Product Description

Axial Leaded Silicon PTC Thermistor Temperature Sensor KTY83-122 150 151 LPTC83-152
Features Of The PTC Thermistor Temperature Sensor
The resistance of the LPTC linear thermistor increases with the increase of temperature, and it changes in a straight line, with good linearity. Compared with the thermistor synthesized by PTC polymer ceramics, the linearity is good, and there is no need to take 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 resistance of the linear thermistor as the temperature rises and falls. Example: A thermistor of 1K 300OPPM at room temperature (25 degrees), the resistance value changes by 0.3% every time the temperature changes by 1 degree. When the temperature rises from 25 degrees to 105 degrees, the resistance value changes from lK to lK X (l+0.3% X(l05-25))=1.240K. The larger the temperature coefficient, the larger the resistance change rate. The resistance change rate is determined by the temperature coefficient in addition to the manufacturer's production. The user can also increase the gain of the integrated amplifier and increase the rate of change (PPM) when designing the circuit; using ordinary resistors and thermistors in series or parallel can reduce the bottom line. Rate of change (PPM).
②. What is a positive 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 the linear change of resistance and temperature in the range of -40 degrees to 250 degrees, thereby simplifying the circuit. At present, the resistance temperature characteristic of the common PTC positive temperature thermistor is abrupt, and the linear region is very narrow. This product just complements this wide range of applications.
③. What other conveniences are there when designing and trying this product?
Answer: The thermistors with the same temperature coefficient can be used in series or in parallel, and their resistance-temperature characteristics remain unchanged. For example: lK 2000PPM can be connected in series to 2K 2000PPM or in parallel to form 500Ω 2000PPM. Data, easy to order, mass production.
