Negative Temperature Coefficient (NTC) thermistors are a type of temperature sensor whose resistance decreases as the temperature increases. This makes them ideal for a variety of applications, such as thermostats, motion detectors and power switch protection. The DC95G503VN is one such example.

The DC95G503VN is a radial leaded thermistor with a temperature range from -20°C (-4°F) to +85°C (185°F). It is designed with a 5% tolerance, produced from a high-quality metal oxide material, and features a resistance of 3.20K±5%Ω at 25°C.Its small size facilitates fast response times, and ensures it can be embedded easily in almost any object or environment.

This thermistor is often utilized in thermostats, where it is used to monitor, regulate, and maintain the ambient temperature. This is achieved by measuring the temperature, and then either switching on or off the heating or cooling elements, depending on which one is necessary to maintain or regulate a set temperature. Once the temperature has been achieved, the thermistor then switches off the heating or cooling elements and continues to monitor the temperature until a further adjustment is required.

In motion detectors, the DC95G503VN can be used as a temperature dialer that measures the intensity of the PIR (passive infrared) signals emitted by a moving object such as a person. The thermistor picks up the infrared radiation emitted by the object and converts it to a temperature value, which can then be used to trigger an alarm or switch on a light. This makes the thermistor ideal for rooms with movement sensitive installations.

In power switch protection, the DC95G503VN can be used to monitor the temperature of an electrical circuit or circuit board. If the temperature exceeds a certain level, the thermistor triggers the circuit breaker, shuttering off power to the device and preventing potential damage or hazard. This is usually combined with a voltage regulator to provide a comprehensive safety and thermal system.

As with all thermistors, the DC95G503VN is simple yet effective; it can be used in a variety of applications, particularly in thermostats, motion detectors, and power switch protection. Its small size and high accuracy make it well suited for such applications, while its extended range and fast response times ensure that it can handle any temperature fluctuations with ease.
