Highly Sensitive Thermistor for Battery Pack and Power Supply Temperature Detection

Murata announced the highly accurate NXRT series of radial-leaded NTC thermistors. Utilizing Murata's highly accurate NCP15 series chip thermistor within an epoxy resin, the NXRT series is available with the nominal resistance values of 2 k, 10 k, 33 k, 47 k or 100 k ohm at 25 degrees C. Nominal resistance accuracy is typically in the range of +/- 1 % to 5 %. Measurement sensitivity is believed to bethe best available within the industry. At +50 degrees C the temperature detection sensitivity deviation is within +/- 0.6 degrees C, and is within +/- 1.4 degrees C at 100 degrees C.

The low cost NXRT series is ideal for accurate temperature detection in a wide range of consumer electronics and domestic electrical appliances. The thermistor is particularly suited to measuring the temperature of a power supply circuit or battery.

The thermistor package measures 4.0 x 2.0 x 40 mm in total including the 0.4 mm diameter radial leads. The NXRT series is suitable for use in most environments and has an operating temperature range from - 40 to + 125 degrees C.
