Use MathJax to format equations. Copyright(c) 2022 TDK Corporation. If the element was made thick or irregular in shape, then there would be more than one path for the electrical current. One difference that does exist, though, is that heating elements are generally made of materials that will work at higher temperatures. A very good way to limit the inrush current is to use an inrush current limiter (ICL), in which a PTC thermistor and a thyristor (or relay) are used in combination with each other. PTC Resistor: Properties & Application - Heater 2023 In this case, the overcurrent brings the PTC to a high temperature and the resulting high resistance then limits the overcurrent. You can narrow your product search by setting parameters based on the product's characteristics. Use MathJax to format equations. The primary difference from a surface heater is that the ceramic heating element is bounded inside a protective cylinder or similar configuration.

Report a problem or incorrect product information. Some heating elements (PTC) wouldn't be used as a current limiting resistor because of the high temperature coefficient. Once a certain temperature (Curie temperature) is exceeded, the resistance of a PTC rises significantly. It's normal to run heaters in "burst" mode whereby you turn the heater on for several seconds/minutes, then turn it off for several seconds/minutes. This temperature is called the Curie temperature, because the material's magnetic properties also change markedly. However, many applications require control of two temperatures.
