Ukumaka capacitors - indlela yokubhekana?

ngonyaka bayanda ezimakethe ezifuywayo capacitors Njalo zingatholakala hhayi kuphela e-Russia, kodwa futhi amazwe. Futhi abaningi babe enzima sokuqonda amalebula. ungakwazi ukuthola kanjani it out? Ngempela, endabeni nephutha, futhi idivayisi angeke uthole.

Ukuze uqale, siphawula ukuthi nekukumakwa capacitors ezenziwe kule oda:

1. Kulinganiswe ngo umthamo ezingaba sebenzisa code uphawu ehlanganisa amadijithi (ngokuvamile emithathu kuya kwemine), futhi izincwadi, lapho incwadi ibonisa iphuzu idesimali, futhi notation (UF, NF, PF).
2. Ukusuka kuvunyelwe kusukela umthamo okuzisholo (ukusetshenziswa futhi kubhekwa ezingavamile, kuncike izici futhi idivayisi uya khona).
3. OKUVUMELEKILE voltage ukalwe (ngenye ubizwa ngokuthi kuvunyelwe yokusebenza voltage) - kuyinto ipharamitha kubalulekile, ikakhulukazi lapho isetshenziswa ephezulu voltage izifunda).

Ukumakwa ka capacitors Ceramic at umthamo ukalwe

capacitors bobumba noma unomphela kukhona phakathi ethandwa kakhulu. Ngokuvamile, capacitance isiqu zingatholakala emzimbeni ngaphandle isici esithile.

1. Ukukhomba capacitors we amadijithi amathathu, ezimbili zokuqala show lapho mantissa kanye nezinga wesibili lenani base 10 ukuthola ihlelo e picofarads, isb libonisa inani amaqanda ukuze capacitor e pikafararadah. Ngokwesibonelo: 472 kwakuzosho a 4700 PF (esikhundleni 472 PF).

2. Ukumaka capacitors kwamadijithi ezine - inqubo efana owedlule, kodwa kulokhu amadijithi amathathu wokuqala ukhombise mantissa, abokugcina babe ukubaluleka base-10 ukuze uthole ukubaluleka ubuso picofarads. Ngokwesibonelo: 2344 = 234 * 10 ² PF = 23400 PF = 23.4 NF;

3. ezixutshiwe kophawu noma wokugubha nge izinombolo kanye namagama. Kulesi usonhlamvukazi kubonisa entweni (UF, NF, PF), kanye iphuzu zamadesimali, futhi izibalo - ukubaluleka capacitance esetshenziswa. Ngokwesibonelo: 28P = 28 PF 3n3 = 3.3 NF. Kunezikhathi lapho iphuzu zamadesimali okhonjiswe incwadi R.

Ukumaka ipharamitha yokusebenza kuvunyelwe voltage ngokuvamile sisetshenziswa electronics inhlangano, enziwe ngezandla zakhe. Okungukuthi, ukukhanda sezibani Fluorescent ngeke ngaphandle lakhetsiwe zinamandla ezifanele capacitors kuhlulekile. Esimweni esinjalo, lolu ipharamitha uzobe wabonisa ngemva kuka futhi umthamo bokuzisholo.

Lezi nemingcele eziyisisekelo ezisetshenziswa lapho wokugubha wenziwa capacitors. Badinga ukwazi lapho ukhetha idivaysi ezifanele. Labelling ka capacitors amazwe kukhona ukungezwani phakathi kwabo, kodwa ezivumelana evezwe zethu kulesi sihloko.

Kahle capacitor akhethiwe kuzokusiza ekwakheni amadivayisi akho, kanye neqhaza ekulungiseni akhona. Into esemqoka ukukhumbula ukuthi umkhiqizo izinga kungaba kusukela abakhiqizi eziye zabonakala ukubaluleka kwayo emakethe kagesi. Futhi lolu hlobo lomkhiqizo - ngaphezu kwakho konke okunye. Phela, ngenxa ukungasebenzi capacitor zingase zephule ingxenye ezibizayo imishini noma idivayisi. Futhi, bathembele ukuphepha kwakho.
