Capacitor 104: Kusho ukuthini?

Isikhathi esining impela, kusukela Wabasaqalayo amateur radio abantu zikude electronics, kodwa, ngezizathu ezithile bebhekene ukulungisa amadivaysi e-elekthronikhi, kungenzeka ukuzwa imibuzo enjengokuthi: "capacitor 104 - kusho ukuthini? Kanjani ukuqonda ukubaluleka kwalesi capacitors kophawu? "Kulesi sihloko, sizozama ukuhlwaya lo mbuzo ethandwa.

Okunjalo nekukumakwa capacitors (104) kuphela emikhiqizweni sobumba. Lokhu kungenxa yokuthi, ngokungafani electrolysis, ngezindawo anabantu abambalwa kakhulu Ubukhulu, ngakho-ke umzimba wabo nhlobo indawo irekhodi ephelele futhi egcwele lonke ulwazi olufanele, ezifana amandla umkhiqizo, uhlobo nokunye.

I capacitor Ceramic (104) iyingxenye engokwemvelo iyiphi wesifunda electronic. Le mikhiqizo asetshenziswa nomaphi kubalulekile ukusebenza amasignali ukuthi ukushintsha polarity yabo. capacitors bobumba babe kakhulu imvamisa izici, ongaphakeme ukuvuza zamanje, ukulahlekelwa ongaphakeme, usayizi amancane eziphansi. Kulezo izicelo lapho ngenhla echazwe edingekayo izici, le capacitors Ceramic nalolo, kodwa kuze kube muva nje, lapho umuntu enezinkinga ezihambisana inqubo ukukhiqizwa yabo, lezi amadivaysi kuthathwe niche namadivayisi encane umthamo. Muva nje, capacitors Ceramic ephethe namandla 10 MF waqonda njengoba ezingavamile, izindleko imikhiqizo enjalo ibilokhu ngokungadingekile okusezingeni eliphezulu. Ukuthuthukiswa zobuchwepheshe zanamuhla kwenze bavunyelwe kube inombolo amafemu ukufinyelela nomthamo 100 UF capacitors Ceramic futhi ukumemezela impumelelo okuseduze okubaluleke nakakhulu. Ngaphezu kwalokho, amanani kuzo zonke amaqembu mikhiqizo ziye kuncipha.

Manje phenya kophawu of capacitors sobumba. Kuyinto ezinhlobo ezimbili: kwamadijithi ezintathu noma ezine. Thina eziwuphawu '104 ", le capacitor ne notation libhekisela trehznakovoy wekhodi. Incazelo lolu hlobo ulula: amadijithi ezimbili zokuqala amelela capacitance e picofarads, kanti owokugcina uyoba ngo - inani amaqanda. Ake sibheke ukuthi kusho ukuthini le capacitor "104". It kuvela ukuthi owokuqala Izinombolo ezimbili (10) esitsheni izindlela, kanti isixuku esikhulu (4) - inani amaqanda. Ngakho, wokugubha kusho 104 100000 PF (100 NF noma 0.1 UF). Njengoba ubona, konke silula. ifomu okunjalo zokuqopha kungaba encode value ubuncane 1.0 PF, ke kuyodingeka ifomu elilandelayo: 010. Uma kubalulekile ukuqopha ukubaluleka capacitance engaphansi picofarad usebenzise izinhlamvu Latin R. Leli rekhodi kuyodingeka ifomu elilandelayo: 0R5, okungukuthi 0.5 PF. Uma umthamo esingaphansi 1.0 PF ke idijithi yokugcina ibekwe 9, akusho ukuthi kubalulekile ukuba engeza amaqanda 9. Nasi isibonelo yerekhodi ezinjalo - 109 (1.0 PF), 159 (1.5 PF), kanye 689 (6.8 PF).

Manje cabanga chetyrehznakovuyu wokugubha capacitors sobumba. Ngenxa yalokho, amadijithi amathathu wokuqala ukuqopha kusho e picofarads capacitance, kanti owesine - inani amaqanda.

Lapha siphinde sibe ukuthola ukuthi iyona capacitor "104". Manje, uma udinga capacitors Ceramic, ungakwazi kalula baqonde indlela ukubaluleka capacitance kulotshwe yeseli esithile. Futhi akudingeki ukuba bafune usizo lobuchwepheshe.
