Mae gan wifren aloi PTC wrthsefyll canolig a chyfernod gwrthiant tymheredd positif uchel. Fe'i defnyddir yn helaeth mewn amryw o wresogyddion. Gall reoli tymheredd yn awtomatig ac addasu pŵer trwy gadw cerrynt cyson a chyfyngu ar gerrynt. Mae gan aloi PTC lawer o fanteision megis rheoli tymheredd awtomatig, rheoleiddio pŵer awtomatig, cerrynt cyson, cyfyngu cerrynt, arbed ynni a bywyd ymarferol hir.
Gallwn gynhyrchu sawl math o wifren gwrthiant PTC. Mae rhai cleientiaid yn galw gwifrau Nife yn lle gwifrau PTC.
