Product Description
The LPTC-4050H and LPTC-4000H thermistors are high-precision PTC linear thermistors with a maximum temperature measurement of 125°C. Their resistance increases linearly with increasing temperature, demonstrating excellent linearity. Compared to PTC polymer ceramic thermistors, these thermistors offer superior linearity, eliminating the need for linear compensation measures and simplifying circuit design.
