Nooca awoodda sareiska caabiyeyaasha xadhiggainta badan waxaa lagu qiimeeyaa in ka sarreeya 1W, xitaa ilaa dhowr boqol oo watts, waxaana loo isticmaali karaa heerkulka jawiga sare. Qiimaha iska caabintu waxay u dhaxayn kartaa dhowr ohms ilaa dhowr boqol oo kilohms, oo leh saxnaanta caabbinta guud ee ± 5% iyo ± 10%. Qaybaha iska caabinta wiliga nooca awoodda ah ee qalfoofka, dabaysha, dhammaadka rasaasta iyo lakabka ilaalinta; Xaraashka wirewound waa iska caabin go'an oo ka sameysan boogta siliga iska caabinta ee qalfoofka dahaarka, siliga iska caabbinta guud ahaan waxaa laga sameeyaa nikkel-chromium, manganese-naxaas iyo alaabo kale, qalfoofka dahaarka badanaa waa dhoobada alumina, agabka daboolka ayaa daboolaya varnish, silicone, rinji, ceramics, qolof aluminium iyo wixii la mid ah. Iska caabiyeyaashayada sibidhka ee caadiga ah, iska caabiyeyaasha daasalka aluminium ee trapezoidal, iyo iska caabiyeyaasha ripple dhamaantood waxay ka tirsan yihiin iska caabiyeyaasha siliga xoog badan, oo wata agab kala duwan.
Waa maxay sababta ay armaajooyinka kontoroolka ugu baahan yihiin inay isticmaalaan iska caabiyeyaasha siliga koronto ee awoodda sare leh?
Muhiim ma aha in la isticmaalo awood sareiska caabiyeyaasha xadhiggaloogu talagalay armaajooyinka kontoroolka, laakiin halkii sare ee awoodda sare ee xargaha xargaha waa inay buuxiyaan shaqada shuruudaha xakamaynta, haddii aan loo baahnayn, lama isticmaali karo. Qaar badan oo armaajooyinka kontoroolka ah uma baahna caabiyeyaasha silig-bound awood sare leh, kuwa sameeyana waa dhif. Tusaale ahaan, tiro badan oo ka mid ah armaajooyinka caadiga ah ee matoorada caadiga ah uma baahna iska caabiyeyaasha silig-wound ee awoodda sare leh, halka inta jeer ee mootada bilawga armaajooyinka kontoroolka ay u baahan yihiin iska caabiyeyaasha siligga awoodda sare sida iska caabiyeyaasha biriiga.
Awood sareiska caabiyeyaasha xadhiggainta u dhaxaysa 5mΩ ilaa 100KΩ. Resistors Wirewound waxaa laga sameeyaa silig Nichrome ama silig naxaas Manganese, ConocoPower boogta tuubooyinka dhoobada, resistors RX20 loo qaybin karaa laba nooc: go'an iyo debuggable.
Faa'iidooyinka iska caabiyeyaasha xargaha korantada sare: iska caabin sax ah oo sarreeya, buuq yar, xasilloon oo la isku halleyn karo, heerkulka yar ee isku-dhafka ah, wuxuu u adkeysan karaa heerkul sare, heerkulka deegaanka ee 170 ℃ wuxuu wali si caadi ah u shaqeyn karaa.
