IyoPTC hita yemagetsiihita yemagetsiyakavakirwa pazvinhu zve semiconductor, uye musimboti wayo wekushanda ndeyekushandisa hunhu hwezvinhu zvePTC (Positive Temperature Coefficient) pakudziyisa. Zvinhu zvePTC chinhu chakakosha che semiconductor chine resistance inowedzera nekupisa, kureva kuti, chine hunhu hwe positive temperature coefficient.
KanaPTC high voltage coolant heaterinosimbiswa, sezvo kuramba kwechinhu chePTC kuchikwira nekupisa, kupisa kwakawanda kunogadzirwa kana simba remagetsi richipfuura nepakati pechinhu chePTC, icho chinozopisa chinhu chePTC nenzvimbo yakapoteredza. Kana tembiricha yakwira kusvika padanho rakati, kukosha kwekudzivirira kwechinhu chePTC kunowedzera zvakanyanya, nokudaro zvichideredza kufamba kwesimba remagetsi, zvichideredza simba rekupisa uye kusvika pakuzvigadzirisa.
Mahita emagetsi ePTC ane zvakanakira zvekupindura nekukurumidza, kupisa kwakafanana, kuchengetedzeka uye kuvimbika, nezvimwewo, uye anoshandiswa zvakanyanya mumidziyo yemumba, mota, kurapwa, zvemauto nedzimwe nzvimbo. Panguva imwe chete, nekuti hita yemagetsi yePTC ine hunhu hwekuzvigadzirisa, ine mukana wakanaka wekushandisa mukudzora tembiricha.
Zvinofanira kucherechedzwa kuti hita yemagetsi yePTC inofanira kudzivirira kuwandisa zvakanyanya uye kushanda kwenguva refu panguva yekushandiswa kudzivirira kukuvara kwezvinhu zvePTC. Panguva imwe chete, pakusarudza hita yemagetsi yePTC, inofanira kusarudzwa uye kushandiswa zvichienderana nezvinodiwa chaizvo uye nzvimbo yekushandisa.
