The Rapid Development of NTC Chip Thermistor
Oct 16, 2024NTC thermistor is a kind of ceramic semiconductor heat-sensitive crystal sintered by manganese, cobalt and nickel-based various metal oxides as raw materials. It is extremely sensitive to temperature changes. The temperature rises and decreases, and the resistance value decreases exponentially with the increase of temperature, and the temperature coefficient is as high as (3-6%/℃), and a small temperature change will cause a large change in the resistance value.
With the development of mobile communication technology and the trend of digitalization, the requirements for miniaturization, light weight, thinning, digitalization, multi-functionalization and production process automation of electronic equipment, the development and production of electronic components must also be miniaturized and chip-based. The rapid development of thinning and thinning. The trend of chip-based electronic components has also extended to the field of sensors, and chip-type thermistors are sensitive components that have undergone tremendous development in response to this trend.
NTC chip thermistors are divided into chip NTC thermistor products and chip NTC thermistor products. Chip NTC thermistor products are used for patch installation on circuit boards. Performance development, this development speed has far exceeded the traditional discrete thermistor. Let's talk about the characteristics of NTC thermistor series products.
Their characteristics are:
1) Small size, no leads, excellent soldering performance, suitable for high-density surface mount;
2) The surface of the porcelain body is encapsulated by glass, which has good moisture resistance, high reliability and stability;
3) Wide working temperature range: -40℃~+125℃, with excellent solderability and thermal shock resistance;
4) High-precision resistance value and B value constant;
5) Suitable for wave soldering and reflow soldering;
NTC chip thermistors have a wide range of applications and can be widely used in displays and general-purpose electronic circuits, such as:
1) Temperature measurement: electronic thermometer, electronic perpetual calendar, electronic clock temperature display, electronic gifts, etc.;
2) Temperature control: temperature sensing of rechargeable batteries of mobile phones, car phones, laptops, smart wearable devices, etc.;
3) Temperature compensation: in various circuits that require temperature compensation, such as semiconductor integrated circuits, liquid crystal displays, transistors, ICs, and crystal oscillators of mobile communication equipment.
4) Installed in the axial flow electrode, such as the micro motor in the computer, the focus motor of the camera lens and other equipment to control the motor speed;
5) Control the temperature of the print head during printing to prevent overheating; in the servo controller of the floppy disk and the driver of the pocket player, prevent data misreading and so on.
For all applications in this area, NTC chip thermistors are mounted on printed circuit boards. While electronic circuits are developing towards high-density assembly, chip NTC thermistors are rapidly developing new application fields in various military, industrial and civilian electronic equipment.
