04M4702JF

NTC Thermistors are temperature sensors with Negative Temperature Coefficients, and the 04M4702JF is a thermistor with a compact and thin design that is suitable for many temperature sensing applications. This thermistor is capable of providing reliable and accurate readings in a wide range of temperature measuring environments.

Components and Characteristics

The 04M4702JF consists of three components: a positive temperature coefficient (PTC) resistor, a negative temperature coefficient (NTC) resistor and a current limiting resistor. The PTC and NTC components act as temperature sensing elements in the circuit, while the current limiting resistor provides protection for the other elements in the circuit. The thermistor is also designed with a low thermal resistance to ensure accuracy and optimum performance. Additionally, the 04M4702JF has a wide temperature range of -40 to 125 degrees Celsius.

Working Principle

The working principle of the 04M4702JF is based on the variation of electrical resistance with temperature. PTC and NTC resistors both exhibit different changes in electrical resistance in response to changes in temperature. The PTC resistor increases the electrical resistance when the ambient temperature increases, while the NTC resistor decreases the electrical resistance when the ambient temperature increases.

When the ambient temperature increases, the NTC resistor decreases its electrical resistance, making it easier for electricity to flow. This increases the current flow through the NTC resistor, and thus increases the temperature of the thermistor. On the other hand, when the ambient temperature decreases, the NTC resistor increases its electrical resistance, thus decreasing the current flow through the NTC resistor and resulting in a decrease in the temperature of the thermistor.

Application Field

The 04M4702JF thermistor is suitable for many temperature sensing applications. It can be used in thermostats, temperature controllers and temperature switches. It is also typically used in home appliances such as air conditioners, refrigerators, and electric ovens. In addition, it is often used in industrial processes to monitor and control the temperature of liquids, such as oil and water.

The 04M4702JF thermistor is also used in medical applications, such as for taking temperatures of patients or monitoring body temperatures. Furthermore, it is widely used in automotive applications, such as in temperature sensors for engines and air conditioning systems.

Advantages

The 04M4702JF thermistor provides a number of advantages over other temperature sensors. One of the major advantages of this thermistor is its high accuracy and reliable readings. Additionally, the thermistor is capable of measuring temperatures over a wide range of values. Furthermore, it is lightweight and small, and has a low thermal resistance, which makes it useful for tight spaces such as cramped engine compartments and interior air conditioning systems.

The 04M4702JF thermistor is also cost-effective, and is capable of providing consistent and repeatable results. Lastly, it is easy to install and maintain, making it an ideal choice for those who need to measure temperatures quickly and accurately.
