PTC (Positive Temperature Coefficient) thermistors are temperature-sensitive electrical components whose resistivity undergoes an abrupt and often reversible change when the ambient temperature to which the device is exposed crosses a certain threshold. The B59010D1135B040 is a NTC (Negative Temperature Coefficient) thermistor which can be used for a variety of applications, such as detecting an ambient temperature increase or decrease, or delivering precise temperature measurement for a variety of monitoring requirements.

Application Field

The B59010D1135B040 NTC thermistor offers a broad range of uses, such as temperature measurement, temperature compensation, overheat protection, and precise temperature control. It was designed for wide temperature ranges, from -55 to +150°C, and is suitable for a multitude of general-purpose applications. This thermistor is appropriate for monitoring circuits of any size, for example, in AC and DC power supplies, or motor circuits.

Working Principle

NTC thermistors belong to the group of semiconductor-type temperature transducers. An NTC thermistor, such as the B59010D1135B040, essentially comprises a sandwich construction of a resistive element connected in series with a low-temperature-coefficient semiconductor. When the temperature outside the thermistor increases, the current passing through it is limited because of the semiconductor, thereby creating a negative temperature coefficient (NTC). An electrical circuit is then designed to sense this temperature rise.

In the B59010D1135B040, an exact calibrated resistance value is given at operating temperatures. Thus, an AC or DC power supply can be designed to read the temperature accurately. This temperature data can then be used to compensate temperature variations in the circuit, or to alert the user if temperatures become unsafe. In larger systems, multiple thermistors can be placed in series to ensure proper temperature control.

Conclusion

In conclusion, the B59010D1135B040 is a NTC thermistor designed for a broad range of applications from temperature measurement to precise temperature control. It is designed for wide temperature ranges from -55 to +150°C and is suitable for a multitude of general-purpose applications. It operates on a negative temperature coefficient (NTC) principle whereby the current passing through it is limited as the ambient temperature to which it is exposed increases, resulting in an exact calibrated resistance value at operating temperatures.
