Murata has announced ultra-tight tolerance versions of its NTC (negative temperature coefficient) thermistor series, the NCP series.

The ±0.5% tolerance versions are now available with consumer, industrial and automotive temperature ranges.

According to Murata, these ±0.5% tolerance chip NTC thermistors are the first of their kind to be developed and offer a low-cost alternative to IC-based sensing solutions when high sensing accuracy is required.

The parts are aimed at applications where the most accurate temperature sensing is required, such as air conditioning systems, power supply cooling/thermal management systems and automotive temperature sensing applications.

Ultra-tight tolerance thermistors are particularly important, say the company, in situations where the thermistors are to be used near the maximum operating temperature, since low accuracy could mean the maximum operating temperature of the system is exceeded.

Simulation software which calculates the output characteristics of any of 418 of Murata's NCP series of thermistors is available online, to help designers find the right part without any trial and error.
