NTC thermistors (Negative Temperature Co-efficient) are thermally-sensitive resistors whose resistance decreases with increasing temperature. The DC95F202VN is a tailored NTC thermistor device, utilising high precision thin-film technology – a furnace-sintered NTC chip is combined with an advanced interface circuit to form a complete temperature sensing and conditioning device.

A DC95F202VN consists of an NTC thermistor, a protective circuit, and a leadframe. The NTC thermistor is a disc-shaped ceramic body composed of sintered metal oxides and heat-sensitive resistive layers. Its resistance decreases, and its temperature coefficient increases with increasing temperature. The protective circuit prevents overvoltage and overcurrent conditions and is coupled to the NTC thermistor through precision terminations. The leadframe provides the electrical connection between the NTC thermistor and the housing.

The DC95F202VN application field covers a wide range of temperature measurement/control applications, including communications and computer equipment, industrial automation, heating and air conditioning, automotive air conditioning, refrigeration, temperature monitoring, cooling units, and other temperature-sensitive control systems. Furthermore, it is suitable for use in extreme environments due to its high resistance to mechanical shock and vibration.

In terms of working principle, DC95F202VN functions by sensing and monitoring the temperature around it and providing a conversion of the temperature measurement. The NTC thermistor element has a high sensitivity to temperature, and is highly stable, with low power consumption and fast response time. The resistance of the thermistor changes with the temperature, and the precise resistance level determines the measurement of the temperature. The DC95F202VN’s protective circuit prevents the NTC thermistor from being damaged due to excessive overvoltage and overcurrent conditions.

The DC95F202VN has a small size and light weight, allowing for easy installation of the device, making it suitable for many applications. Furthermore, any modification of the original structure can be made to meet the specific requirements of the user, such as making adjustments to operating voltage, temperature ranges, and the thermistor’s type. All these features make the DC95F202VN an ideal choice for sensing and monitoring temperature in a wide range of applications.
