Temperature Sensors - NTC Thermistors are sensors used to measure temperature. These sensors are typically small and use semiconductors made of resistive materials with a large temperature coefficient of resistance. The temperature coefficient of resistance (TCR) of the materials is often measured as a property of the semiconductor and is a positive or negative value that represents the change in resistance of the material for a one degree change in temperature.

The MM103G1K is a negative temperature coefficient (NTC) thermistor. It is a small, sealed component ideally suited to use at high temperatures. It is designed for applications in which the operating range is from -20 to +150 °C. In comparison to other thermistors, it requires only minimal wiring space, thereby making it suitable for use in compact products. As its size and cost are relatively low it is ideal for use in mass production.

The MM103G1K consists of a metal ceramic substrate, a metal resistor layer and a gold plated protective layer. The metal ceramic substrate is composed of a metal oxide mixed with organic material, and is a semi-conductor that changes its resistance in relation to temperature. The metal resistor layer, when heated or cooled, can increase or decrease its resistance, generating a voltage change. The protective gold plated layer is an anti-corrosion coating designed to guard against oxidization due to humidity or temperature.

The working principle of the MM103G1K is based on the NTC thermistor. It works by measuring the change in resistance of a substrate as the temperature changes. As the temperature increases, the resistance of the substrate decreases. The level of resistance decreases with a negative temperature coefficient. The amount of change in resistance is directly proportional to the amount of temperature change.

The MM103G1K can be used in a variety of applications. It is commonly used in the automotive industry due to the ability to quickly and accurately detect engine temperatures. It can also be used in home appliances and commercial cooling and air conditioning systems to ensure that temperatures remain within a safe range. It can also be used in an industrial setting for monitoring the temperature of various systems and machines. In aerospace industry, the MM103G1K can be used for measuring the temperatures of jet engines, avionics and engines operating in extreme conditions.

The MM103G1K is a reliable and cost-effective thermistor solution that can be used in a variety of applications. Its small size, low cost, high accuracy, and wide temperature range make it an ideal choice for temperature sensing applications. It is highly resistant to thermal shock, making it suitable for measurement in high temperature and thermal shock environments. The protection layer helps to ensure its life and reliability. It is designed to be used in various temperature sensing applications, providing a reliable measurement solution.
