SMD IR Source for Your Portable Applications
These SMD infrared radiation sources are pulsable thermal emitters with a near black-body emittance. Their nanotechnology emitter surface achieves higher efficiency. This allows a lower element temperature of 600C, increasing lifetime. The SMD packaging makes them great for portable applications.
These SMD emitters are great for many projects where size and power are issues. The emitters are:
- More stable
- Less or no drift
- A lot more power
- A lot less noise (very important)
