Kuri-247 amashanyarazi arwanya EAK kubashakashatsi bashushanya kugirango batange pake ihamye yubwoko bwa tristoriste yibikoresho byimbaraga zikomeye, ingufu ni 100W-150W
Izi rezistoriste zagenewe porogaramu zisaba neza kandi zihamye.Rististor yakozwe hamwe na alumina ceramic layer itandukanya ibintu bya résistoriste na plaque.
Eak yabumbabumbwe na TO-247 yububiko bwa firime
Iyi miterere itanga ubushyuhe buke cyane mugihe ituma irwanya izamuka ryinshi hagati ya terefone nicyuma cyinyuma.Nkigisubizo, aba rezistoriste bafite inductance nkeya cyane, bigatuma ikwiranye na progaramu-yihuta kandi yihuta ya progaramu.
Kurwanya biri hagati ya 0.1Ωto 1 MΩ, Ubushyuhe bwo gukora: -55 ° C kugeza + 175 ° C.
EAK izatanga kandi ibikoresho birenze ibi bisobanuro kugirango byuzuze ibyo abakiriya bakeneye.Imbaraga za EAK zubahiriza ibipimo bya ROHS, ukoresheje kurangiza ubusa.

Imfashanyigisho ya Radiator Yashizwemo ingufu za firime
Menya ubushyuhe n'imbaraga:
Igishushanyo 1-gusobanukirwa ubushyuhe nigipimo cyimbaraga
Inteko y'ibikoresho bitwara ubushyuhe:
1, Hariho icyuho kubera ihinduka ryubuso bwo guhuza hagati ya pake ya résistor na radiator.Ibyuho bizagabanya cyane imikorere yibikoresho byubwoko bwa TO.Kubwibyo, gukoresha ibikoresho bya interineti yubushyuhe kugirango wuzuze ibyo byuho ni ngombwa cyane.Ibikoresho byinshi birashobora gukoreshwa kugirango ugabanye ubushyuhe bwumuriro hagati yumurwanya nubuso bwa radiator.
2, Amavuta ya silicone atwara ubushyuhe nuruvange rwibice bitwara ubushyuhe hamwe namazi bihuza kugirango bikore ibintu bisa nkibya amavuta.Aya mazi ubusanzwe ni amavuta ya silicone, ariko ubu hariho amavuta meza ya "Non-silicon" amavuta ya silicone.Amashanyarazi ya silicone yubushyuhe yakoreshejwe mumyaka myinshi kandi mubisanzwe afite ubushyuhe buke buke bwibikoresho byose biboneka.
3, gasketi itwara ubushyuhe ni insimburangingo ya silicone itwara ubushyuhe kandi iraboneka mubakora inganda nyinshi.Iyi padi ifite urupapuro cyangwa ishusho yabanje gukata kandi yagenewe kubipaki bitandukanye bisanzwe nka TO-220 na To-247.Igikoresho cyo gutwara ubushyuhe nigikoresho cya spongy, gikenera igitutu kimwe nibikorwa bihamye kugirango ubashe gukora bisanzwe.
Guhitamo ibikoresho byuma:
Ibyuma bikwiye nibitekerezo byingenzi muburyo bwiza bwo gukonjesha.Ibyuma bigomba gukomeza igitutu gihamye kandi kimwe kubikoresho binyuze mumagare yumuriro utagoretse imirasire cyangwa ibikoresho.
Abashushanya benshi bahitamo guhuza DeMint TO power resistance to radiator ukoresheje clip yamasoko aho guteranya screw.Izi clip zo mu mpeshyi ziraboneka mubenshi mubakora ibicuruzwa bitanga amasoko menshi asanzwe hamwe nimirasire yabugenewe kugirango bashire clip muri TO-220 na To-247.Isoko y'isoko ifite ibyiza byinshi byoroshye guteranya, ariko ibyiza byayo ni uko ihora ikoresha imbaraga nziza hagati yumurwanya w'amashanyarazi (reba Ishusho 2)
Igishushanyo cya 3-screw na tekinike yo gushiraho
Imiyoboro ya Mounting-belleville cyangwa isabune yogejwe ikoreshwa hamwe ninzira nuburyo bwiza bwo guhuza imirasire.Abamesa ba Belleville ni bogejwe neza bogejwe kugirango bagumane umuvuduko uhoraho.Igipapuro kirashobora kwihanganira ubushyuhe bwigihe kirekire nta gihindagurika.Igishushanyo cya 3 cyerekana bimwe mubikoresho bisanzwe bigezweho byo gushiraho TO pack ya screw kuri radiator.Gukaraba neza, gukaraba inyenyeri, hamwe no gukaraba byinshi byacitsemo ibice ntibigomba gukoreshwa mu cyimbo cya Belleville kuko bidatanga umuvuduko uhoraho kandi bishobora kwangiza umurwanya.
Inyandiko z'Inteko:
1, Irinde gukoresha TO seriveri yimbaraga zirwanya inteko za SMT.
2, Ibyuma bya plastiki byubaka byoroshya cyangwa bikanyerera hejuru yubushyuhe bwo hejuru bigomba kwirindwa
3, Ntukemere ko umutwe wa screw ukora kuri résistor.Koresha ibikoresho byogeje cyangwa byogejwe kugirango ugabanye imbaraga
4, Irinde impapuro z'icyuma, zikunda kuzunguruka ku mwobo no gukora burr zangiza muri radiator.
5, Inzira ntisabwa.Gukoresha umurongo biragoye gukomeza umuvuduko uhoraho kandi birashobora kwangiza byoroshye gupakira
6, Ntugakabye kurenza urugero.Niba umugozi ufunze cyane, paki irashobora kumeneka kumpera yanyuma ya screw (impera yambere) cyangwa ifite impengamiro yo kunama hejuru.Ibikoresho bya pneumatike ntabwo byemewe.
