Introduction to NTC Thermistors

NTC thermistors are temperature sensors that rely on the temperature-dependent resistance of a special semiconductor material. NTC thermistors are used in various temperature-sensing applications and are popular as they are small in size, inexpensive and have a fast response time to temperature changes.

B57560G145F Application Field and Working Principle

The B57560G145F is a negative temperature coefficient (NTC) thermistor, manufactured by Siemens. It is designed to accurately measure temperatures ranging from -50 degrees Celsius to +300 degrees Celsius, with a tolerance of ±1⁰C and 0.5 Celsius accuracy. It is frequently used as a temperature sensor or to protect against over-heating.The working principle of the B57560G145F is a property known as the PTC, or Positive Temperature Coefficient. A PTC is essentially an electrical resistor which changes its resistance with temperature. The B57560G145F is designed to have a negative temperature coefficient, or NTC. In other words, as the temperature increases, the resistance of the B57560G145F decreases. This makes it an ideal choice for temperature sensing applications, where precise temperature measurement is required.The B57560G145F is available in a wide range of package types, including TO-220, TO-92 and Gull Wing packages, making it suitable for use in a wide variety of applications.In addition to being used as a temperature sensor, the B57560G145F can also be used as an overload protection device. When the temperature exceeds a certain predetermined level, the resistance of the B57560G145F decreases, triggering an electrical signal that can be used to cut off power to the device in use.

Conclusion

The B57560G145F is a negative temperature coefficient (NTC) thermistor designed by Siemens. It is available in a range of package types, making it suitable for various temperature sensing applications, and can also be used as an overload protection device. It has a range of -50 degrees Celsius to +300 degrees Celsius with ±1⁰C tolerance and accuracy of 0.5 Celsius, making it an ideal choice for high accuracy temperature measurements.
