PTC Heater

With the advent of technology, more emphasis is being laid on the safety features of the heaters. With Positive Temperature Coefficient (PTC) heaters, safety is prioritized. This technology keeps security at the forefront before other features so that people can release their worries regarding their safety as they can rely on these PTC Heaters.

In this article, we will look at various options and study the pros and cons of each of them to see which one is the best.

What is a PTC Heater?

Before jumping off to the PTC heating device, let us first study what Positive Temperature Coefficient means. If a material manifests a positive temperature coefficient, it means that as the temperature increases, its resistance to current raises proportionately. Initially, the current through these devices will observe a sharp rise with the low resistance but then decrease to zero when the desired temperature is reached.  

Positive Temperature Coefficient (PTC) heaters are self-regulating heaters that run with open-loop without any external diagnostic controls. While traditional fixed-resistance heaters use wires and coils to generate heat, PTC heaters use conductive inks printed on flexible, thin, polymer-based substrates.
