Thermal resistor wani nau’in resistor ne wanda ke canza juriyar juriyarsa domin amsa canjin yanayin zafi. Abu ne mai wuce gona da iri wanda aka saba amfani dashi a cikin da'irori na lantarki don samar da yanayin zafin jiki da sarrafawa. Juriya na thermal resistor yawanci ana ƙera shi don haɓaka tare da ƙara yawan zafin jiki, kuma adadin canjin juriya tare da zafin jiki an san shi azaman ƙimar juriya. Ana yawan amfani da thermal resistors a aikace-aikace kamar ma'aunin zafin jiki, sarrafa zafin jiki, da kuma kariyar yawan zafin jiki.
