B57504K103A3

NTC thermistors, often referred to as negative temperature coefficient thermistors, are temperature sensitive semiconductor devices with a resistance that decreases as temperature increases. They are composed of sintered semiconducting material, typically ceramic, with a metal oxide, which is commonly composed of a metal or metalloid.B57504K103A3 is one of the most common NTC thermistors on the market. It has an operating temperature range of -40°C to 150°C (-40°F to 302°F), resistance at 25°C of 10K Ohms ± 3%, thermal time constant typically of 5s (time required for the device to reach 63.2% of the difference between the old and new temperature at a constant environment temperature) and a maximum dissipation constant of 3000mW.

NTC thermistors can be used in a variety of applications because of their wide range of capability and temperature ranges. B57504K103A3 is primarily used in temperature sensing, power-limiting, and overheating protection. It can also be used in automotive, communications, HVAC, and other applications that require reliable temperature measurement and temperature regulation.

The temperature sensing capability of the B57504K103A3 is based on its ability to convert a temperature-dependent resistance change to a temperature-dependent output voltage. Generally, a voltage is applied across the two pins of the thermistor and the resistance is measured using an ohmmeter. From this reading, the temperature can then be calculated. This type of temperature sensing is known as positive temperature coefficient (PTC) sensing.

Another important application field of B57504K103A3 is power limiting and overheating protection. This type of application relies on the thermistor\'s ability to detect temperature changes and respond accordingly by opening or closing a circuit. When the temperature exceeds a certain threshold, the thermistor will open the circuit, limiting the flow of electricity and preventing the device from overheating. Conversely, when the temperature has cooled down, the thermistor will close the circuit, allowing the device to once again receive power.

Overall, the B57504K103A3 is a versatile thermistor that can be used in many applications. It is accurate and reliable enough for use in temperature measurement, but powerful enough to provide power limiting and overheating protection. This combination of features makes it an ideal solution for temperature monitoring and protection.
