NTC thermistors are a type of temperature sensors used to measure temperature changes accurately. These devices work on the principle of resistance of temperature coefficient. In other words, when the surrounding temperature changes, the electrical resistance of NTC thermistors also changes in an inverse proportion. Such an inverse relationship between temperature and electrical resistance makes NTC thermistors ideal for a wide range of temperature measurements.

The PS302J2 is a popular NTC thermistor developed by Murata specifically for precision temperature sensing applications. It is a surface-mountable device made up of an advanced ceramic substrate and a special thermistor element. The PS302J2 is designed for temperature sensing in space-constrained environments such as servers, laptops, peripheral devices, set-top boxes, modems, and other electronics. It is ideal for use in consumer electronics, automotive, medical, and industrial applications.

The PS302J2 features a slim design and measures only 3.2x2.2mm in size and 0.3mm in height. It is made up of an epoxy coating over a platinum/cobalt (Pt/Co) core structure, with a steel & brass cover for protection. The device has a nominal resistance of 10 kΩ at 25°C and its resistance decreases with the increase of the surrounding temperature. It has a rated power of 0.5 mW, a temperature coefficient of -5 to -7 %/°K, and an operating temperature range of -40 to 105°C. Moreover, the PS302J2 is RoHS compliant and UL approved.

The PS302J2 is suitable for a broad range of temperature sensing applications. It can be used to detect temperature changes in small devices such as cellular phones, portable gaming devices, digital still and video cameras, and other digital media devices. It can also be used for precision temperature measurements for heating, ventilation, air-conditioning (HVAC) systems and industrial control systems. Additionally, the PS302J2 is used for medical monitoring applications such as body temperature measurement and infant incubator control.

To measure temperatures with the PS302J2, a circuit should be set up that includes a voltage source, the PS302J2 NTC thermistor, and an ammeter. When the device is exposed to a temperature change, its electrical resistance will change proportionally. When the resistance increases, the voltage and current in the circuit will decrease, and vice versa. This change in voltage and current is what is used to measure the temperature change. The device can be calibrated to accurately measure temperature changes with a high degree of precision.

In summary, the PS302J2 is a precision NTC thermistor designed to enable accurate temperature sensing in a variety of applications. It features a slim design with a tiny size and low height, and it is made of an advanced ceramic substrate and a special thermistor element. The PS302J2 is suitable for wide ranging applications, from consumer electronics, automotive, medical, to industrial applications. When set up in a circuit with an ammeter, the device can be used to measure temperature changes with high accuracy.
