Chichatara capacitors - sei kubata?

Gore negore zvakawanda pamusoro wechipfuwo misika yacho capacitors anogona kuwanikwa kwete chete muRussia, asi kupinza. Uye vazhinji kwazvo dzikatadza achiongorora zvaive pamapepa aya. Sei kuchiona? Zvechokwadi, mune nyaya yokukanganisa, uye mudziyo havagoni kuwana.

Chokutanga, tinoona kuti kupenda capacitors akaita kuti ichi:

1. Rated rokuva kuti vangashandisa coded chiratidzo raiumbwa digits (kazhinji nhatu mana), uye tsamba, apo tsamba inoratidza grade pfungwa, uye notation (uF, NF, PF).
2. The bvumidzwa zvokutsauka kubva aizviti vachikwanisa (kushandiswa uye anonzi zvisingawanzoitiki, zvichienderana unhu uye kuenda mudziyo).
3. Bvumidzwa yavose sezvavakatarirwa voltage (zvikasadaro inonzi bvumidzwa uchishandisa voltage) - kunokosha parameter, kunyanya kana anoshandiswa mukuru-voltage matunhu).

Kupenda pamusoro zvedongo capacitors pa yavose sezvavakatarirwa chinzvimbo

Ceramic kana zvachose capacitors vari pakati zvikuru nevanhu. Kazhinji, capacitance rokuti anogona kuwanika pamusoro muviri pasina chaicho chinhu.

1. Nokuzivikanwa pakati capacitors pakati digits vatatu, vaviri dzinoratidza rokutanga apo mantissa uye ekupedzisira papi ndiye kukosha pangoro 10 kugamuchira sangano iri picofarads, i.e. inoratidza nhamba zeros nokuti capacitor mu pikafararadah. Somuenzaniso: 472 kureva 4700 PF (panzvimbo 472 PF).

2. Chichatara capacitors ose digits mana - hurongwa chakafanana yapfuura, asi muchiitiko chino ari digits nhatu dzokutanga anoratidza mantissa, uye yokupedzisira ndiyo kukosha pechingoro 10 kugamuchira chiso anokoshesa picofarads. Somuenzaniso: 2344 = 234 * 10 ² PF = 23400 PF = 23.4 NF;

3. Mixed Kunyora kana kupenda pamwechete nhamba uye netsamba. Kana tsamba iyi kunoratidza kuti chinhu (uF, NF, PF), uyewo grade pfungwa, uye nhamba - kukosha capacitance kushandiswa. Somuenzaniso: 28P = 28 PF 3n3 = 3,3 NF. Pane nguva apo munhu grade pfungwa runotaurwa tsamba R.

Chokuguma parameter bvumidzwa uchishandisa voltage rinowanzoshandiswa zvemagetsi gungano, nemaoko ake pachake. Kureva kuti kugadziriswa pakati fluorescent mwenje hakuzovi pasina kusarudzwa yakakodzera voltage kuti vakundikana capacitors. Pakadaro, parameter ichi sezvinoratidzwa pashure Kutsauka uye chezita chinzvimbo.

Ndivo zvinokosha parameters kushandiswa kana chokuguma anoiswa capacitors. Vanofanira kuziva pakusarudza yakakodzera mudziyo. Kunyora kuti kupinza capacitors vane kusawirirana kwavo, asi zvikuru maererano yedu ataurwa munyaya ino.

Zvakanaka yasarudzwa capacitor achakubatsira mukusika kwako namano, uyewo kupa rokugadzirisa munazvo. Chinhu chikuru kuyeuka kuti unhu chigadzirwa kunogona chete kuva kubva vagadziri kuti vakaratidza vanokosha ravo magetsi kumusika. Uye nekuti chigadzirwa yepamusoro mhando iyi - kupfuura zvimwe zvose. Pashure pezvose, nokuda mumwe atadze kushanda zvakanaka pamusoro capacitor anogona kutyora anodhura chezvinonhuwira midziyo kana mudziyo. Uyewo, vanogona kuvimba kwako vakachengeteka.
