Linear thermistor
As the name suggests, the linear thermistor's resistance changes linearly with temperature. It is made by physical technology and has excellent stability and complex linearity. It can be repeated millions of times without changing the characteristic curve. The resistance increases with temperature and changes in a straight line with good linearity. Compared with the NTC ceramic thermistor, the linearity is good and there is no need to take linear compensation measures to simplify the circuit design. Moreover, the resistance value has good consistency, strong interchangeability, and the appearance and specifications are accurate. The temperature sensing speed is fast, 1-2 seconds in air medium, and the sensitivity is high. With small size, solid structure and standardized appearance, it is suitable for automated installation of printed circuit boards.
①.What is temperature coefficient?
Answer: The temperature coefficient refers to the resistance change rate of the linear thermistor as the temperature rises or falls. Example: For a 1K 300OPPM thermistor at normal temperature (25 degrees), the resistance changes by 0.3% for every temperature change of 1 degree. When the temperature rises from 25 degrees to 105 degrees, the resistance changes from lK to lK X(l+(-0.3 %)X(l05-25))=0.760K. The larger the temperature coefficient, the larger the resistance change rate. In addition to the temperature coefficient determined by the manufacturer during production, the resistance change rate can also be increased by the user during circuit design by increasing the gain of the integrated amplifier and increasing the rate of change (PPM); by using ordinary resistors and thermistors in series or parallel, the resistance can be reduced. Rate of change (PPM).
②. What is a negative temperature linear thermistor?
Answer: Generally, the thermistor part has nonlinear changes in resistance and temperature, and a linear compensation circuit needs to be designed. This product can maintain linear changes in resistance and temperature within the range of -40 degrees to 250 degrees, thereby simplifying the circuit. At present, the temperature resistance characteristics of common NTC negative temperature thermistors are nonlinear, and the linear region is very narrow.
③. Are there any inconveniences when designing and trying out this product?
Answer: Thermistors with the same temperature coefficient can be used in series or parallel, and their temperature resistance characteristics remain unchanged. For example: lK 2OOOPPM can be connected in series to form 2K 2O0OPPM or in parallel to form 500Ω 20OOOPPM. It provides convenience for circuit experiments and can obtain the best results. Data to facilitate orders and mass production.

■Product features
CMZL chip linear PTC thermistor products are made of PTC materials and physical processes. They have excellent stability and complex linearity and can be repeated millions of times without changing the characteristic curve. The resistance increases as the temperature rises, changes in a straight line, and has good linearity. Compared with the thermistor synthesized by PTC polymer ceramic, the linearity is good, and there is no need to take linear compensation measures to simplify the circuit design. Moreover, the resistance value has good consistency, strong interchangeability, and the appearance and specifications are accurate. The temperature sensing speed is fast, 1-2 seconds in air medium, and the sensitivity is high. With small size, solid structure and standardized appearance, it is suitable for automated installation of printed circuit boards.
■Application scope
CMZL chip linear PTC thermistor is widely used in temperature control, temperature measurement and temperature compensation in communications, automobiles, instruments, computers, home appliances and other industries. The temperature resistance characteristics of the common PTC positive temperature thermistor are abrupt and the linear region is very narrow. They are usually used for overcurrent protection of circuits and are not used for temperature detection and temperature compensation circuits. This product just complements this application area.
