Na sekit DC, capacitor yiri sekit mepere emepe. Capacitor bụ ụdị ihe nwere ike ịchekwa chaja eletrik, ọ bụkwa otu n'ime ihe a na-ejikarị eme ihe.ihe eletrọniki. Nke a na-amalite site na nhazi nke capacitor. Ihe ndị kacha mfe nwere efere polar na nsọtụ abụọ na ihe mkpuchi dielectric (gụnyere ikuku) n'etiti. Mgbe a na-enye ike, a na-ana chajị efere, na-emepụta voltaji (ihe nwere ike ịdị iche), mana n'ihi ihe mkpuchi dị n'etiti, capacitor dum anaghị eduzi ya. Agbanyeghị, ikpe a dị n'okpuru ọnọdụ na voltaji dị mkpa (voltaji mmebi) nke capacitor agaghị agafe. Dịka anyị maara, ihe ọ bụla na-adị ka ihe mkpuchi. Mgbe voltaji gafere ihe na-abawanye ruo n'ókè ụfọdụ, ihe niile nwere ike iduzi ọkụ eletrik, nke a na-akpọ voltaji mmebi. Capacitors abụghị ihe dị iche. Mgbe capacitors gbajiri, ha abụghị ihe mkpuchi.

●Ihe dị iche:A na-akpọ capacitors eji eme ihe na sekit differential capacitors. Iji nweta akara mkpali spike na sekit flip-flop, a na-eji sekit capacitor differential iji nweta akara mkpali spike site na mgbaàmà dị iche iche (karịsịa rektangulu pulse).

●Ụgwọ ọrụ:A na-akpọ capacitor eji eme ihe na sekit nkwụghachi ụgwọ capacitor. Na sekit nkwụghachi bass nke onye na-ejide kaadị, a na-eji sekit nkwụnye mgbapụta obere ugboro a eme ka mgbaàmà obere ugboro dị na mgbaàmà ọkpụkpọ egwu dịkwuo mma. Na mgbakwunye, enwere sekit nkwụnye mgbapụta ugboro ugboro dị elu.

●Akpụkpọ ụkwụ:A na-akpọ capacitor eji na sekit bootstrap capacitor bootstrap, nke a na-ejikarị eme ihe na sekit mmepụta nke amplifier ike OTL iji mee ka ogo ọkara okirikiri dị mma nke mgbaàmà ahụ dịkwuo mma site na nzaghachi dị mma.

●Nkewa ugboro ole:A na-akpọ capacitor dị na sekit nkewa ugboro ugboro capacitor. N'ime sekit nkewa ugboro ugboro nke igbe ụda, a na-eji sekit capacitor nkewa ugboro ugboro eme ka igwe okwu dị elu rụọ ọrụ na band ugboro ugboro dị elu, igwe okwu dị n'etiti ugboro ugboro na-arụ ọrụ na band ugboro ugboro dị n'etiti na igwe okwu dị ala na band ugboro ugboro dị ala.

●Ike ibu:na-ezo aka na ikike mpụga dị irè nke na-ekpebi ugboro resonant nke ibu yana quartz kristal resonator. Ụkpụrụ ọkọlọtọ a na-ahụkarị maka capacitors ibu bụ 16pF, 20pF, 30pF, 50pF, na 100pF. Enwere ike ịgbanwe ikike ibu dịka ọnọdụ akọwapụtara si dị, a pụkwara ịgbanwe ugboro ọrụ nke resonator ka ọ bụrụ uru aha site na ịgbanwe ya.

Ugbu a, ụlọ ọrụ ihe nkiri na-etinye ihe nkiri na-abanye n'oge mmepe kwụsiri ike site na
