Kukaniza - ichi ndi chinthu chachikulu cha wailesi yamagetsi

Kukaniza - ichi ndi chinthu chosavuta kwambiri pa maulendo a pakompyuta, omwe ali ndi udindo wotsutsa makanema a magetsi omwe akuyenda mmenemo. Dzina la chipangizo ichi chinachokera ku liwu la Chingerezi lokaniza, kutanthauza kukana.

Zomwe zimatchulidwa kuti zotsutsana nazo zimayesedwa mu Ohms (Ohm, kOhm, mhhm), polemekeza wasayansi George Ohm, omwe adapeza lamulo, malinga ndi momwe kukana kwa magetsi kumagwirizana ndi chiŵerengero cha magetsi mpaka panopa.

Makampaniwa amapanga zotsutsana ndi zikhalidwe zosiyana za dzina lokhazikitsidwa. Pali mitundu itatu yokha ya zida izi: zosatha, zosinthika, zowonongeka.

Kusagonjetsedwa nthawi zonse ndi gulu lopambana kwambiri la zinthu zomwe zasintha. Thupi la chipangizo choterechi limadziwika ndi kusonyeza mtundu wa kukana, kupindula kwa kutchulidwa, kutaya mphamvu, ndi zina zotero. Kotero, inu mukhoza kuwona zinthu, momwe deta yonse imalembedwa mothandizidwa ndi zojambulajambula (kuchokera pa zitatu mpaka zisanu ndi ziwiri zojambula pamtanda). Kuti muwerenge mfundo izi, muyenera kugwiritsa ntchito tebulo lapadera, lomwe lingapezeke muzinthu zofalitsa kapena zolemba zamakono . Mtundu wachiwiri wa zolemba ndizolembedwa. Mwanjira iyi, chidziwitso chimafalitsidwa pogwiritsa ntchito zizindikiro ndi manambala. Kotero, kukana 10 ohm kungakhale ndi zizindikiro izi: MLT 10R. MLT imatanthauza mtundu wa chipangizo.

Kusinthasintha kosinthika ndi chipangizo chomwe chili ndi mayina osiyanasiyana. Pa thupi la chigawochi pali kusintha kwa zinthu (zokopa kapena mphuno zowonongeka), zomwe mungathe kuyimitsa chofunikira cha chipangizocho. Pa zipangizo zoterezi, chizindikiro chodziwika bwino chotchulidwa pamanja chimasonyezedwa mu mawonekedwe alphanumeric - malire kuchoka pa osachepera kufika pamtunda wotetezera mtengo akuwonetsedwa. Zida zoterezi zimagwiritsidwa ntchito kwambiri kuti zisinthe ndi kusintha zizindikiro: monga momwe zimayendera mphamvu, miyeso, voliyumu, kuyendetsa nthawi zambiri pa zipangizo zamagetsi.

Kutsitsa Kutsitsa ndi chida chokhala ndi mtundu wina wotchulidwa, koma mosiyana ndi zosiyana, izi ndizosawerengeka. Zinthu zoterezi zapeza zogwiritsidwa ntchito kwambiri m'maulendo a pa wailesi. Zapangidwe kuti zisinthe ndi kuyang'ana bwino zigawo zofunika pakupanga zipangizo za wailesi kapena zipangizo zapamwamba zomwe kupezeka kwa makhalidwe sikuloledwa. Amakulolani kuti muyike mosakayikira kukana kofunikira, motero, palibe chifukwa chokhazikitsa solder ndi zotsutsana zamtengo wapatali kusankha chofunika.

Kuphatikiza pa zigawo zofunika, kulimbana kuli ndi chinthu chomwe chimatchedwa parasitic khalidwe - capacitance. Kodi parameter iyi ndi yotani? Mphamvu ya parasitic ya kukana, monga lamulo, ndi yaing'ono kwambiri ndipo sichikhudza kwenikweni chilichonse. Ziyenera kuganiziridwa pokhapokha pojambula zipangizo zamakono. Mphamvu ya parasitic ili pakati pa mapeto a element; Zikuoneka kuti kampaniyo imagulitsidwa kuti ikhale yosagwirizana. Ndiponso, chidziwitso chingabwere pakati pa mbali ndi zozungulira za PCB ndi zigawo zina.

Poganizira mwachidule za zinthu monga kupeweratu, timatha kumvetsa zambiri zomwe zimapezeka m'mabuku opangira zamagetsi.
