Resistor melemo le kgetho tsa bona

Resistor - ntho oa potoloho, e leng o sebeletsa ho fokotsa jwale ho eona. Hape, resistors li sebelisetsoa ho fokotsa khatello ea kelello ka ho ba bang libakeng tse le ho arohana ka morao-rao tsa lona karolo. Ka lipotoloho motlakase resistors ba denoted ke dikhutlonne tse nyenyane le para ea Pins (e mong ka mahlakoreng a mabeli a shebaneng le). Naheng e 'ngoe resistors li emeloa ke robehileng mola.

Resistors ke entsprechen ka sehloohong tse tharo:

1. Standard hanyetsa (resistor makgabane).
2. Mamello.
3. Matla dissipation.

Resistor makgabane - boleng ba hanyetsa tsa bona ka lebitso, ke hore, boleng ba boletsweng ke moetsi. Ipolela ho hanyetsa e lekanngoa ka ohms. Resistors li sebelisoa hoo e batlang e le liindasteri kaofela, ho ba le ho honyenyane le disebediswa tse motlakase. Sena se etsa hore e khōlō ea mefuta e fapaneng ya ho hanyetsa makgabane. Leha ho le joalo, ho na le resistor makgabane, tse bokahohleng.

Rerela resistor le itseng boleng nepahetseng ipolela hore ke ho le thata haholo, kahoo sebelisa boleng ena e le mamello ya. Ka mohlala, haeba ka boletsweng ka lebitso hanyetsa lekanang ohms 10, ha e le hantle e ka ba ka 10.1 9,98- ohms. Sena se bitsoa ho khoneha tolerances phoso le lekanngoa ka peresente ya.

Matla dissipation - mong oa mekhoa e bohlokoa ka ho fetisisa beha resistor. Hlalosa hore na ke bolelang boleng fanoeng. Resistor, eo ka eona le motlakase hona joale o sa khaotse a halefile. Futhumatsang itšetlehile ka bokhoni ba morao-rao. E mong le e resistor na le itseng mocheso moedi ka nģ'ane ho eo e overheats le chesa ka ntle. Dissipation - ke boleng ba matleng a ea motlakase hona joale, ao ho 'ona ho resistor tla chesa. Joaloka melemo ya resistors, matla dissipation - ke kamehla bakeng sa e mong le e ba bona ba. Ho e bontšoa ke 'moetsi. Ka lipotoloho motlakase matahoa a sa itlhompheng matla a resistor le eona e lokela ho boletseng. Kgethwa lona sebediswa sekametse, tshekaletseng le paatsepama mela. From setšoantšo ka resistor meleng letšoao ke tlhakantsuke khethehileng bontšang makgabane fapaneng matla. makgabane tloaelehileng ka merero e nyane Range ho pakeng tsa 1/8 Watt le Watts tse hlano. Matla dissipation bakeng resistor efe kapa efe ka balwa tloha molao Ohm bakeng subcircuit. Ho hlaloseha e, o lokela ho tseba hore hona joale ka balebeli ba potoloho le ba ipolelang boleng ba resistor.

dikatlholo tsohle di ditekanyetos hanyetsa. Ke hore, ho na le ba bang ba makgabane tekanyetso resistor. makgabane tsena, le eena, o boetse o hlophisitsoe ka mela ea sefahleho melemo ya resistors. Bakeng sa letoto lena DC moeti 6: E6, E12, E24, E48, E96, E192.

Bakeng sa divariabole jwale sebelisoa ka linako tse ling feela har'a E6 le E3. linomoro e le mabitso a mela e emela palo ea dikatlholo khoneha letotong lena. Ka mohlala, a mangata a malumeli E6 akarelletsa feela hanyetsa khoneha latelang: 1,0; 1.5; 2.2; 3.3; 4,7; 6,8.
