  2. Temperature coefficient - Wikipedia

    en.wikipedia.org/wiki/Temperature_coefficient

    A positive temperature coefficient (PTC) refers to materials that experience an increase in electrical resistance when their temperature is raised. Materials which have useful engineering applications usually show a relatively rapid increase with temperature, i.e. a higher coefficient.

  3. Self-regulating heater - Wikipedia

    en.wikipedia.org/wiki/Self-regulating_heater

    A positive-temperature-coefficient heating element (PTC heating element), or self-regulating heater, is an electrical resistance heater whose resistance increases significantly with temperature. The name self-regulating heater comes from the tendency of such heating elements to maintain a constant temperature when supplied by a given voltage.

  4. Thermistor - Wikipedia

    en.wikipedia.org/wiki/Thermistor

    In crystal oscillators for temperature compensation, medical equipment temperature control, and industrial automation, silicon PTC thermistors display a nearly linear positive temperature coefficient (0.7%/°C). A linearization resistor can be added if further linearization is needed. [23]

  5. Ceramic heater - Wikipedia

    en.wikipedia.org/wiki/Ceramic_heater

    A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). [1] [2] [failed verification] Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters.

  6. Zener diode - Wikipedia

    en.wikipedia.org/wiki/Zener_diode

    The two types of diode are in fact constructed in a similar way and both effects are present in diodes of this type. In silicon diodes up to about 5.6 volts, the Zener effect is the predominant effect and shows a marked negative temperature coefficient. Above 5.6 volts, the avalanche effect dominates and exhibits a positive temperature ...

  7. Heating element - Wikipedia

    en.wikipedia.org/wiki/Heating_element

    Heating element performance is often quantified by characterizing the power density of the element. Power density is defined as the output power, P, from a heating element divided by the heated surface area, A, of the element. [5]

  9. Resettable fuse - Wikipedia

    en.wikipedia.org/wiki/Resettable_fuse

    A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits. The device is also known as a multifuse or polyfuse or polyswitch .
