This can offer some very interesting applications for example, PTC resettable fuses are related to PTC thermistors. Positive Temperature Coefficient (PTC) ThermistorsĪs the name suggests, positive temperature coefficient thermistors, or PTC for short, have resistance that will increase as their temperature goes up - the exact opposite of the NTC thermistors from the previous article in this series. Positive Temperature Coefficient (PTC) thermistorsĪbove is the PCB design you'll be reading about in the Altium 365 Viewer a free way to connect with your co-workers, clients, and friends with the ability to view the design or download with the single click of a button! Upload your design in a matter of seconds and have an interactive way to take an in-depth look without any bulky software or computer power.

Negative Temperature Coefficient (NTC) thermistors.

In this series, we’re going to be taking a look at a wide range of temperature sensors, talking about their advantages and disadvantages, and common implementations/topologies for their implementation. You can also look at PTC thermistors on Octopart if you want to see component stocks from distributors. You can find a full range of PTC thermistors, and many tens of thousands of other components and sensors in my Celestial Altium Library, the largest open source library for Altium Designer®. As always, these projects are open source, released under the MIT license allowing you to use them with very little in the way of restrictions. You can find those templates and the sensor implementations for the PTC thermistors covered in this article on GitHub. In the introduction to this series, we built a project template for the analog temperature sensor boards, and another for the digital boards.

In this installment of the series, we’re diving into Positive Temperature Coefficient (PTC) Thermistors. At the end of the series we’ll be building a pair of host boards for all the sensor cards we have developed which will allow us to test, compare and contrast the different sensor types over a full range of temperatures and conditions. If you want to add a temperature sensor to your project, this series has you covered with all the options covering the full range of precision and cost. This is part 3 of our project to test every type of temperature sensor with all the standard implementations/topologies.
