Purchasing New and Replacement Thermistors

Thermally sensitive resistors, also more commonly known as thermistors, are electrical resistance devices that change as ambient temperatures change. The first thermistors were created in the early 1830s, but it took roughly 100 years for the devices to become commercially viable. A lot of the electronic applications we use on a daily basis benefit from thermistors. In most cases, thermistors are used as temperature sensors, but in some instances, they function as current protection, current limiters, and also heating elements.

Considering that thermistors serve different applications, it is important to ensure that you are purchasing and using ones that are optimized for the application it is functioning within. If you are buying new or replacing existing devices, you should first ask yourself three questions. Taking the time to think will help your business get desired results.

  1. What is the base resistance of your application, or what is the base resistance of the thermistor already in use?
  2. What is the relationship/curve between resistance and temperature?
  3. What size and package style do you need for your application?

At Sensor, we can help your business identify the optimal thermistor to use in any application. For more information about thermistor accuracy, stability, size, and packaging styles, please give us a call today.
