Not all resistors with the same resistance and current passing through are going to reach the same temperature as your comment indicates. No, you cant 'tune' the amount of power dissipated - but you can tune a resistor to more effectively radiate heat. Order today, ships today. I'm running a small PTC heater element off of 24vdc. The major difference in characteristics between a resistor and a heating element is that resistors are designed from a material standpoint to have a low thermal resistance change. When a current flows through a PTC the heat generated raises the temperature of the PTC. Positive temperature coefficient heating elements can be made of several materials. 4.2 (11) $1001 - $1280. In a heating element that uses a thermistor with a positive temperature coefficient (PTC), called a PTC heating element, the temperature increases rapidly. DIY Solar water heater. Really, you could use phase control to regulate it as well, just changing the phase delay to throttle. Anywhere a surface needs to be heated but has limited mounting space for generating heat. In contrast, a conventional heating element that produces the correct amount of heat at the desired temperature will produce the same amount of heat at low temperature, resulting in long warm-up times. The PTC resistor (also known as PTC thermistor) is an electronic component that changes its resistance as a function of temperature. The resistance of the heating element is about 1.6 at room temperature and increases when heated externally. SIM-CAL STUDIO contains useful simulation and calculation tools.
