Capacitor 104: Kuthetha ukuthini?

Amaxesha amaninzi, ukusuka wabaqalayo kunye nonomathotholo engahlawulwayo ngabantu kude zisuswe elektroniki, kodwa ngenxa yezizathu okanye omnye ujongene wokulungisa bezixhobo zombane, unako ukuva imibuzo efana nale: "Capacitor 104 - oko kuthetha ntoni? Indlela ukuqonda ixabiso capacitors zokuphawula? "Kweli nqaku, siza kuzama zecomputer ukubonisa lo mbuzo ethandwayo.

Ezo ukumakisha capacitors (104) ingaba kuphela kwiimveliso yodongwe. Oku kungenxa yokuba, ngokungafaniyo electrolysis, abasakwazi ezincinane imilinganiselo, yaye ngoko umzimba yabo nje akukho indawo irekhodi epheleleyo kunye eneenkcukacha yonke ingcaciso efanelekileyo, ezifana umthamo uhlobo lwemveliso le, njalo njalo.

Le capacitor yodongwe (104) yinxalenye ngokwendalo nayiphi wesekethe elektroniki. Ezi mveliso asetyenziswa naphi na apho kuyimfuneko ngayo ukusebenza iimpawu ukuba utshintshe wokwephuka zabo. capacitors yodongwe aneempawu rhoqo kakhulu, eziphantsi ukuvuza lwangoku, ilahleko ephantsi, ubungakanani amancinane kunye nendleko eziphantsi. Ngaloo izicelo apho ngentla-ochazwe efunekayo ngeempawu, le capacitors yodongwe kubalulekile, kodwa mvanje, iingxaki ezinxulumene ne inkqubo imveliso zabo, ezi zixhobo ezithathiweyo niche abanezixhobo amancinci amandla. Kutshanje, capacitors yodongwe kunye nomthamo 10 MF ezibonwe nezingaqhelekanga, iindleko iimveliso ezifana kuye ngokungeyomfuneko phezulu. Ukuphuhliswa kobugcisa namhlanje avunyelwe ukuba athandane iqela iifemu ukuba ukufikelela umthamo kwi 100 uF capacitors yodongwe Onokuyivakalisa ebaluleke nangakumbi impumelelo kungekudala. Ukongeza, amaxabiso onke amaqela ezi mveliso ziye yehla.

Ngoku nisinga kophawu capacitors yodongwe. Kuyinto kweentlobo ezimbini: amanani amathathu okanye amane. Thina ukumakisha "104", lo capacitor kunye nobhalo ibhekisela trehznakovoy encoding. Ingcaciso yale hlobo ilula: amanani amabini zokuqala ukumela capacitance e picofarads, kwaye yokugqibela - inani amaqanda. Makhe sijonge ukuba kuthetha ntoni ukuba capacitor "104". Kubonakala ukuba umvo zokuqala ezimbini (10) isikhongozeli kuthetha, kwaye le yokugqibela (4) - inani amaqanda. Ngenxa yoko, ukumakishwa kuthetha 104 100000 PF (100 nF okanye 0.1 uF). Njengoko ubona, yonke into ilula kakhulu. Loo uhlobo yokurekhoda nga encoder ixabiso ubuncinane 1.0 PF, oko kuya kuba le fomu ilandelayo: 010. Ukuba kuyimfuneko ukuba kurekhodwe ixabiso capacitance ngaphantsi kwe picofarad omnye ukusebenzisa oonobumba Latin R. Le ngxelo kuya kuba le fomu ilandelayo: 0R5, oko kukuthi 0.5 PF. Ukuba umthamo ngaphantsi kwe 1.0 PF, ngoko ke inani lokugqibela ibekwa 9, oko akuthethi ukuba kuyimfuneko ukuba isibuzi zero-9. Nanku umzekelo irekhodi enjalo - 109 (1.0 PF), 159 (1.5 PF), kunye 689 (6.8 PF).

Ngoku cinga chetyrehznakovuyu yokumakisha capacitors yodongwe. Ngenxa yoko, imivo zokuqala ezintathu urekhodisho kuthetha e picofarads capacitance, kwaye owesine - inani amaqanda.

Apha kufuneka ukuba wazi ukuba yintoni na capacitor "104". Ngoku, ukuba ufuna capacitors yodongwe, unako lula ukuqonda indlela ixabiso capacitance irekhodwa kwisisele ethile. Kwaye musa ukuba bafune uncedo lobungcali.
