Yeka ukuthi ukukhonjwa kombala wezinhlamvu kubonakala kanjani

Ukuphikisa - lena yinto ejwayelekile kunazo zonke, efakwe kunoma yisiphi isifunda se-elektroniki. Ingabonakala yonke indawo: kusuka kumshini wokuwasha olula kuya kwikhompyutha yanamuhla. Izinhlobo ezimbili zokumaketha zisetshenziselwa ukukhombisa izindawo zabo: okokuqala ukukhonjiswa kombala kwabamelana nendlela yokusebenzisa izindandatho ezinemibala eminingi, icala lesibili liyi-alphanumeric.

Ukuqokwa okubhalwe phansi

Endabeni yama-resistors kanye nama-capacitors amakhulu amancane amakhulu, ukumelana kwawo okunamagama (capacitances) kuphawulwe ngokusebenzisa izilinganiso ezilinganiselwe ezilinganisweni zamayunithi amaningi, futhi ngokulandelayo - ukuphambuka okungenzeka kunani elifunwayo, isibonelo: 1.5 Ohm 10%, 33 Ohm 20%. Izindinganiso ezinjalo zihlanganisa ikhodi yokumaka yama-resistors. Ukubethelwa kwama-value amanani wemikhiqizo encane kunesethi ekhethekile yezinhlamvu ze-alphanumeric. Kodwa ngesikhathi esifanayo, ikhodi ye-mnemonic, okungukuthi izindandatho ezinemibala, lapho umbala wombala wamelana nawo uhlanganisa khona, usetshenziswa emhlabeni jikelele. Ngokwesistimu enjalo, i-unit of resistance Om ibhalwe ikhodi (E), 1000 Ohm - njengo (K), mega - kakade (M). Ama-capacitances akhethekile we-resistors avela ku-100-910 Ohm abhekiswa emaqenjini e-kilo, kanti ububanzi be-100,000-910000 yi-mega-ohm. Uma kwenzeka ukuchazwa okubizwa ngokuthi yinombolo, umklami we-alfabhethi abekwe emva kwezinombolo - ЗЗЕ (33 Ohm), 1M (1 МОhm). Ukurekhoda ingqikithi yedesimali engaphansi kweyodwa ibeka amamaki alfabhethi ngaphambi kwenombolo, isibonelo, M47 (470 kOhm). Futhi esimweni sayo sonke sinomkhawulo wesimali, incwadi ibhalwe esikhundleni se-comma emva: 1E5 (1.5 ohms), 1M5 (1.5 MOhm). Ukuphambuka okuvunyelwe ngaso sonke isikhathi kuveza umkhondo wokumelana: 5%, 10%, 15%. Ukumaka umbala wokumelana kungabandakanya kokubili izinhlobo zokumaka.

Ukumaka umbala

Ihlanganisa ukubeka uphawu lwegobolondo langaphandle lensiza ngemigqa emi-3 noma ngaphezulu enemibala egqamile. Indlela ngayinye yokumibala inenani elithile lezinombolo, eveza izindawo zokumelana nombimbi. Ngokuvamile umugqa wokugcina ubeka ukubaluleka kokubekezelelana okulindelekile komkhiqizo, futhi amapheshana okuqala akhuluma ngokumelene. Isibonelo, ngokumaka okuyi-4, ukuqala kokubili kufaka ubukhulu besikhundla (Ohm), kanti okwesithathu kusebenza njenge-multiplier ngenani elibalulwe. Ukumaka umbala we-resistors kungacutshungulwa ngokubeka umkhiqizo ukuze ibhande elibanzi kanye namasongo alandela ngemuva kusondele ngakwesokunxele. Khona-ke udinga ukusebenzisa amatafula afana nokusiza ukucacisa ukubaluleka kokuhluka.

Amanye amazinga

Ukumaka umbala wabamelana nezimbangi ezingenayo akushiyi konke ngakho kungabonakali. Iqiniso lokuthi imikhiqizo yasekhaya isebenzisa uphawu lwayo, kepha lwangaphandle - elinye. Abanye abakhiqizi baze bashintshe izindinganiso, beklama uhlelo lwabo lombala. Ukumaka okungavamile kusetshenziselwa ukuhlukanisa leyo mikhiqizo eyenziwe ngokuvumelana nezidingo ze-MIL, ehluke ekukhonjisweni kwezinhloso zezimboni nezomkhaya, ingabika ngezakhiwo zokumelana nomlilo, njll. Isibonelo, i-"PHILIPS" eqinile ikhombisa ukubaluleka kwama-resistors njengoba yamukelwa yonke indawo, isb. Izibalo zokuqala zikhuluma ngama-ohms, futhi okugcina yi-multiplier. Kuncike kokunemba okuchaziwe komphikisi, uphathwa njengezinhlamvu ezingu-3-4. Ukuhluka okuvela emakhosini evamile wokufaka ikhodi kumthwalo we-semantic we-7, 8 no-9 wamadijithi wokugcina.
