Description

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.

Description

The NTC-10D9 series NTC thermistor has to be connected in series to the power source circuit to avoid the surge current at the instant when the electronic circuits are turned on. The device can effectively suppress the surge current, and its resistance and power consumption can be greatly reduced after that through the continuous effect of the current so as not to affect the normal work current. Therefore the Power NTC thermistor is the most convenient and efficient instrument to curb the surge current and protect the electronic devices from being damaged.
