ʻO nā dielectrics ʻili plastik i hoʻohana pinepine ʻia i ke kūkulu ʻana i nā capacitors ʻili metallized e komo pū me ka polypropylene (PP), polyphenylene sulfide (PPS), polyester, a me ka pepa metalized (MP). Loaʻa i kēia mau mea dielectric nā hiki ke ho'ōla pono'ī like ʻole.

Ke haki ka ʻāpana i loko o kahi capacitor kiʻiʻoniʻoni i hoʻoheheʻe ʻia, ʻo ka arcing ke kumu o ka papa metala lahilahi a puni ka wahi hewa e mahu. Hoʻopau kēia kaʻina hana mahu i ka papa metala alakaʻi ma ka wahi a puni ka hemahema. Ma muli o ka wehe ʻia ʻana o ka mea alakaʻi, ʻaʻole hiki ke hana i kahi kaapuni pōkole ma waena o nā papa. Pale kēia i ka hāʻule ʻana o ka ʻāpana.

ʻO ka hiki ke ho'ōla pono'ī o kahi capacitor kiʻiʻoniʻoni metallized e pili ana i nā kumu he nui e pili ana i nā waiwai o ka mea dielectric a me ka mānoanoa o ka papa metala. Pono ke kaʻina hana vaporization i ka lako kūpono o ka oxygen a me nā mea dielectric me ka nui o ka oxygen ʻili he mau waiwai ho'ōla pono'ī maikaʻi. ʻO kekahi o nā dielectrics kiʻiʻoniʻoni plastik i loaʻa nā ʻano ho'ōla pono'ī maikaʻi e like me ka polypropylene, polyester a me ka polycarbonate. Ma ka ʻaoʻao ʻē aʻe, ʻo nā dielectrics kiʻiʻoniʻoni plastik me ka haʻahaʻa o ka oxygen ʻili he mau ʻano ho'ōla pono'ī maikaʻi ʻole. ʻO Polyphenylene sulfide (PPS) kekahi o ia mau mea dielectric.

Ma waho aʻe o ka hoʻonui ʻana i ka hilinaʻi, ʻo ka hiki ke ho'ōla ponoʻī o nā capacitors kiʻiʻoniʻoni i hoʻoheheʻe ʻia e kōkua i ka hoʻomaikaʻi ʻana i ko lākou ola hana. Eia nō naʻe, ʻo ka ho'ōla ponoʻī ke kumu o ka hōʻemi ʻana o ka ʻāpana electrode i hoʻoheheʻe ʻia i ka hala ʻana o ka manawa.

I nā noi, ʻo kekahi o nā kūlana e hiki ai ke hoʻolalelale i ka hāʻule ʻana o kahi ʻāpana e komo pū me nā mahana kiʻekiʻe, nā voltages kiʻekiʻe, ka uila, ka haʻahaʻa kiʻekiʻe, a me ka hoʻopilikia electromagnetic (EMI).

Ma waho aʻe o nā waiwai ho'ōla pono'ī maikaʻi, loaʻa i nā capacitors kiʻiʻoniʻoni polyester metallized kahi dielectric constant kiʻekiʻe, ke kūpaʻa mahana maikaʻi, ka ikaika dielectric kiʻekiʻe, a me ka pono volumetric maikaʻi loa. ʻO kēia mau ʻano e hoʻolilo i kēia mau capacitors i mea kūpono no nā noi hana maʻamau. Hoʻohana nui ʻia nā capacitors polyester metallized no nā noi DC e like me ka pale ʻana, ka bypassing, ka decoupling, a me ka hoʻopau ʻana i ka walaʻau.

Hāʻawi nā capacitors polypropylene metallized i ke kū'ē'ē insulation kiʻekiʻe, ka omo dielectric haʻahaʻa, nā pohō dielectric haʻahaʻa, ka ikaika dielectric kiʻekiʻe, a me ke kūpaʻa lōʻihi. Hoʻohana nui ʻia kēia mau ʻāpana e hoʻohana pono ana i ka hakahaka i nā noi i hoʻopili ʻia e nā mains e like me nā kaapuni kānana, nā ballasts kukui, a me nā kaapuni snubber. Hiki i nā capacitors kiʻi polypropylene metala pālua ke kū i nā ukana voltage kiʻekiʻe a me nā ukana pulse kiʻekiʻe, a kūpono lākou no nā noi me ka likelika kiʻekiʻe o nā pulse kiʻekiʻe. Hoʻohana pinepine ʻia kēia mau capacitors i nā mea hoʻokele motika, nā snubbers, nā lako mana hoʻololi, a me nā monitor.
