Cov tshuaj pleev tshaj tawm yog qhov siv tau dav hauv kev tsim hluav taws xob niaj hnub.
Lawv yog qhov analogue uas ib txwm tawm los tiv taus, tab sis muaj qhov txiaj ntsig tseem ceeb - qhov loj me. Nws siv cov cuab yeej siv no uas tso cai rau koj los tsim cov kev suav thiab xov tooj cua tshiab hauv xov tooj cua.
Lawv thov rau SMT Technology, uas yog tus cwj pwm los ntawm kev siv hluav taws xob siab tshaj plaws ntawm kev teeb tsa ntawm cov ntawv luam tawm.
Txhawm rau kom tsim cov txiaj ntsig, siv cov tshuab ua yeeb yaj kiab nyias lossis tuab-gligation-gligration, thiab cov khoom siv lawv tus kheej muaj qhov yuam kev sib txawv. Feem ntau cov txiaj ntsig yog 5% lossis 1%, thiab muaj tseeb dua li 0.01%.
Lawv tau siv hauv cov cuab yeej siv kho mob thiab ntsuas cov khoom lag luam thiab cov khoom siv hluav taws xob, khoom siv ntau yam, khoom siv hluav taws xob, thiab lwm yam khoom siv. Muaj ntau cov khoom siv ntawm cov khoom sib txawv, ntawm lawv:
- Tolstopnoe;
- Tsawg-voltage siv los txiav txim siab lub zog tam sim no;
- precision zaj duab xis nrog cov yam ntxwv ruaj khov;
- Corrosive;
- Hloov;
- Los ua ke;
- Yooj yim voltage emissions.
Nta Cim Cov Tshuaj Tiv Thaiv
Txhawm rau taug qab nyob rau hauv cov khoom siv nthuav tawm ntawm nti resistors, nws yog ib qho tsim nyog yuav tsum tau coj mus rau hauv tus account lawv khij. Yuav luag txhua qhov tsim tawm, tsuas yog qhov tshwj xeeb ntawm cov 0402, yog cim.
Cov khoom me me tsis muaj paib, vim tias lawv tsuas yog tsis muaj chaw nyob qhov twg nws tuaj yeem muab nws tso. Yog tias qhov loj tshaj 0805, daim ntawv lo yog nruab ntawm lub resistor, uas muaj 3 tus lej.
Nws yog paub tias cov nti tiv taus ntawm 10%, 5%, raws li 2% sau npe thawj peb tus lej. Txhua tus lej muaj lub ntsiab nruj. Tus lej kawg ntawm cov cim qhia txog tus naj npawb ntawm nom.
Whereas thawj ob tus lej qhia mantissa. Txhawm rau tsim cov zauv taw tes, qee zaum tus ntawv R. tau ntxiv rau cov cim muaj nuj nqis. Nws hloov tawm tias cim 24x102 Ohm, thiab qhov no yog 2.4 com.
Ua raws li cov kev tiv thaiv kev tiv taus, tus nqi tuaj yeem sib cais rau hauv ntau txoj kab E6, E12, ntxiv rau E24. Yog tias qhov kev pheej hmoo ntawm kev tawm tsam me me, nyob rau hauv ib tug lej ntau tshaj li qhov kev cuam tshuam.
Qhov siab tshaj plaws ntawm cov tshuaj tiv thaiv nti yog 200v. Qhov siab tshaj plaws tseem muaj cov qauv tiv taus rau kev teeb tsa yooj yim. Tias yog vim li cas thaum kis tau ib qho tseem ceeb ntawm cov khoom hluav taws xob, piv txwv li 500v, nws tsim nyog muab tso rau ntau cov yaum uas tau txuas nrog hauv cov koob.
