent switching characteristics
·High reliability and maintenance-free operation
·Integrates both sensing and switching functions |
