The Thermistor PTC 3K is a temperature-sensitive resistor with a resistance of 3,000 ohms at 25°C and a positive temperature coefficient of resistance. It is commonly used in electronic circuits for temperature sensing, overheat protection, and temperature compensation. The PTC 3K thermistor has an operating temperature range of -40°C to 150°C, a maximum power rating of 250mW, and a thermal time constant of 10 to 20 seconds.
Description
Thermistors are temperature-sensitive resistors that are commonly used in electronic circuits to monitor or control temperature. The PTC (Positive Temperature Coefficient) thermistor has a resistance that increases as the temperature increases, making it useful for temperature sensing and control.
The PTC thermistor 3K has a resistance of 3,000 ohms at 25°C (77°F) and a positive temperature coefficient of resistance. This means that as the temperature increases, the resistance of the thermistor also increases.
The PTC 3K thermistor is often used in electronic circuits as a temperature sensor, overheat protection, and temperature compensation. It is commonly found in applications such as automotive, consumer electronics, HVAC systems, and industrial equipment.
One advantage of PTC thermistors is that they do not require a power source for temperature sensing. They can be connected directly to a circuit, and changes in temperature will be reflected in the resistance of the thermistor. This makes them easy to use and cost-effective for temperature monitoring and control.
Here are the specifications of a typical Thermistor PTC 3K:
