Paub txog cov resistors

1. Qhov kev tiv thaiv yog dab tsi

Qhov kev txiav txim ntawm kev nres tam sim no yog hu ua tsis kam.Ib qho khoom siv nrog tus nqi kuj yog hu ua cov khoom tiv thaiv.R (Resistor) tau hais ua lus Askiv.

 

2. Kev ua haujlwm siab

Chav tsev yooj yim rau ohm Ω nws cov chav txuas ntxiv muaj ntau txhiab o K Ω megohm M Ω

 

3. Hloov cov qauv ntawm cov ntsuas ntsuas:

1 m Ω = 10 3K Ω = 106Ω

 

4. Hom thiab qauv ntawm kev tiv thaiv:

4.1 Cov khoom faib:

CF: Carbon zaj duab xis

TF: Thick Film

MF: Hlau zaj duab xis

Cov kab mob

4.2 Kev faib tawm los ntawm cov qauv:

Tsau kuj.(R)

Semi-adjustable kuj.(S-VR)

Variable kuj (VR)

4.3 Kev faib tawm los ntawm cov duab:

Xim nplhaib kuj

Daim ntawv tsis kam.

cais tawm

4.4 Kev faib tawm raws li lub zog ntsuas:

1/16W, 1/8W, 1/4W, 1/2W, 1W, 2W, 3W...

Lub zog tuaj yeem txawv ntawm nws cov duab thiab qhov loj me.Lub ntim loj dua, lub zog ntau dua.

 

5. Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm:

Lub ntsiab technical parameters ntawm kuj muaj xws li tus nqi kuj, rated hwj chim, yuam kev ntau yam thiab hais txog.

 

6. Resistance sawv cev txoj kev:

Qhov tseem ceeb thiab qhov tsis zoo ntawm cov resistors feem ntau tuaj yeem sawv cev los ntawm cov cim digital luam tawm ntawm cov resistors lossis los ntawm cov nplhaib xim.Tsuas yog tus lej sawv cev tau piav qhia hauv qab no.

 

Siv peb tus lej:

SMT resistors nrog qhov yuam kev ntawm 5% feem ntau yog luam tawm ntawm tus resistor los ntawm peb tus lej, nrog thawj ob tus lej sawv cev rau tus lej tseem ceeb thiab tus lej thib peb sawv cev rau ntau yam ntawm 10n.

 

Yog sawv cev los ntawm peb tus lej:

Precision resistors feem ntau sawv cev los ntawm plaub tus lej, thawj peb tus lej tseem ceeb thiab plaub lub zog 10n.

 

tsawg dua 10 Ω tsis kam nrog tsab ntawv "R" thiab ob tus lej:

5R6 = 5.6 Ω 3R9 = 3.9 Ω R82 = 0.82 Ω

 

Tsis suav nrog SMD hom:

Feem ntau qhia los ntawm RP × ×, piv txwv li, 10K OHM 8P4R txhais tau hais tias 8 tus pins yog tsim los ntawm 4 tus neeg sawv cev ywj pheej, thiab tus nqi kuj yog 10K OHM cais tawm.

 

NeoDen muab tag nrho SMT sib dhos kab kev daws teeb meem, suav nrog SMT reflow qhov cub, yoj lub tshuab siv lub tshuab, tuaj tos thiab tso tshuab, tshuab luam ntawv tshuab luam ntawv, Reflow qhov cub, PCB loader, PCB unloader, nti mounter, SMT AOI tshuab, SMT SPI tshuab, SMT X- Ray tshuab, SMT sib dhos kab khoom, PCB ntau lawm Equipment SMT spare qhov chaw, thiab lwm yam yam SMT tshuab koj xav tau, thov hu rau peb kom paub ntau ntxiv:
