Ndezvipi marudzi akasiyana resistors

Paaisika hwokugadzira chati zvakakodzera mashoko. Resistors vari pakati inokosha. Zvakaoma kufungidzira anorimwa kunyange zvikamu zvishanu, chero vanowana chikumbiro chavo.

Chii chinonzi resistor

The izwi akasikwa kunokwana Latin "Resisto", iro rinogona kushandurudzwa se "kukunda." Huru parameter Data okunze, iro rinopa kufarira ndiyo aizviti nemishonga. It unotaurwa ohms (nhamba ohms). Chezita tsika zvinoratidza mudziyo dzimba. Asi nhamba chaiyo aigona kunge siyanei. Kazhinji, nuance ichi zvinosanganisira kushandisa zvidzidzo uye zvakarurama tolerances. Izvi isu funga ikozvino. Kana musingadi kunzwisisa chinhu pamusoro mhando resistors, mufananidzo kubatsira kuchigadzira.

Makirasi zvakarurama uye tolerances

Kazhinji, mukuru mubereko makirasi. Ivo vatatu:

1. First. Inopa nokuti zvarakasiya anosvika mashanu muzana kubva ati chezita ukoshi.
2. Second. Inopa nokuti zvarakasiya chinogona kusvika gumi muzana vaizviti ukoshi.
3. Third. Izvi zvinosanganisira namano kuti saizi zvarakasiya anogona kusvika makumi maviri muzana vaizviti ukoshi.

Uye chii kana zvarakasiya makuru kwakadaro zvisingagamuchirwi? Kune nemazvo resistors, izvo zvinopa pfungwa vaifanira musiyano;

1. 0.01%.
2. 0.02%.
3. 0,05%.
4. 0.1%.
5. 0.2%.
6. 1%.
7. 2%.

vamwe mikana

Of zvinokosha kukosha wokusarudza chingaita redunhu parameters vari Kuderedza kushanda voltage, chezita simba nounzenza uye tembiricha coefficient kurwisa. Zvapedzisira nhamba inoratidza sei kuchinja dhigirii pamwero huchachinja nokushanda mudziyo. Mumufananidzo uyu anogona ngazviwedzerwe kana ungaderedza zvichienderana akashandisa zvinhu zviri kugadzirwa. Rated simba nounzenza inoratidza muganhu maatomu akafanana kushandiswa. Kana romugove hunhu mukuru inogona kupatsanurwa, kuti resistor anogona kungoti kutsva. Nokusanyanya nekubata voltage dzinoziva nechiidzo yakadaro, sezvamakaropafadzwa akavimbika nokushanda midziyo zvicharangarirwa.

The Mhando chikuru resistors

Ndivo vana:

1. Non-inodzorwa:

a) kuramba.

2. Unregulated:

a) kudimburira;

b) variables.

3. Thermistors.

4. Photoresistors.

Unregulated wakaiswa resistors zvatowedzera akakamurwa hapana / waya. Mukupera mhando humwe ronda waya sezvo kuva guru resistivity. Kuratidza pazvinhu resistors muchimiro rectangles, iyo dzakananga mhedziso. The kukosha zvinobvumidzwa simba nounzenza raanotaura mukati munhu geometric nhamba. Kana kurwisa mutengo iri kuwanda 0 kusvika 999 ohms, nokuyerwa dzakabatana havasi yemanyorero kutaurwa. Asi kana mufananidzo uyu anopfuura chiuru, kana miriyoni, ari mazita anoshandiswa ohms uye megohms, ukuwo. Kana nhamba yakaratidza chete pamusoro kana zvinogona kuchinja panguva pazviruva, wedzera *. Nokuda kwaizvozvi mhando dzakasiyana-siyana resistors parameters nyore kusiyana.

shanduka zvinhu

Tikaramba kufunga marudzi resistors. Izvi mhando mudziyo vanongogona achanzi shanduka. Ivo nemishonga ingabva razero kusvika aizviti ukoshi. Vanogonawo kuva / waya. Chokutanga mhando chinhu conductive unhani kuti rinoshandisirwa dielectric bwendefa sezvo chinhu chakakombama, sezvamakaropafadzwa vakashinga kuonana inodedera kuti akatasva ari ekisero. Bato racho rinoitwa kana aida kushandura kuramba mutengo. Zvichienderana dzinoverengeka zviri yokuvira ichi inogona kuchinjwa muukama dzakadaro:

1. Linear.
2. Theorem.
3. Exponential.

Trimmer resistors

Havafaniri kuva projecting akabatana. Ukatora parameters iyi mhando resistors runobvira chete ane sikurudhiraivha kana otomatiki / zvokuimba zano kuti anogona kuita ayo ushande. Ichi uye yapfuura mhando resistors anoshandiswa zviitiko apo munhu ane simba waidzora kwavari Somuenzaniso, vakurukuri.

thermistors

Saka akadana semiconductor okunze, apo magetsi wedunhu umo nechiidzo akadai kurwisa kunosiyana-siyana pamwe tembiricha. Paakanga kutura zvibereko zvayo. Kana tembiricha zvinoderedza, ari kuramba inowedzera. Kana munyonga kwacho kunoita rimwe divi (magnification inowedzera), zvino ichi anonzi PTC maatomu akafanana.

photoresists

Saka akadana zvinhu, umo parameter indekisi kunosiyana-siyana pasi pokudzora chiedza (uye dzimwe nguva, uye remagetsi) nemwaranzi. Kazhinji, akashandisa photoresists kuva zvakanaka photoelectric kushanda. kurwisa kwavo zvinoderedza kana vari pachena kuti chiedza. Photoresists vane nyore design, diki kukura uye yakakwirira nehanya, izvo anobvumira kushandiswa wavo photoelectric, counter, kuzvidzora, murau kuzvidzora namano, sensors nezvimwe mano mazhinji.

mhedziso

Apa pane resistors vakadaro, mifananidzo, chinangwa, musimboti kushanda namano izvi.
