Waihoʻoluʻu helu kuʻina mea pale mū holapū. Inoa mana resistors noaia

Ka uila i puhi ai no kaʻikena hoʻoponopono resistors i hoʻohana. Available i nuiʻano o ia mau mea. E hoʻoholo i loko o nā mea a pau likeʻole ma o nā lāliʻi, no kela a me keia hoʻokomo o hōʻailona o ka mea pale mū holapū. Ka mea i hāliu aku i loko o kekahi aoao, ke kaumaha ma muli o ka hooponopono hou.

'ano o nā resistors

Mea pale mū holapū - ka mea i loaʻa ka uila ia'ku, kona papa kuhikuhiE kuleana pili i - kaʻikena ke kaupalenaʻana kaapuni. Hana produces acee? Iuo oeiia o resistors ia i loko o ka likeʻole ma o ka iiaie oaoieei manaʻo. Ko lakou Mea Maluna ua lawe mai i loko o kekahi aoao, i kekahi o ia mau mea - i ke ano o ka loli ma ke kū'ē'ē mai. E like me keia Mea Maluna distinguishes 3 ke ano o na resistors:

1. Haka pono resistors. Lakou mea e hiki ke ana hoʻololi i ka nui o ka e kū'ē'ē mai. Ma ka manawa i oleloia ai, ka mea, ua mahele ia i mau hoailona ia mea: nui a me kekahi noi. Ka hope, ua māheleʻia aʻela ma ka hookohu ana i waho e neʻe, kiʻekiʻe-impedance, kiʻekiʻe-anakahi uila a me ka kiʻekiʻe alapine (frequency).
2. Ee iaaanu aey resistors (ka mea, i kapaʻia ai ka hoʻoponopono). Ua ka hiki e hoʻololi i ka ia'ku ma ka hooponopono ana kumu. Ma ka manao ka mea, i loaʻokoʻa. Aia mea he make up me ka kuapo, papalua, Triple (oa ma ka ia (axis) ua lako pono me elua a ekolu mea pale mū holapū) a me na mea he nui 'ē aʻe? Ueo.
3. Trimmer Resistors. Ua pili wale i ka AUOO o ka oaoieei-lima kūlana kiʻekiʻe. holo kino ka mea, e loaʻa wale nō ma lalo o kekahi screwdriver. Ua hua mai la i ka nui helu o kekahi mau ka hoʻololi 'ana o kēia mau resistors. Ka mea, i hoʻohana 'ia i loko o nā' ano o ka uila a me ka mīkini uila no HEN, mai papa i ka nui hanalima nā mea hoʻonoho.

Kekahi ano kūkā resistors i hoike ia ma lalo nei i hoike mai ai i loko o nā kiʻi.

Na Mea Maluna hana o ka piʻiʻana eiiiiiaiou

Aia i 3 walaʻauʻana ano o ka piʻiʻana lolouila eiiiiiaiou, kaʻikaʻi, pai a me micromodules. No kēlā me kēiaʻano o ka mea hoʻonoho nō kona hehee wale, e lauwili nui nā ma ka nui a me ka mea i manao ai. Hoʻohana 'ia no ka' ilikai ka piʻiʻana resistors, capacitors a me semiconductors. Ka mea e loaʻa me ka lele hiki aku ai, i ka mea hiki ke soldered i loko o ka huakai kaapuni. Aie i ka miniaturization o mīkini uila no, i kēia iaoia ua kiʻekiʻe o losing pilina.
PCB hoʻohana he uuku-pepa paia māhele i hiki aku ai no ka soldering i ka paiia kaapuni papa , a me ka ia. No kēia mau i huiʻia me ka huakai kaapuni māhele i ka leo nā pale poʻohiwi. I paiia pilina me ka nui loa kōkua emi ka nui o ka uila huahana.

No ka paʻi palapala a me ka piʻiʻana mikromodulnogo pinepine hoʻohana smd-mea pale mū holapū. Ka mea, ua nui loaʻuʻuku ma ka nui, oluolu e hoʻononiakahi me ka mīkini pū i loko o ka pai huakai kaapuni papa a me ka anakahi iki-modules. Ka mea i loaʻa i loko o kekahi palena iki ia'ku, ka mana, a me ka nui. Ka holomua mīkini uila no ka mea,ʻano nui hoʻohana smd-mea pale mū holapū.

Palena iki ia'ku a waihoʻoluʻu paʻa ka mana resistors

Maʻamau ia'ku, i hoike ia ma ohms a megohms kiloomah, ia mea he walaʻauʻana ano o ka mea pale mū holapū. Keia waiwai ua hoike mai ia ma ka huakai kaapuni mau kiʻikuhi i, ka mea, ua hoopili pololei i ka mea pale mū holapū ma alphanumeric kivila. Ma nā makahiki, pinepine Ua noi 'ia nā pōpō-kivila mai resistors.

