Inoaia TL431 datasheet: hōʻike, inoa, hoakaka

Inoaia TL431 datasheet hana i loko o ka hopena o 70s, nae, a me keia mea, ua hoʻomano hoʻohana 'ia i loko o aeoaeuneiai Radio hana a me ka hana mau. Kēia? Inoaia mea he integral kōmike hoʻokele stabilizer ana i ua hoʻomano hoʻohana i loko o kekahi mau mana na lako.

'oihana Description

TL431 datasheet i wale ekolu Pins, akā, i hūnāʻia heʻumi transistors (comparator) i loko o kona hale. I ka mana o ka noonoo maalea, a me kaʻike mau stabilizer like. Eia naʻe, ma muli o ia mau complications, ka? Inoaia i ka oi aku thermal kumupaʻa, a hou toughness ano. Ka papa kuhikuhiE hiʻona o ia i kekahi mea o ka hiki, e hoʻohana i ka mahele waiwai, e hoʻololi i ka mawaho anakahi uila noaaeeecaoee i loko o 2.5-30 V. kekahi Ke Ana Hoʻohālike haʻahaʻa kali i e 1,25 V. Ka comparator kaapuni i ua noniakahi i loko o ka huina hoonui datasheet TL431, oia no ka i kēia eiiiiiaiou:

• noniakahi mana (loa ka pilina paʻa) i maopopo kahi anakahi uila 2,5 V, a ua pili i ka inverse manaʻo kōkua o ka comparator;
• he pololei hoʻokomo o kaʻilikai;
• ka comparator ia auoiaea pākali hoʻolele, ka emitter a me ka ÿauhau o i i hui ai me ka mana hui 'ana;
• he diode no ka palekana i ka polarity reversal.

Ke pākali hoʻolele i kekahi i kā mākou e haawe o 100 Mā, a me ka i kā mākou anakahi uila o - 36 V. I mea e kiʻi kūkulu-i loko o ka comparator (niioaaonoaaiii wehe i ka auoiaea pākali hoʻolele? Inoaia) pono ma kona hoʻokomo o waiho i ke anakahi uila ma luna ma mua o ka mea i maopopo nä haumäna. Hookomoia ma ka? Inoaia hoʻokomo o anakahi uila mahele waiwai iloko olaila a mau resistors, ka mea i hookaawale ai i loko o ka hapalua o ke anakahi uila waiwai. Kēia 'o ia hoʻi ka hoʻokomo o huakai kaapuni 5, i ka auoiaea o ka mahele waiwai loaa 2,5 V. Inā mea pale mū holapū, e hoʻonui i ka ia'ku i ke comparator, e komo ia, ka mea, he pono ia i hoʻonui a me ke anakahi uila lako. Ua huli mai i keia huakai kaapuni a ke hana e like me ka zener diode loko o 2,5-36 V.

Manao a me ka laulā

Aohe mea hookahi kamepiula mana lako pa alima, ma ka a, ua ole? Inoaia TL431 datasheet. No hoi, ka mea hiki ke loaʻa i loko o aneane pau haʻahaʻa-mana lāʻau ikiʻai wale ka mana lako, no ka laʻana, kauoha no ka lawe lima kaul. Mau inoaia hiki ke hoʻohana ole wale no kona Manao iho la ia mea (zener diode no ka mana lako huahelu), akā, no hoi, e ho okumu ma luna o lākou muli o kekahi mau kukui, a audible pū waikaua. Me kēia mau manaʻo kanaka hoʻoponopono i ka ai iiiaanoaa o okoa kiko'î (akā nō kumu o anakahi uila o). He nui nā manaʻo me ka nānā 'TL431 datasheet, ma i ia mea hiki, e hoakoakoa i ka mea no ke kaōhiʻana i ke kinowai kiʻekiʻe i loko o ka ipu, ka humidity a me ka wela, kinoea puʻe a loli illuminance. I helu 'ia nā koho - i mea hiki wale, i ka hana o keia? Inoaia Ua pono maoli, ka mea a pau hilinaʻi nui ma luna o ka makemake o ka poʻe akamai.

Loa pinepine, beginners Radio amateurs hoihoi i ka mea hiki ke auou caiaiai ia e ka TL431. Mea like, a papa, nei. No laila, e hiki ke hoʻohana i ka laweia, a wahi lulu huahana KA431 KR142EN19A lima kūlana kiʻekiʻe K1156ER5h.

e hōʻuluʻulu

Noniakahi kaapuni "Texas mea paahana a" poe i loa ike loea, ka mea, i ke ākea pae'ōnaehana huahelu, oluolu i ka hana, a me ka hapanui importantly, mai ka affordable kumukuai. Manawa i kona ano, ka mea produces oi ma mua o nā makahiki he kanahā, a mea nō mahalo.
