Zeziphi ezi ntlobo zahlukeneyo resistors

Xa ekudaleni nemizobo yobugcisa iinkcukacha eziyimfuneko. Resistors ziphakathi ibalulekileyo. Kunzima ukuba nomfanekiso-nkqubo nenxalenye ezintlanu, naphi na apho bafumana izicelo zabo.

Yintoni a resistor

wadalwa Eli binzana Bulelani Latin "Resisto", nto leyo iguqulelwe ngokuthi "ukumelana." Iziqalelo parameter data engundoqo, enika umdla luvukelo wesiqhelo. Oku ulinganiswa ohms (inani ohms). amaxabiso wesiqhelo ezibonisa izindlu isixhobo. Kodwa ke kwabantu ngokoqobo inokuba nomahluko kancinane. Ngokuqhelekileyo, le ezincinane kubandakanya ukusebenzisa iiklasi kunye nokumelana ngqo. Ezi manje. Ukuba abayi kuwaqonda into malunga neentlobo resistors, photo ukunceda ukuyilungisa.

Iiklasi okuchaneka nokumelana

Ngokubanzi, kwiiklasi omkhulu umdla. Bangabantu ezintathu:

1. Kuqala. Ubonelela ezinxaxhileyo of ekhulwini ukuya ku abahlanu eliyimali utshilo.
2. Yesibini. Ubonelela ezinxaxhileyo owawufikelela ekhulwini alishumi kwexabiso elibekiweyo.
3. Okwesithathu. Ezi zibandakanya izixhobo ukuba isayizi lungakho ukufikelela amabini ekhulwini kwixabiso elifanelekileyo.

Yaye kuthekani ukuba loo lunomahluko ezinkulu azamkelekanga? Kukho resistors ngqo, ezinika imibono liphezulu umahluko:

1. 0,01%.
2. 0,02%.
3. 0.05%.
4. 0.1%.
5. 0.2%.
6. 1%.
7. 2%.

ezinye iinketho

Of zibalulekile kwi element yokukhetha parameters zeesekethe zinciphisa i ombane ukusebenza, ukusasaza amandla wesiqhelo kunye lobushushu ukungavumelani yokunganyangeki. Lo mzobo yokugqibela ibonisa indlela utshintsho yandile yesidanga kuya kuchaphazela ukusebenza ifowuni yakho. Xa eli nani inyuswe okanye ihliswe kuxhomekeke izinto ezisetyenziswayo xa kwenziwa imveliso. Rated amandla ukusasaza ubonisa ukusetyenziswa into kumda. Ukuba uphawu unikezelo mkhulu ngaphezu ukuqhubekekiswa, lo resistor awukwazi ecima. Xa umda ombane yokusebenza Ukufezekisa salathisi enjalo, apho ukusebenza oluthembekileyo izixhobo ziya kunikwa.

Eyona eziphambili ze resistors

Zine:

1. Non-nezilawulwa:

a) njalo.

2. akulawulwa kwamanye:

a) ukusika;

b) nesebenzayo.

3. Thermistors.

4. Photoresistors.

resistors akulawulwa esisigxina sahlulwe akukho ucingo /. Xa uhlobo yokugqibela yi olunye ucingo isilonda sibe elikhulu resistivity. Ibonisa resistors ilungiswe ngohlobo iingxande, zazo kwizigqibo ezithile. Ixabiso le wokuzibhubhisa amandla avumelekile bucaciswe phakathi ngokomzekeliso yemigca. Ukuba ixabiso uxhathiso akukho ku ezahlukene ohms 0 ukuya-999, iiyunithi zemilinganiselo hayi uqobo bucaciswe. Ke ukuba eli nani ngaphezu kwewaka, okanye yezigidi, izihionipho kusetyenziswa ohms kunye megohms, ngokulandelelana kwazo. Ukuba lo mzobo saboniswa kuphela malunga okanye zinokutshintsha izicwangciso, ukufaka *. Ngenxa yale iintlobo ezahlukeneyo resistors parameters ziyahluka lula.

izinto ezitshintshayo

Siza kuqhubekeka ukuqwalasela iindidi resistors. Olu hlobo sixhobo kusengenziwa ngokuba variable. Bathi nokumelana ekungabonini ukusuka kwiqanda ukuya ixabiso eliyimali. Kananjalo eli xesha lisenokuba / wire. Uhlobo lokuqala ukutyabeka conductive oluthi lusetyenziswe nembasa Heating njengoko arc, apho qha luvela isusiwe ukuba zixhonywe asi. kwayo yenziwa xa efuna ukutshintsha ixabiso uxhathiso. Kuxhomekeka eziliqela iinkalo esi sicwangciso inokuguqulwa kubudlelwane ezinjalo:

1. Linear.
2. Lwe logarithm olusezantsi.
3. Kobudlelwano.

resistors Trimmer

Abanalo esqwini nibonise. Ukutshintsha parameters olu hlobo resistors kunokwenzeka kuphela screwdriver okanye oluzenzekelayo isixhobo / mechanical ukuba ungakwazi ukwenza umsebenzi wayo. Oku kunye neentlobo ngaphambili resistors ezisetyenziswa kwiimeko apho umntu unawo amandla okulawula kubo, umzekelo, abantetho isisiXhosa.

thermistors

Ngoko wabiza izinto semiconductor, xa yombane kuwo ngesalathisi ezifana uxhathiso yahluka kunye lobushushu. Xa esehlisa indyebo yalo. Ukuba amaqondo obushushu ehlile, uxhathiso kwandisa. Ukuba inkqubo igophe ihambisa ukuya kwicala elinye (ukunyuka ukukhulisa), ngoko oku kuthiwa PTC element.

photoresists

Ngoko wabiza izinto, apho isalathisi parameter yahluka phantsi kwempembelelo zokukhanya (kwaye kwezinye iimeko, yaye umoya) abuya. Njengomgaqo, wasebenzisa photoresists ukuba nemiphumela emihle yombane. besenza kunciphisa xa sijongana ukukhanya. Photoresists babe uyilo elula, ubungakanani ezincinane uvakalelo oluphezulu, nto leyo evumela ukusetyenziswa kwabo photoelectric, izinto zokubala, ulawulo, ulawulo kunye nokulawula izixhobo, abenzi boluvo kunye nezinye izixhobo ezininzi.