Ka lua o ka mea nui wale ano o ka mea pale mū holapū - ia ka mana dissipation, ka mea, ua kaheaia ma watts. Kekahi mea pale mū holapū ma ka hele pono ma ia mea pii kai, a laila dissipates. Inā keia mana aku i ke ana waiwai o ka mea pale mū holapū nā pūʻulu i ka lukuia'na. Ma lalo o ka mea maʻamau notation mana resistors ma noaia kokoke manawa e noho ana, ua nui ua pinepine pili a me kona hale noho.

Ke ahonui, palena iki ia'ku a me kona kaukaʻi ma ka wela

O ka nui o ka hewa, a me haiahū kūmau mai ka palena iki cia, ana ma ka pakeneka. He mea hiki ole i ka pono paka i ke koi mea pale mū holapū me ka ia'ku waiwai ua koi 'ia e ka haiahū kūmau mai ka hoʻoholo ma mua waiwai. Ka hewa ua hōʻike 'ana ma luna o ke kino, pinepine i loko o ka palapala o ke kuhi o nā pōpō kaula. Ua Ua oaeuiinoe like me ka pakeneka o ka palena iki e kū'ē'ē mai cia.

Kahi neia manawa, ua nui fluctuations ma ka wela, he nui ia'ku waiwai i wela kaukaʻi a mahana kaʻi lau waiwai o ka ia'ku, hua h ÷ ailona - TCR like ana ma ka pili huahelu o ka ppm / ° C. TCS hōʻike i kekahi hapa o ka palena iki ia'ku o ka mea pale mū holapū hoʻololi ina ka Ambient piʻina (emi) ma ka 1 ° C.

Conditional mea kiʻi notation mea pale mū holapū huakai kaapuni

I ka unuhi aku la ia wahi i puhi ai pono ana i kona akua o GOST 2.728-74 conditional ma Kimia hōʻailona (ASB). Ka mea pale mū holapū o kekahiʻano - mea he rectangle 10x4 mm o. At kiʻi kona kumu i hanaia no nāʻano o nā resistors. Ma waho ASB, he inoa koi 'ia ka mana resistors ma ka huakai kaapuni, e kōkua ai i nā kona Ikepili no troubleshooting. I ka papaʻaina ma lalo e helu i ka ASB ikaika ia'ku, e hoike ana i ka mana dissipation.

Aia ma lalo ke kiʻi hōʻike i ka haka resistors o kekahi mana.

Conditional mea kiʻi notation o ee iaaanu aey resistors

ASB ee iaaanu aey resistors e pili ana i ka manaʻo i pono i paa resistors, e like me ka moku'āina maʻamau GOST 2.728-74. I ka papaʻaina hōʻike i ke kiʻi o kēia mau resistors.

Ke kiʻi DEBFULLNAME a me trimmer i hōʻike 'ia ma lalo nei.

Maʻamau inoa resistors

International mau hae e Kû ke i ka palena iki ia'ku o ka mea pale mū holapū i loko o ka huakai kaapuni a ka mea pale mū holapū mea he wahi okoa. Na rula o keia notation, pu me Eia kekahi laʻana o ka examples i ike ia ma ka papaʻaina.

Ka papaʻaina hōʻike i ka inoa i loko o nā manaʻo o ka ikaika e kū'ē'ē mai resistors i ka alphanumeric kivila, mua he mea he laulā kumukuai o ka ia'ku, alaila, na naehana ana. Ke kumu nui kino o ka mea pale mū holapū i mahaloia ma kikohoʻe signage kahi o ka comma, e hoʻohana i ka palapala ina ia mea ohms, alaila, kau i ka R E paha, ina kiloomah, o ka palapala K. I ka omaka megohms kahi o ka comma ua hoʻohana 'ia ka palapala M.

Waihoʻoluʻu helu kuʻina o resistors

Waihoʻoluʻu helu kuʻina o resistors Ua i ia e ia maʻalahi e kau 'ike i ka oaoieei-ano o ko lākou mau hale. E hana i kēia, pili kekahi mau waihoʻoluʻu a pau holehole mai ai o kekahi mau waihoʻoluʻu. Just inoa holehole mai ai i ka 12 okoa'ōniʻoniʻo. Kēlā me kēia no ia i kona mau kekahi manaʻo. Ke ano kivila Ua noi i resistors kae ma kona haʻahaʻa pololei (20%) ua pili i ka loloa 3. Inā i ka pololei o ka luna, me ka ia'ku hiki ke ike nei 4 holehole mai ai.

