Izihlungi ze-LC low-pass zidlala indima ebalulekile ekucubunguleni isignali ye-elekthronikhi. Bangakwazi ukuhlunga ngempumelelo amasignali emvamisa ephansi futhi bacindezele umsindo wefrikhwensi ephezulu, ngaleyo ndlela bathuthukise ikhwalithi yamasignali. Isebenzisa i-synergy phakathi kwe-inductance (L) kanye ne-capacitance (C). I-inductance isetshenziselwa ukuvimbela ukudlula kwezimpawu ze-high-frequency, kuyilapho i-capacitance idlulisela futhi ikhulisa amasignali aphansi. Lo mklamo wenza izihlungi ze-LC ezine-low-pass zidlale indima ebalulekile ezinhlelweni eziningi ze-elekthronikhi, ikakhulukazi ekuthuthukiseni ikhwalithi yesignali nokunciphisa umsindo.
Ngokuthuthuka kwesayensi nobuchwepheshe, siyakhula isidingo samasignali ekhwalithi ephezulu emikhakheni efana nokuxhumana okungenantambo, ukucutshungulwa komsindo, nokudluliswa kwezithombe. Njengengxenye ebalulekile yokucubungula isignali, izihlungi ze-LC ezinephasi eliphansi zinamathuba abanzi okusebenza kule mikhakha. Ezinhlelweni zokuxhumana ezingenazintambo, izihlungi ze-LC low-pass zingakwazi ukuhlunga ngokuphumelelayo amasignali okuphazamisa ama-high-frequency futhi zithuthukise ikhwalithi yesignali ekugcineni kokwamukela; ekugcineni kokudlulisa, kungaqinisekisa futhi ukuthotshelwa komkhawulokudonsa wesiginali futhi kugweme ukuphazamiseka namanye amabhendi amafrikhwensi. Emkhakheni wokucubungula umsindo, izihlungi ze-LC low-pass zisiza ukususa umsindo we-high-frequency kanye namasignali alahlekile kumasignali omsindo, anikeze imiphumela yomsindo ecacile nemsulwa. Ikakhulukazi ezinhlelweni zomsindo, izihlungi zibalulekile ekuthuthukiseni ikhwalithi yomsindo. Mayelana nokucubungula isithombe, isihlungi se-LC low-pass sinciphisa umsindo we-high-frequency esithombeni, sicindezela ukuhlanekezela kombala, futhi siqinisekisa ukuthi isithombe sicacile futhi singokoqobo.
Izici eziyinhloko zesihlungi se-LC low-pass zifaka impendulo yefrikhwensi ebushelelezi kanye nomugqa omuhle wesigaba. Ngaphansi kwe-cutoff frequency, ukuncishiswa kwesignali kuncane, kuqinisekisa ubuqotho besignali; ngaphezu kwefrikhwensi yokusika, ukuncishiswa kwesignali kungumqansa, kuhlunga ngokuphumelelayo umsindo we-high-frequency. Ngaphezu kwalokho, umugqa wayo wesigaba uqinisekisa ukuthi isignali ingagcina ubudlelwano bayo besigaba sangempela ngemva kokuhlunga, okubaluleke kakhulu ezinhlelweni zokusebenza ezifana nokucutshungulwa komsindo nokudluliswa kwesithombe.
Ngokuthuthuka kobuchwepheshe, isihlungi se-LC low-pass sizoqhubeka nokusungula futhi sithuthuke ekuqondeni kwe-miniaturization, ukuhlanganiswa, kanye nezinhlelo zokusebenza zamafrikhwensi aphezulu, siqhubeke sandise izindawo zaso zokusebenza. Ngokuzayo, izihlungi ze-LC ezinephasi eliphansi zizodlala indima enkulu ezinhlelweni zikagesi eziningi, zikhuthaze ukuthuthukiswa kwesayensi nezobuchwepheshe kanye nenqubekelaphambili yemboni.
