Introduction

NTC thermistors are temperature sensors that are typically composed of sintered metal oxides, and are also often referred to as negative temperature coefficient (NTC) devices. They are widely used in a number of applications such as temperature sensing, current sensing, and voltage control. The MF11-0017005 is one such device that is designed for temperature sensing applications.

MF11-0017005 Application Field and Working Principle

The MF11-0017005 NTC thermistor is used mainly for temperature sensing in electronic thermal control and protection equipment. It is a ceramic chip thermistor with a high reliability, a good thermal response time, and a wide temperature range (-40~150℃). This makes the device suitable for a range of temperature sensing applications, such as home appliances, temperature control equipment, alarm systems, and so on.In terms of working principle, the MF11-0017005 NTC thermistor operates on the well-known negative temperature coefficient (NTC) phenomenon. This phenomenon states that the resistance of an NTC thermistor decreases with increasing temperature. This decrease is due to the fact that, at higher temperatures, an increased number of electrons become available as free carriers in the semiconductor material, thus leading to a decrease in the device’s resistance.

Temperature Sensitivity

The temperature sensitivity of the MF11-0017005 NTC thermistor is one of its main advantages, with a temperature coefficient (TC) value of -3.9 %/℃. This means that the resistance of the device reduces by 3.9 % for every degree Celsius increase in temperature. This makes the device highly sensitive to temperature variations, and ensures accurate temperature sensing and control.

Manufacturing Techniques

The MF11-0017005 NTC thermistor is manufactured using a special sintering process that involves mixing metal oxides into a paste, and then sintering the paste in a controlled cost furnace environment. The sintering process ensures a uniform and accurate distribution of the metal oxide particles in the thermistor material, which gives the device superior temperature sensitivity and thermal stability.

Shapes and Sizes

The MF11-0017005 NTC thermistor is available in a variety of shapes and sizes, and can be easily incorporated into a broad range of products and applications. For example, the device is available in the standard 2009, 2010, 2021, 2034, and 4566 packages. These packages range in size from 2 x 2 mm to 6.7 x 4.8 mm, and are also available in both standard and custom shapes to meet specific customer requirements.

Features and Benefits

In addition to its temperature sensitivity, the MF11-0017005 NTC thermistor also offers a number of features and benefits. These include a high reliability, a long service life, an accurate temperature coefficient, and excellent noise suppression. The device is also highly resistant to shock, vibration, and humidity, making it suitable for use in harsh industrial environments.

Conclusion

The MF11-0017005 NTC thermistor is a highly reliable and accurate temperature sensing device that is suitable for a range of temperature sensing and control applications. It operates on the well-known negative temperature coefficient (NTC) phenomenon, and features a temperature coefficient (TC) value of -3.9 %/℃. The device is available in a variety of shapes and sizes, and is also highly resistant to shock, vibration, and humidity.
