PTC Heating Element - 5V 40°C
We have ✅ 1 available of the DF-FIT0844 in our Sydney warehouse. An extra 215 units available with a short lead time.
This PTC (Positive Temperature Coefficient) Heating Element is a self-regulating thermostatic ceramic heater that automatically maintains a constant surface temperature without external temperature controllers or sensors. Simply apply power and the element heats to its target temperature, then self-regulates to hold it steady.
The aluminium-tube encapsulation provides an insulated, constant-temperature surface with high heat transfer. It works on both AC and DC power regardless of polarity, making it versatile for a wide range of low-voltage heating applications.
Key Features
- Self-Regulating – Maintains constant temperature without external feedback circuitry
- AC or DC Operation – Polarity independent, works with either power type
- Aluminium Tube Encapsulation – Insulated surface with high heat transfer rate
- High-Temperature Silicone Wire – Durable leads rated for elevated temperatures
- Built-In PTC Chip – Designed for continuous, long-term operation
- Auto Power Adjustment – Draws more power when heat dissipation is higher, less as it reaches equilibrium
