Ulwazi lwe-resistors

1. Yintoni ukuxhathisa

Isenzo sokumisa umsinga kuthiwa ukuchasana.Isixhobo esinexabiso elithile lokumelana kuthiwa sisiqalelo sokumelana.I-R(Resistor) ichazwa ngesiNgesi.

2. Iyunithi yokuchasa

Iyunithi esisiseko ye ohm Ω iiyunithi zayo zolwandiso zinewaka o K Ω megohm M Ω

3. Ifomula yoguqulo yeeyunithi zomlinganiselo:

1 m Ω = 10 ³K Ω = 10⁶Ω

4. Uhlobo kunye nesakhiwo sokumelana:

4.1 Ukuhlelwa kwezinto:

CF:Ifilimu yeKhabhoni

TF:Ifilim engqindilili

MF:Ifilimu yesinyithi

Wirewound

4.2 Ukuhlelwa ngokwesakhiwo:

Ukuxhathisa okuzinzileyo.(R)

Ukuxhathisa okuguquguqukayo.(S-VR)

Ukuchasana okuguquguqukayo (VR)

4.3 Ukuhlelwa ngokwemilo:

Ukumelana nomsesane wombala

Ukuchaswa kwamaphepha.

ukukhutshelwa ngaphandle

4.4 Ukuhlelwa ngokwamandla ahleliweyo:

1/16W, 1/8W, 1/4W, 1/2W, 1W, 2W, 3W… Kwaye njalo.

Amandla ayakwazi ukwahlula ngokuma kunye nobukhulu bayo.Ubukhulu bevolumu, amandla amakhulu.

5. Iimpawu eziphambili zokuxhathisa:

Iiparamitha eziphambili zobugcisa zokumelana ziquka ixabiso lokumelana, amandla alinganisiweyo, uluhlu lwephutha kunye nokunye.

6. Indlela yokumela ukuchasa:

Amaxabiso okumelana kunye neempazamo zabaxhathisi zinokubonakaliswa ngokubanzi ngamanqaku edijithali aprintwe kwi-resistors okanye ngamakhonkco ombala.Kuphela kubonakaliswa ngamanani kuchazwe ngezantsi.

Ukusebenzisa amanani amathathu:

Izichasi ze-SMT ezinempazamo ye-5% ngokuqhelekileyo ziprintwa kwi-resistor ngenani leedijithi ezintathu, kunye needijithi ezimbini zokuqala ezimele amadijithi abalulekileyo kunye nedijithi yesithathu emele ukuphindaphinda kwe-10n.

Imelwe ngamanani amathathu:

Izichasi ezichanekileyo zidla ngokumelwa ngamanani amane, amadijithi amathathu okuqala abalulekileyo kunye namandla esine 10n.

ngaphantsi kwe-10 Ω ukuxhathisa ngonobumba “R” kunye namanani amabini:

5R6 = 5.6 Ω 3R9= 3.9 Ω R82 = 0.82Ω

Ukukhutshwa kohlobo lwe-SMD:

Ngokuqhelekileyo ibonakaliswe yi-RP × ×, umzekelo, i-10K OHM 8P4R ithetha ukuba izikhonkwane ze-8 zenziwe nge-resistors ezi-4 ezizimeleyo, kwaye ixabiso lokumelana ne-10K OHM yokukhutshwa.

I-NeoDen ibonelela ngezisombululo zomgca wendibano ye-SMT epheleleyo, kubandakanywa i-oven yokuqukuqela kwakhona kwe-SMT, umatshini wokuthengisa amaza, umatshini wokukhetha kunye nendawo, umshicileli we-solder paste, i-Oven yokuReflow, isilayishi se-PCB, isikhupheli se-PCB, i-chip mounter, umatshini we-SMT AOI, umatshini we-SMT SPI, i-SMT X- Umatshini we-Ray, izixhobo ze-SMT zokudibanisa, imveliso ye-PCB Izixhobo ze-SMT ezisetyenzisiweyo, njl.
