    PTC is used in a wide range of industrial and commercial applications. PTC is one of the most common types of Thermistors used in industry today. They are a popular choice as they last longer, function better, and are incredibly accurate.

    RS offer an extensive selection of high-quality PTC from industry-leading brands including Carel, Electrotherm, Eliwell, EPCOS, Hanna Instruments.

    How does PTC work?

    PTC stands for "Positive Temperature Coefficient" which means that the resistance increases with rising temperatures. This effect can be used to protect circuits or devices against overcurrents. PTCs are effective for this cause as the overcurrent brings the PTC to a high temperature, thus a high resistance occurs which then limits the overcurrent. When the source for the overcurrent is removed, the PTC will cool down to function once again as a semiconductor. Applications for PTC include

    • Self-Regulating Heaters
    • Overcurrent Protection
    • Motor Starters
    • Liquid Level Sensors
    • Time Delay

    PTC Thermistors possess some key features including

    • Extremely long life
    • High efficiency
    • Low power requirements
    • Easy to install and maintain
    • Safe and convenient
