IIsifudumezi sombane se-PTCyiisifudumezi sombanengokusekelwe kwizinto eziphathekayo ze-semiconductor, kunye nomgaqo wayo wokusebenza kukusebenzisa iimpawu ze-PTC (i-Positive Temperature Coefficient) izinto zokufudumeza.Izinto ze-PTC zizinto ezikhethekileyo ze-semiconductor ezixhathisa ukwanda kweqondo lobushushu, oko kukuthi, inophawu oluhle lomlinganiso wobushushu.
Xa iIsixhobo sokupholisa samandla ombane aphezulu se-PTCinamandla, ekubeni ukuchasana kwezinto ze-PTC kwanda ngeqondo lokushisa, ubushushu obukhulu buya kuveliswa xa ikhoyo ngoku idlula kwizinto ze-PTC, eziza kutshisa izinto ze-PTC kunye nokusingqongileyo.Xa iqondo lokushisa liphakama kwinqanaba elithile, ixabiso lokumelana nezinto ze-PTC landa ngokukhawuleza, ngaloo ndlela linciphisa ukuhamba kwangoku, ukunciphisa amandla okufudumala kunye nokufikelela kwisimo sokuzinza.
Izifudumezi zombane ze-PTC zineenzuzo zokuphendula ngokukhawuleza, ukufudumeza okufanayo, ukhuseleko kunye nokuthembeka, njl., kwaye zisetyenziswa ngokubanzi kwizixhobo zendlu, iimoto, unyango, umkhosi kunye nezinye iindawo.Ngelo xesha, ngenxa yokuba i-heater yombane ye-PTC inezakhiwo zokuzinza, nayo inethuba elihle lokufaka isicelo kulawulo lobushushu.
Kufuneka kuqatshelwe ukuba i-heater yombane ye-PTC kufuneka igweme ukugqithisa kunye nokusebenza kwexesha elide lobushushu obuphezulu ngexesha lokusetyenziswa ukuphepha umonakalo kwizinto ze-PTC.Ngelo xesha, xa ukhetha i-heater yombane ye-PTC, kufuneka ikhethwe kwaye isetyenziswe ngokweemfuno zangempela kunye nendawo yokusetyenziswa.
