Trimmer resistor - enye izinto ezinkulu electronic

Kwiisekethe mihla ziye lisetyenziswa kwi ezahlukeneyo ulungiso resistors. eziphambili parameter izinto ezinjalo - eli ukuxhathisa zombane. Ezona mpawu yesibini iindawo ezinjalo ingaquka ukusasaza mandla aphezulu asetyenziswa kunye impazamo rating uxhathiso. Kuxhomekeka ukutshintsha ukumelana kunokwenzeka, bahlule constants kunye eziguquguqukayo olu hlobo inamacandelo radio. Uhlobo lokuqala element siyakwazi ukumelana oluthile alunako ukutshintshwa. Ngenxa yoko, lo ngumfuziselo wesibini yeli candelo zingatshintsha le isici. Le ndawo iklasi ziquka potentiometer, rheostat, resistor bume kunye lokucheba. I ezimbini zokuqala kakhulu esetyenziswa elektroniki ngamandla, ezimbini zokugqibela kakhulu esetyenziswa kwizixhobo microelectronic.

On variable uyilo kunye trimmer yahlulwe provoloochnye kunye besprovoloochnye. Kuxhomekeka ngendlela utshintsho ukumelana bokwahlula rotary kunye isilayida.

Uyilo kakhulu elula kwi provoloochnogo resistor. Njengoko isiseko, esisebenza ngayo njengoko i-ring ubushushu. Olu phawu inxeba ucingo, iziphelo ezo iqhotyoshelwe 2 abafowunelwa kakhulu radioelement. Top kumqheba iseti kunye nesilayidi (kufanele uvumelane snugly ngekhonkco) kwaye ifakwe kukho umsantsa isibonelelo ujikelezo screwdriver. Xa inyathelo elilandelayo ukuseka uqhagamshelwano engundoqo, nto leyo kuza kudibanisa phakathi terminal engundoqo kunye ukujikeleza element. Inyathelo lokugqibela mveliso unomathotholo efana trimmer, sikuko kokufaka isakhiwo badityaniswa izindlu zokuzikhusela. Ngoko ekhangela ngokufutshane chain zeteknoloji wokwenziwa kula macandelo. Ukuba umba wabelwe eklasini besprovoloochnyh ngoko yokutsiba silungelelanise ngokubhijela wire - ring senziwe Heating ayikho, kwaye sele kwaoko evela material eliphezulu amelane (kaninzi - kukho izinto umhlaba kunqabile ukuba ixabiso eliphezulu kakhulu). Ixabiso Iindleko amacandelo ezenziwe ngale ndlela, ngaphezu kwimeko yokuqala, yaye ngenxa yokuba okwangoku zande.

Le nto elektroniki wafumana ukusetyenziswa kakhulu kwi zigaba wokukhulisa (yayo ilawulwa nge inzuzo). Xa resistor igalelo olubekwe ukumelana rhoqo, kwaye kwi output - kunye variable. Emva kokuba scheme ukuvalwa ibandla yokubathumela element yokugqibela ekhethiweyo ezinqwenelekayo inzuzo factor. Kule slot ojikeleza de de oluthandwa inqanaba lomsebenzi. Emva Ukumiswa ngokupheleleyo, ivanishi isicelo phezu (ukuya resistor). Icandelo Trimmer ukuze bazakhele Tyhila (ngokuthinta, ukungcangcazela, ukuwa) yaye ke kwakhona ukuba ukunyenyisa scheme. Ukuze uphephe oku, kwaye isicelo lacquer phezulu ngenxa ukulungisa ixabiso uxhathiso.

Linganisa ukubaluleka kwendima edlalwa trimmer kubugcisa isilawuli bale mihla (hayi kuphela), kunzima kakhulu. Kodwa kukhuselekile kuthi ngelo candelo amaza a lisetyenziswa izixhobo phantse yonke elektroniki. Kwaye trimmer minyaka yonke abayifumanayo ukwandisa isicelo izisombululo wesiphaluka omtsha.
