Features: LPTC linear thermistor resistance increases with increasing temperature, a linear change, good linearity, and PTC polymer ceramic synthesis of thermistors, good linearity, without taking linear compensation measures to simplify the circuit design. ①, what is the temperature coefficient
Answer: The temperature coefficient refers to the high and low rate of change of the corresponding resistance of the linear thermistor with the rise and fall of temperature. For example, a thermistor with normal temperature (25 degrees) of 1K 300OPPM changes its resistance by 0.3 per degree of temperature change. when the temperature rises from 25 degrees to 105 degrees, the resistance changes from lK to lK X(l +0.3%X(l05-25))= 1.240K. The greater the temperature coefficient, the greater the resistance change rate. In addition to being determined by the temperature coefficient when the manufacturer produces the resistance change rate, the user can also increase the gain of the integrated amplifier and increase the change rate (PPM) during circuit design. Using ordinary resistors and thermistors in series and parallel can reduce the bottom change rate (PPM).
②. What is a positive temperature linear thermistor?
Answer: The general thermistor part has nonlinear changes in resistance and temperature, and it is necessary to design a linear compensation circuit. This product can maintain the linear change of resistance and temperature in the area of -40 degrees -250 degrees, thus simplifying the circuit. At present, the resistance temperature characteristics of the common PTC positive temperature thermistor are abrupt, and the linear region is very narrow. It is usually used for overcurrent protection of circuits, not for temperature detection and temperature compensation circuits. This product just complements the application field of this surface.
③, design, try out the product when there is any convenient place?
Answer: Thermistors with the same temperature coefficient can be connected in series and used in parallel, and their resistance-temperature characteristics remain unchanged. For example, lK 2OOOPPM can be connected in series into 2K 2O0OPPM or connected in parallel into 500Ω 20OOPPM, which provides convenience for circuit experiments and can obtain the best data, facilitate orders and mass production.
