NTC-5D-15x is NTC Thermistor. An NTC (Negative Temperature Coefficient) thermistor is a type of temperature sensor that exhibits a decrease in electrical resistance as the temperature increases. The NTC thermistor is made from a semiconductor material with a negative temperature coefficient, meaning its resistance decreases with rising temperature.
The operation of an NTC thermistor is based on the principle that the movement of charge carriers (electrons) increases with temperature, leading to a decrease in resistance. This behavior makes NTC thermistors useful for temperature measurement and compensation in various electronic circuits and applications.
The SCK-2R55A is 2.5 Ohm, 5A, NTC Power Thermistor.
An NTC (Negative Temperature Coefficient) power thermistor is a type of thermistor that exhibits a decrease in resistance as the temperature increases. It is specifically designed to handle high power levels and is often used in applications where temperature sensing, control, or protection is required.
1. Negative Temperature Coefficient: The thermistor’s resistance decreases as the temperature rises. This negative temperature coefficient property allows it to be used for temperature sensing and control applications.
2. Power Handling Capability: NTC power thermistors are designed to handle relatively high power levels. They are constructed with materials and designs that can dissipate the heat generated during operation without experiencing performance degradation or damage.
3. Resistance-Temperature Curve: The resistance of an NTC power thermistor follows a specific resistance-temperature curve, which is provided by the manufacturer. This curve is used to calibrate and interpret the resistance values to determine the corresponding temperature.
4. Steep Temperature Sensitivity: NTC power thermistors exhibit a relatively steep change in resistance with temperature, providing accurate temperature measurements and sensing capabilities.
