PTC qotishma simi o'rta qarshilik va yuqori musbat harorat qarshilik koeffitsientiga ega. Turli xil isitgichlarda keng qo'llaniladi. Haroratni avtomatik ravishda boshqarishi va doimiy oqimni ushlab turish va oqimni cheklash orqali quvvatni sozlashi mumkin. PTC qotishmasi avtomatik haroratni nazorat qilish, avtomatik quvvatni tartibga solish, doimiy oqim, oqim cheklash, energiya tejash va uzoq amaliy hayot kabi ko'plab afzalliklarga ega.
Biz ko'p turdagi PTC qarshilik simini ishlab chiqarishimiz mumkin. Ba'zi mijozlar PTC simlari o'rniga NiFe simlarini chaqirishadi.