I ka kiʻekiʻe miomio mea pale mū holapū ua noi 5-6 holehole mai ai. Ma omaka he 3-4 holehole mai ai, i ka mua elua ho i ka ia'ku waiwai, i ke kolu o ka loloa - keia mea i ka multiplier, ka mea, ua hoonuiia ma keia nui. Next koa a ka miomio mea pale mū holapū. I ka omaka maupaʻa 5-6 holehole mai ai i 3 hoʻopili like i ka ia'ku mua. Next koa - mea he ololi, 5th loloa hoʻopili like i ka pololei a me ka 6th - ana wela kaʻi lau waiwai.

E decrypt i keʻano nā loina o resistors, eia Lookup papa.

Resistors SMD

Ili honua Mount - keia mea ka wā o nā lāliʻi a pau i luna o ka moku, mai ka paiia huakai kaapuni meheu. Ma keia hihia, mai? Eou nā lua no ka piʻiʻana eiiiiiaiou, ka mea, e soldered i ka meheu. No keia mea hoʻonoho hana produces he ākea huahelu o ka smd-eiiiiiaiou: resistors, diodes, capacitors, mea uholo uila na manao ona. Mau kumu, ua oi aku ka li a technologically hoʻomākaukau no ka hana nona iho i ua ahakanaka la. hiki me ka nui loa hoʻohana smd-eiiiiiaiou emi ka nui o ka uila huahana. ʻili mauna uilaʻoe kokoke piʻi aʻela a pau'ē aʻe? Ueo.

A me na pono a pau o ka noʻonoʻo mea hoʻonoho ka mea, i ka helu ana o drawbacks.

1. I paiia huakai kaapuni a ka papa i ma keia enehana, ka makau a me ka 'ē aʻe ma paʻi hawewe wahie, e like me keia smd-poino eiiiiiaiou.
2. Mau eiiiiiaiou e makau o overheating i soldering no ka mea, o ka mea oko ikaika, ka mea hiki ke crack temeratury. Kēia kina mea ole, e huai ae, ia IeAUPIIe, IAa IO ia lŘlŘ i hana.

Maʻamau inoa smd-mea pale mū holapū

Mua-smd resistors i okoa nui like 'ole. Ka uuku nui - 0402, he uuku oi - 0603. Ka loa e holo mai ana smd-mea pale mū holapū nui - 0805, a oi - 1008, na kēia nui like 'ole 1206 a me ka nui - 1812 resistors i uuku loa ka nui a me ka loa haahaa mana.

Inoa smd-mea pale mū holapū ma kekahi kuikawa laulā kuhi. Inā ka mea pale mū holapū nui o 0402, i mea no ka mea uuku, ka mea, ua i kaha. Resistors'ē aʻe nui like 'ole aiiieieoaeuii oko ma ka palena iki ia'ku ioeeiiaiey: 2, 5, 10%. i hāliu aku i kēia mau resistors me 3 huahelu. Ka mua a me ka lua o ia e hōʻike i ka mantissa, ke kolu - he multiplier kaʻi lau waiwai. No ka laʻana, ke kuhi 473 ua heluhelu ia R = 47 ∙ o 10 ³ ohms = 47 ohms.

All resistors, a i ka 1% ke ahonui, a me ka nui ma luna o 0805, ua hoailono aku la me ka eha huahelu. Like i loko o ka mua hihia, o ka mua na kii hōʻike mantissa denomination, a me ka ololi Hōʻike ka hope huahelu. No ka laʻana, ke kuhi 1501 kū ai: R = 150 ∙ January ¹⁰ = 1500 ohms = 1.5 kOhm. Like me, heluhelu i ke koena o ke kuhi.

Ka simplest manaʻo

Ka pololei inoa i loko o nā manaʻo o nā resistors a me na oihana mua - ka walaʻauʻana koi o ka moku'āina puke maʻamau, ma ka manao o ka uila a me ka pou huahana. Ua hoolakolako ia mau rula ma luna o nā hōʻailona o resistors, capacitors, inductors a me nā puni eiiiiiaiou. I ke kiʻikuhi Hōʻike ole wale i ka mea pale mū holapū 'ole' ē aʻe kaapuni hehee ai, akā, i kona palena iki ia'ku, a me ka mana, a me na capacitors - ka pae'ōnaehana anakahi uila. Lalo mea he laʻana o ka simplest manaʻo me ka hehee wale i hoʻokohu 'ia e ka hae.

Knowledge o nā mea a pauʻike mau Kimia notation a me ka heluhelu ana i alphanumeric nā loina i ka oihana mua o ke ano e hana ia oluolu, e maopopo i ka loina o ka hana o ka huakai kaapuni. He 'atikala discusses resistors wale a me ka huakai kaapuni a hehee wale i ka hailona.
